Researchers in Prof. Irving Weissman's lab have developed and patented antibodies and methods to prevent the formation of teratomas from human pluripotent stem cells used for regenerative medicine, cell therapy or research.
This is a cell line, AC6.21, from the murine cell line of 6C3Ag^hi phenotype. The cell line supports the proliferation and differentiation of pre-B cells from their hematopoietic precursors in vitro.
