John B. Gurdon and Shinya Yamanaka awarded the 2012 Nobel Prize in Physiology or Medicine

John B. Gurdon (left) and Shinya Yamanaka (right) awarded the 2012 Nobel Prize in Physiology or Medicine

The Nobel Prize in Physiology or Medicine 2012 was awarded today, October 8, 2012, jointly to Sir John B. Gurdon (Gurdon Institute, Cambridge, United Kingdom) and Shinya Yamanaka ( Kyoto University, Kyoto, Japan, and Gladstone Institute, San Francisco, CA, USA) “for the discovery that mature cells can be reprogrammed to become pluripotent“. The Nobel Assembly at Karolinska Institutet (Stockholm, Sweden) decided to award The Nobel Prize in Physiology or Medicine 2012 jointly to John B. Gurdon and Shinya Yamanaka. According to the published Press Release: “The Nobel Prize recognizes two scientists who discovered that mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. Their findings have revolutionised our understanding of how cells and organisms develop“. The International Society for Transgenic Technologies (ISTT) wishes to congratulate both excellent scientists for their outstanding achievements and the very much deserved Nobel Prize they have just been awarded.

John B. Gurdon demonstrated in 1962 that adult frogs could be obtained by the transplantation of nuclei from endoderm cells of Xenopus laevis donors ranging from late blastulae to swimming tadpoles.  In 1966, John B. Gurdon continued his studies on cellular reprogramming in frogs and reported that fertile adult male and female frogs, genetically marked as of solely donor origin, had been obtained from the transplantation of nuclei from intestinal epithelial cells of Xenopus laevis feeding larvae. In 1975, John B. Gurdon reported that tadpoles could be obtained from nuclei transplanted from keratinized skin cells of adult frogs. However, no adult frogs were obtained from nuclear transfer experiments involving adult somatic cells. As concluded by Gurdon and Byrne in 2003, these first series of results obtained by John B. Gurdon, “established the general principle that the process of cell differentiation does not necessarily require any stable change to the genetic constitution of a cell. Thus, cell differentiation depends on changes in the expression not content of the genome“. Similar principles had been envisaged and proposed, but could not be proved, in 1938 by the German embryologist Hans Spemann (awarded the 1935 Nobel Prize in Physiology or Medicine).

Forty years later, after the outstanding results obtained by John B. Gurdon, Shinya Yamanaka reported in 2006 the identification of  four transcription factors (Oct3/4, Sox2, c-Myc, and Klf4) capable of reprogramming any somatic cell into a cell with properties of a pluripotent stem cell, similar to embryonic stem (ES) cells. Those cells were named as inducible pluripotent stem cell (or iPS cells) and greatly revolutionized the regenerative medicine field and cellular reprogramming studies since then. Yamanaka’s experiment provided a totally innovative method to obtain human pluripotent stem cells, with great regenerative potential, without requiring the use of human embryos, an achievement that has been greatly acknowledged by members of the society who did not accept, according to their private beliefs, the previous use of human embryos to obtain pluripotent stem cells. John B. Gurdon and Shinya Yamanaka had already been awarded jointly the 2009 Albert Lasker Basic Medical Research Prize “for discoveries concerning nuclear reprogramming, the process that instructs specialized adult cells to form early stem cells — creating the potential to become any type of mature cell for experimental or therapeutic purposes“.

The history of nuclear transplantation and cellular reprogramming has been silently advancing since the beginning of last century, and progressed through a series of phenomenal milestones that were regularly achieved. Starting with the pioneer experiments and the vision of Hans Spemann (1938), then the first nuclear transfer success in frogs by Briggs and King (1952), of course the experiments carried out by John B. Gurdon in the 60′s and early 70′s, already mentioned, and also the studies by Marie DiBerardino (1967) on the effect of cell cycle in the nuclear transfer success, and other, more recent, describing the role of single transcription factor being able to change the fate of a cell (Harold Weintraub, 1987) or the direct reprogramming experiments, betweeen different cellular haematopoietic types, pioneered by Thomas Graf since 1990. However, in my opinion, the one single study that, for the first time, demonstrated that a nucleus from an adult terminally and fully differentiated somatic cell (i.e. a cell derived from mammary gland tissue) could give rise to a fertile normal adult, closing the circle of life, was the birth of Dolly, the sheep, obtained by Ian Wilmut and his collaborators from the Roslin Institute in 1996 and reported in a famous paper in Nature in February 1997.

