Transgenic Animal Technology. A Laboratory Handbook (3rd edition, 2014)

Twenty years after the publication of the first edition and twelve years after the release of the second edition of this book, Carl A. Pinkert (Auburn University, College of Veterinary Medicine, Auburn, AL, USA) in association with Elsevier, releases now the third edition of his famous transgenic manual: “Transgenic Animal Technology. A Laboratory Handbook. 3rd edition, 2014“. As it will be familiar to readers of the two previous editions of this useful and unique handbook, this is not only a manual to understand how to make a transgenic mouse. This handbook looks beyond mice and it contains protocols to prepare a wide variety of genetically-modified animals, including: rats, rabbits, poultry, fish, pigs, ruminants and non-human primates. In addition, this compilation of helpful methods includes a number of chapters devoted to understand and improve all steps of transgenesis, from vector design, analysis of transgene integration and the evaluation of transgene expression. Finally, the book also includes cryopreservation methods, an embryo culture section, a review of standard nomenclature and a selection of databases and internet resources currently available in the field.

This handbook is a worth addition to any library, laboratory or transgenic facility, complementary to other available manuals on the subject, but unique in the sense that it exquisitely illustrates current transgenic methods that can be applied to a wide variety of animal species, beyond mice.

Carl A. Pinkert has been helped in his outstanding Editorial task by a large group of co-authors, experts in their subjects, including some ISTT members: Satoshi Akagi, Anna V. Anagnostopoulos, Benjamin P. Beaton, Cory F. Brayton, Steve Brown, Anthony W.S. Chan, Tom Doetschman, Rex A. Dunham, David A. Dunn, Janan T. Eppig, Almudena Fernandez, Tatiana Flisikowska, Vasiliy Galat, Robert A. Godke, Philip Iannaccone, Michael H. Irwin, Larry W. Johnson, Yoko Kato, Teoan Kim, Alexander Kind, Bon Chul Koo, Mo Sun Kwon, Daniel J. Ledbetter, Michael J. Martin, Kazutsugu Matsukawa, Colin McKerlie, Lluis Montoliu, Paul E.

Manipulating the Mouse Embryo. A Laboratory Manual (4th edition, 2014)

Manipulating the Mouse Embryo. A Laboratory Manual (4th edition, 2014)

A bit more than 10 years later, from the last edition (3rd, 2003) published, the classical manual, the “Bible” in our field has been renewed, updated, upgraded and recently published in its fourth edition. The new “Manipulating the Mouse Embryo. A Laboratory Manual. 4th edition, 2014” has just been released, published by Cold Spring Harbor Laboratory Press and edited by Richard Behringer, Marina Gertsenstein, Kristina Vintersten Nagy and Andras Nagy. The editors, the same team that produced the 3rd edition of this useful manual, should be praised once again for a brilliant work done, accommodating the latest techniques in mouse embryo manipulation, while not forgetting the traditional procedures that must be learnt properly by anyone joining this field of animal transgenesis for the first time.  The editors counted with the help of many additional collaborators, who provided materials and protocols, including many ISTT members, as Marina and Andras are, such as:  Wojtek Auerbach, Ralph Brinster, Jorge Cabezas, Tracy Caroll, Lluis Montoliu, Naomi Nakagata, Jan Parker-Thornburg, Shirley Pease and Thomas Saunders, just to name a few of the many colleagues that shared their expertise and contributed to this 4th edition of the CSHLP manual.

This fourth edition is dedicated to Anne McLaren (1927-2007), one of the brave and gifted pioneer in mouse genetics and embriology, and whom do we all owe a number of standard procedures that we routinely apply in a transgenic laboratory, such as mouse embryo culturing, pseudopregnancy and embryo transfer.

The structure of this 4th edition manual follows that of the 3rd edition, in the sense that chapters and methods are grouped logically and functionally, from a very good summary on mouse genetics and mouse embryo development, to mouse colony management, and followed by a variety of main sections dealing with in vitro and in vivo work, surgical procedures, the production of transgenic mice by pronuclear microinjection, derivation of ES cell lines, using ES cells to generate germline-transmitting chimeras, genotyping protocols, parthenogenesis and nuclear transfer, assisted reproduction techniques, cryopreservation methods, techniques for visualizing gene products and finishing by a chapter devoted to setting up a micromanipulation laboratory and the usual and convenient appendix with receipts for the common buffers and solutions.

Besides this excellent updated version of the CSHLP Mouse Manual, there are several books published on this subject, including the ISTT manual (Springer, 2011) edited by Shirley Pease and Thomas Saunders, and all are worth reading and having them around for consultation, since each one brings their own contribution, their view and their solutions for the adequate learning of how to best manipulate animal embryos, and not all methods and protocols are covered in a single book, hence they are largely complementary. I will be soon reporting in this ISTT blog about additional books recently published in this field.

CRISPR-Cas strategies are discussed and applied everywhere for the targeted modification of genomes. Every day a new lab is considering using CRISPR-Cas for the generation of their subsequent animal mutants. There are many papers regularly being published on this subject and a number of excellent online resources have been prepared by several labs actively working in this field. For newcomers/beginners this might seem (and it is) a lot of information, potentially difficult to digest.

