TT2016 – President’s Synopsis

The opening night of TT2016 was momentous promising subsequent days filled with good friends and good science. We welcomed more than 700 delegates who attended, and then proceeded to hear a wonderful talk from Andras Nagy (2005 ISTT Prize winner). Andras’ talk was followed by a delicious buffet with wine, friends, colleagues and music. The opening proved to be an excellent portent of what was to come. Over the next three days, we heard many excellent talks—talks that encompassed the use of transgenic technologies, and especially CRISPR/Cas9 technology.

We heard about methods to ameliorate muscular dystrophy, to humanize large animals for xenotransplantation, to make swine resistant to an endemic disease, and to examine infertility in humans. We discussed technologies that would use epigenome to target the “regulome”, that would examine non-coding areas of the genome, that would recapitulate immune syndromes in ES cells, and that would allow us to assess phenotypic changes in embryonic lethal mutant mice using imaging. We learned both the history behind the CRISPR/Cas9 system, and newer CRISPR systems that are in development. We discussed ethics, gene drive, non-injection technologies, new injection technologies, and methods of generating many more oocytes in mice. There were seventeen abstracts chosen for full presentation, examining technological developments, large CRISPR/Cas9 initiatives, and transposon-mediated transgenesis. The remainder of the more than 125 abstract submssions were displayed throughout the meeting in the spacious poster room. Three were chosen as Poster Award winners, including Vera Jansen (Optogenetic tools to study cAMP signaling in cilia and flagella), Charles-Etienne Dumeau (Efficient method for the isolation of functional single cell from the ICM of mouse blastocyst), and Hiromi Miura (Generation of knockdown mice by CRISPR/Cas9-based targeted insertion of artificial miRNA sequence). On the last day, the ISTT Young Investigator Award (sponsored by inGenious Targeting Laboratory) was given to Pablo Ross based on his work developing ES cells in farm animals.

The meeting was preceded by two workshops—one on programmable nucleases (headed by Radislav Sedlacek) and one on cryopreservation (led by Martin Fray, INFRAFRONTIER). Those who attended the workshops were very pleased with the learning opportunities that were afforded them. In addition, immediately following the meeting was one additional workshop on zebrafish transgenesis (Leads: Petr Bartunek, Zbynek Kozmik, Christian Mosimann and Graham Lieschke). All of the workshops were well-attended and greatly appreciated!

There were a number of new initiatives at TT2016. We had Orbis pictus lectures—lectures designed to use pictures and clear descriptions to demonstrate answers to a problem. Richard Behringer gave an excellent, encyclopedic presentation of methods of producing genetically modified animals in a vast variety of species. Later, Thomas Boehm described how lymphoid organs developed throughout evolution to the point where vertebrates now have a thymus. Also, for the first time, we had concurrent sessions. Delegates needed to choose whether to hear about ethics in animal use, or new injection and superovulation technologies. Overall, the scientific program was exceptional!

Departing Board members

The ISTT, Inc. held its third General Assembly just prior to the Gala Dinner. During that meeting, we sadly said goodbye to three departing Board members: Tom Fielder, Boris Jerchow and Wojtek Auerbach. We also reviewed ISTT finances, membership, committee activities, and interactions with our affiliated organizations. One new ISTT initiative that was presented was an outreach committee to our members (and non-members) who perform transgenic technologies in non-rodent (generally large-animal) species. The ISTT large animal group will be headed by Martina Crispo and Bruce Whitelaw. The meeting ended with a presentation inviting membership to attend TT2017 in Salt Lake City, Utah, USA, hosted by Susan Tamowski.

A wonderful time at the Zofin Palace.

The social program prepared by our Czech colleagues was also amazing. Delegates enjoyed the opening buffet with traditional Czech music. However, it was the Gala Dinner that proved to be the high point of the social program. The Zofin Palace was full with partygoers. The wine flowed freely, the food was wonderful, and the string quartet (plus clarinet) fantastic as well. Overall, TT2016 can be considered as one of the best TT meetings ever, and I am proud, as ISTT President, that we helped to host such a wonderful meeting. Thanks so very much to the organizers—Radislav Sedlacek, Inken Beck and Nicole Chambers. Due to their amazing work, the ISTT has again had a successful TT meeting!