Ian Wilmut and Dolly the sheep in 1997

Ian Wilmut and Dolly the sheep in 1997

The impact of Wilmut’s study on Biology, Biomedicine, Biotechnology and on the entire Society was phenomenal, tremendous (unfortunately not always positive, independent of him, with intense and never ending debates beyond science) and triggered many subsequent studies, including the use of human pluripotent stem cells, isolated by Thomson and Gearhart teams in 1998, and their potential in regenerative medicine, and eventually the work by Yamanaka and many other. The Nobel Assembly has limited this Nobel award to Gurdon and Yamanaka, who fully deserved the Nobel Prize, but, unfortunately, they did not include other scientists that were instrumental for the progress in reprogramming studies, particularly Ian Wilmut. Dolly’s experiment  is only referred briefly in the advance information provided to interested readers. After discussing this issue the whole day with many colleagues, I believe I speak on behalf of many by stating that a Nobel Prize awarded to Gurdon, Wilmut and Yamanaka, could have been a much better and balanced choice. Gurdon himself stated that he would have liked to share this Prize with Ian Wilmut.  But this is just wishful thinking and the reality is, as usual, different. Having said that, I want to congratulate once again John B. Gurdon and Shinya Yamanaka for this Nobel Prize.

On a final sad note, after all the excitement associated with this Nobel Award to reprogramming techniques, we have been informed of the sudden death of Keith H. Campbell, biologist (1954 – 2012), who passed away last Saturday, October 6, 2012. Keith H. Campbell was one of the main co-authors, together with Ian Wilmut, of Dolly’s Nature paper in 1997 (Viable offspring derived from fetal and adult mammalian cells. Wilmut I, Schnieke AE, McWhir J, Kind AJ, Campbell KH, Nature 1997 Feb 27;385(6619):810-3). Keith H. Campbell was currently working at the School of Biosciences, University of Nottingham, UK.

 

Transgenic mice obtained from androgenetic haploid embryonic stem cells

Transgenic mice obtained from androgenetic haploid embryonic stem cells (W Li et al. Nature 000, 1-5 (2012) doi:10.1038/nature11435)

Prof. Xiao-Yang Zhao (ISTT Ordinary member and awarded the first ISTT Young Investigator Award in Florida (USA), at the TT2011 meeting) and Prof. Qi Zhou (ISTT Honorary member and awarded the third ISTT Prize in Uppsala (Sweden), at the TT2004 meeting), and his colleagues from the State Key Laboratory of Reproductive Biology, Institute of Zoology, Chinese Academy of Sciences, in Beijing (China), as well as other collaborating institutions, just published a letter in Nature describing how live transgenic mice can be obtained from androgenetic haploid embryonic stem cells (Li et al. Nature 2012).

Mouse androgenetic haploid embryonic stem (ahES) cells can be established by transferring sperm into an enucleated oocyte. These ahES cells maintain haploidy and are stable in culture. In addition, these ahES cells can contribute to the germline of chimeric mice when microinjected into blastocysts. Furthermore, these ahES cells can be delivered by intracytoplasmic injection into mature oocytes, eventually resulting into viable fertile mice that will inherit any genetic modification previously transferred to ahES cells while in culture. As stated by the authors, this work “provides a new approach for genetic manipulation in animal models without available germline-competent ES cells, including non-human primates, as modifications in such haploid stem cells could be transmitted to offspring through intracytoplasmic injection into mature oocytes, which may serve as a more efficient and simple strategy for gene-targeting studies“.

Earlier this year, in the April 27 issue of Cell, an independent study, developed in parallel, from Guo-Liang Xu’s (State Key Laboratory of Molecular Biology) and Jinsong Li‘s (State Key Laboratory of Cell Biology) laboratories from the Institute of Biochemistry and Cell Biology, Shanghai Institutes of Biological Sciences, Chinese Academy of Sciences in Shanghai (China) and their collaborators, including Xiang Gao (Model Animal Research Center, Nanjing University, Nanjing, China), reported similar extraordinary findings.

These three scientists, Qi Zhou (Beijing, China), Jinsong Li (Shanghai, China) and Xiang Gao (Nanjing, China) will participate as invited speakers in the next 11th Transgenic Technology meeting (TT2013) that will be held in Guangzhou (China), on 25-27 February 2013. In particular, both Qi Zhou and Jinsong Li will be presenting their most recent and excellent works on the isolation of androgenetic haploid embryonic stem cells and their use to produce genetically-modified mice.

Once again, the International Society for Transgenic Technologies (ISTT) is pleased to present the latest advances in animal transgenic technology at the TT meetings, next one (TT2013) to be held in Guangzhou (China), in February 2013. Anyone interested in these transgenic techniques and their applications should not miss this great opportunity to learn all these new developments, directly presented by their inventors.

