The SKI Stem Cell Research Core stocks, characterizes, and distributes human pluripotent stem cell (hPSC) lines. We perform a variety of hPSC-related applications for the stem cell community at SKI and beyond. We are a part of the Starr Foundation-funded Tri-Institutional Stem Cell Initiative that provides shared stem cell expertise and resources among Memorial Sloan Kettering, Weill-Cornell, and Rockefeller University.