In this regard, from the International Society for Transgenic Technologies (ISTT), we have prepared a simple web page containing a selection of CRISPR-Cas resources and related information, for anyone willing to start using these technologies. Please, feel free to suggest any additional CRISPR-Cas resources you might be aware/using/have developed, which might be worth including in these web pages. Thanks.

In particular, we wish to thank Feng Zhang (MIT/BROAD) and his lab for their efforts, videos (such as this video from Le Cong, PhD, illustrating this post, this video has been made possible thanks to Addgene, and is part of this series), online desing tools, protocols, etc… disseminating these technologies. Feng Zhang will receive the third ISTT Young Investigator Award and will attend the TT2014 meeting in Edinburgh.

The TT2014-associated Zebrafish Transgenesis Workshop: 8-10 October 2014 in Edinburgh

Immediately after the 12th Transgenic Technology (TT2014) meeting, a unique hands-on zebrafish transgenesis workshop will be taking place in Edinburgh, on October 8-10, 2014. This will be the first non-rodent hands-on transgenic workshop ever organized after a TT meeting. This workshop is offered to willing participants registered to attend the TT2014 meeting (October 6-8, 2014). Registration is handled separately and, at first, intended participants should submit their expression of interest to Organizers. Please note that attendance at this meeting is limited to 20 participants only. Due also to high demand for places, there is a selection process in place for all applicants wishing to attend the workshop. Applications should be sent, along with proof of registration to the following email address: zebrafish_tt2014@transtechsociety.org by June 30, 2014. Decisions on the successful applicants will be communicated by July 15, 2014.

The zebrafish is fast becoming a very significant vertebrate animal model system in scientific research; highlighted by the exponential increase in zebrafish-related publications. The role of zebrafish in science is only going to increase in the future; techniques are being constantly developed and more and more people recognise its advantages and benefits to research.

This small freshwater, tropical fish has some clear and unique advantages as a model system; these include its optical transparency, with ex-utero synchronous and rapid development, which allows direct, and continuous in-vivo observation. Genetic and pharmacological manipulation is relatively straight forward and the zebrafish is able to regenerate all organs and tissues. The fish can be maintained under very economic conditions and can be obtained in significant numbers, allowing statistically high N values. Another major advantage is that the developing zebrafish can survive for several days without a cardiovascular system, allowing examination of embryonic-lethal genotypes and phenotypes, from the single-cell stage. Whilst the zebrafish may lack certain (and some obvious) mammalian organs, and despite being physically very different, there are very important genetic and cellular similarities, with development being directly comparable to humans.

The workshop ‘An Introduction to Zebrafish Transgenesis’ follows TT2014 and is the first practical workshop in a non-rodent model species. The practical sessions will start with gene expression interference using classical morpholino microinjection on Day 1, which is complemented on Day 2 with microinjection of a simple fluorescent transgene construct. The scheduled embryology sessions are separated by a wide-ranging series of talks from leading experts in aquatic transgenics. Both the tutorials and practical instruction will provide all the information needed to perform husbandry and gene manipulation in the early zebrafish embryo. Topics include: husbandry best practise, microinjection principles, transgenesis and mutagenesis using recombinases, imaging and cryopreservation.

Appointed teachers and instructors for this zebrafish workshop include: Liz Patton, Carl Tucker, Koichi Kawakami, Stephen Ekker, Keith Joung, Henry Roehl, Robert Kelsh, Martin Denvir, David Lyons, Dirk Seiger, Yi Feng and Karthikeyani Paranthaman.

If you are interested to learn how to work with this alternative vertebrate animal model do not miss this extraordinary opportunity to become familar with basic zebrafish transgenesis techniques and register your interest to attend this hands-on workshop, associated with the TT2014 meeting.

In Memory of Ueli Märki

In Memory of Ueli Märki

On Thursday I got the very sad information that Ueli (Ulrich) Märki passed away on Saturday last week. This is a great loss for all that got to know him and we all mourn with his family about this tragic loss.
I first got in contact to Ueli during my university time in Heidelberg in the beginning of the 90th, while he was still working for RCC in Switzerland. I got to know him as a very dedicated scientist (thanks for teaching me a lot of mouse genetics Ueli!) a very nice colleague and in the long-run as a dear friend. When we initiated the first Transgenic Symposium in Heidelberg in 1993, he was one of the supporting persons, encouraging us to get this meeting up and running.
During the forthcoming years I met Ueli at various meetings and it was always a pleasure and a lot of fun together with him. I especially enjoyed the unofficial parts at the meetings, which we spend with a good beer or wine, discussing all the world and his brother. Even when I moved over to Sweden and he joining Taconic we kept the contact even when we then didn’t meet so often. And it was again he helping me a lot with setting up the first TT Meeting in Stockholm 1999. He was also one of the first to join the ISTT when it was founded, always supporting us with good ideas, but also challenging us when something didn’t seemed to go the right way.
I was looking forward meeting him again at the next GV-SOLAS meeting this year in September. I am going to miss and will hold him in good remembrance, as valued researcher and dear friend.
Our deepest regrets and condolences go to his family and his close friends. We are going to miss him unspeakably.

Johannes Wilbertz