The ISTT journey: from Barcelona to Guangzhou, now it is time for China! The TT2013 meeting

The ISTT journey: from Barcelona to Guangzhou, now it is time for China! The TT2013 meeting

The International Society for Transgenic Technologies (ISTT) was founded shortly after the Transgenic Technology (TT) meeting in Barcelona (TT2005). Since then, the ISTT family has been fortunate to visit several countries, every ~18 months. In 2007 we went to Brisbane (TT2007).  In 2008, we visited Toronto (TT2008). In 2010 we returned to Europe and held the TT2010 meeting in Berlin. For 2011 we visited the USA for the first time, and organized the TT2011 meeting in St Pete Beach (Florida). And, now, the next TT meeting (TT2013) is planned for China, in Guangzhou. This has been one of our aims and challenges, since the foundation of the ISTT, namely, holding a TT meeting in Asia, in China. Now it has become a reality. The 11th Transgenic Technology meeting (TT2013) will be held in Guangzhou (China), on 25-27 February 2013, organized by Prof. Ming Zhao (Chair) (Southern Medical University, Guangzhou) and his Organizing and Advisory Committees, immediately after celebrating the Chinese New Year of the Snake. More than 30 speakers have confirmed their participation, to discuss about ES cells, iPS cells, targeted nucleases (ZFNs and TALENs), cryopreservation and reproduction techniques, running a transgenic facility, mouse genetics, epigenetics, ethics and animal welfare, transgenesis in other vertebrates, animal models of disease, etc… among many other interesting topics. At the TT2013 meeting, the ISTT will award the 9th ISTT Prize for outstanding contributions to transgenic technologies to Prof. Allan Bradley,  Director Emeritus of the Wellcome Trust Sanger Institute (WTSI), in Hinxton (UK), and leader of the Mouse Genomics Team at WTSI.

In addition, a 3-day hands-on practical workshop (28 February-2 March 2013) will be offered in Guangzhou after the TT2013 meeting, addressing basic microinjection techniques, piezo injection, laser-assisted application, non-surgical implantation, mouse colony management and other interesting topics. This workshop is organized by Wenhao Xu (University of Virginia, Charlottesville, VA, USA), Chair,  Ming Zhao (Southern Medical University, Guangzhou, China), Jing An (Cancer Institute, Southern Medical University, Guangzhou, China) and Liangping Li (Sun Yat-sen University, Guangzhou, China).

Don’t miss this opportunity to hear the latest advances in animal transgenic by world experts! Time is going fast and first deadlines (15 October 2012), for registering at reduced fees, for submitting abstracts, for applying for ISTT registration awards and for nominating candidates for ISTT Young Investigator awards are rapidly approaching.

See you all in China!

Structural and Functional Concepts in Current Mouse Phenotyping and Archiving Facilities

Structural and Functional Concepts in Current Mouse Phenotyping and Archiving Facilities

Anyone interested in building, modifying or renewing an animal (mouse) facility, with the aim of using it eventually for archiving (cryopreservation) and/or phenotyping purposes might find interesting reading the following article, which we prepared through the execution of the European Project INFRAFRONTIER.

Structural and Functional Concepts in Current Mouse Phenotyping and Archiving Facilities. Kollmus, Heike; Post, Rainer; Brielmeier, Markus; Fernández, Julia; Fuchs, Helmut; McKerlie, Colin; Montoliu, Lluis; Otaegui, Pedro J.; Rebelo, Manuel; Riedesel, Hermann; Ruberte, Jesús; Sedlacek, Radislav; de Angelis, Martin Hrabé; Schughart, Klaus . Journal of the American Association for Laboratory Animal Science, Volume 51, Number 4, July 2012 , pp. 418-435(18).

Abstract from JAALAS journal web page:

Collecting and analyzing available information on the building plans, concepts, and workflow from existing animal facilities is an essential prerequisite for most centers that are planning and designing the construction of a new animal experimental research unit. Here, we have collected and analyzed such information in the context of the European project Infrafrontier, which aims to develop a common European infrastructure for high-throughput systemic phenotyping, archiving, and dissemination of mouse models. A team of experts visited 9 research facilities and 3 commercial breeders in Europe, Canada, the United States, and Singapore. During the visits, detailed data of each facility were collected and subsequently represented in standardized floor plans and descriptive tables. These data showed that because the local needs of scientists and their projects, property issues, and national and regional laws require very specific solutions, a common strategy for the construction of such facilities does not exist. However, several basic concepts were apparent that can be described by standardized floor plans showing the principle functional units and their interconnection. Here, we provide detailed information of how individual facilities addressed their specific needs by using different concepts of connecting the principle units. Our analysis likely will be valuable to research centers that are planning to design new mouse phenotyping and archiving facilities.

