The ASCCT is supporting efforts of the Center for Alternatives to Animal Testing (CAAT) at Johns Hopkins University to codify Good Cell Culture Practice (GCCP) for induced pluripotent stem (iPS) cells. With this email, we would like to request nominations (including self) for participation in a 2.5-day workshop to take place in Baltimore June 1-3, 2015. The workshop aims to build on previous efforts (http://www.atla.org.uk/good-cell-culture-practice/ and http://www.atla.org.uk/guidance-on-good-cell-culture-practice/) to develop and publicize GCCP for in vitro test methods using iPS cells. GCCP are important to ensure data standardization, quality, reliability, and reproducibility, and are essential to facilitate the regulatory use of iPSC-based methods. The workshop will bring together a small group of scientific and industry experts, regulators, and journal editors to discuss and agree upon recommended practices. Please send a statement of interest and CV for the nominated person, with clear indication of experience working with iPS cells, to the ASCCT Secretary, Kristie Sullivan, at ksullivan@xxxxxxxx<mailto:ksullivan@xxxxxxxx>. Please include affiliated institution and contact information. Statements should be sent by March 31.