What are we talking about in the transgenic-list?

What are we talking about in the transgenic-list?

After 16 years and more than 20,000 messages posted one could ask: what are we talking about in the transgenic-list? What are the topics mostly discussed in this very popular list among people interested in animal transgenesis? One way to address this question is by using Wordle, a program that analyzes a text and extract the words that are mostly used and draws a graphic where the most frequent words appear more prominently.

Download a WORDLE for the transgenic-list (tg-l): small, big, huge.

What you see above is the result of providing Wordle with the subjects from these more than 20,000 messages posted through the tg-l over the past 16 years. Watching the resulting graphic provides a rather clear answer: we appear to be mostly talking about ES cells, mice, embryos, transgenic, injection, IVF, DNA, etc…  but clearly, ES cells is the most popular topic at the tg-l. Intreresting. A simple but very informative manner to present the usage of words in subjects of messages posted through the transgenic-list.

EMMA Cryopreservation Workshop: a meeting report

EMMA Cryopreservation Workshop: a meeting report

The EMMA (European Mouse Mutant Archive) Cryopreservation Workshop took place earlier this week in Madrid, May 7-8, at the main campus of CSIC, with an excellent success, organized by EMMA, supported by the EC-7th Framework Programme and co-sponsored by the International Society for Transgenic Technologies (ISTT). Sixty participants from many countries around the world gathered to present and discuss, in depth, the latest approaches, methodologies and techniques available for the efficient cryopreservation of mouse strains, through embryo, sperm and ovary cryopreservation. In addition to invited speakers and invited participants, the workshop was attended by delegates from EMMA nodes and 12 ISTT members. As many as 21 talks were delivered, by selected invited speakers, representing the different major archiving iniatives currently existing (EMMA, MMRRC, The Jackson Laboratory, RIKEN, APN, CMMR, AMMRA) and the research and development initiatives, as well as state-of-art protocols in the field. Presentations, abstracts and pictures from this EMMA Cryopreservation Workshop are freely available to anyone interested, from the meeting web site, and can be also accessed from ISTT and EMMA web sites. The remaining presentations will be progressively added upon receiving the approval from the corresponding guest speakers.

At EMMA, we envisaged this cryopreservation workshop as a forum to brainstorm and discuss in depth the latest technological advances in cryopreservation, including sperm and embryo cryopreservation, updated IVF methods and related techniques as ovary cryopreservation, laser-assisted and piezo-driven ICSI, transportation of frozen material and other technical and logistic challenges relevant to the operation of current mouse embryo/sperm archives. We believed we entirely fulfilled the expectations and all participants went back home, to their research institutions, loaded with new ideas, updated solutions and suggested improvements that can be explored and applied for a most efficient management of a mouse embryo/sperm cryopreservation bank. All participants agreed to continue organizing this type of focused workshops in the near future. The ISTT will be always there, ready to support these very interesting initiatives.

World Map of Transgenic Core Facilities

World Map of Transgenic Core Facilities

At the International Society for Transgenic Technologies (ISTT) web site, according to the aims of our Society. we care to provide the entire scientific community with as much information as possible regarding how and where to generate genetically modified animals, particularly transgenic and knockout mice, as useful animal models for research projects in biology, biotechnology and biomedicine. One of these resources of information is the World Map of Transgenic Core Facilities, currently holding more than 125 links to web sites of transgenic core facilities located in 27 countries, world wide. The transgenic core facilities can be easily found in a list, arranged per country, or using a useful Google Maps built-in feature depicting the geographic location of each transgenic facility.

Is your transgenic core facility not yet listed in the World Map of Transgenic Core Facilities offered from the ISTT web site? No problem. Whether public or private, whether based on an academic environment or associated with a company, all transgenic core facilities, all initiatives meant to produce transgenic animals (mice, rats, other mammals, other vertebrates,…) on demand, for research purposes, are welcome and we, at the ISTT, will be pleased to include all these links in our web site. Please contact us at istt@transtechsociety.org and send us your web link and contact details of your transgenic core facility and we will be more than happy to add your transgenic core facility to the list of World Map of Transgenic Core Facilities.

Thanks for submitting the web site of your Transgenic Core Facility to the ISTT.
