Basic characterization of hiPSC BSCC will provide a basic characterization of hiPSC including: - Maintenance in culture as established line for 10 passages. Only clones surviving, as typical pluripotent stem cell colonies for an extended period are likely to be true stem cells Human ES cell surface antigen profile Expression of key endogenous pluripotency-associated genes Evidence of transgene silencing NOTE: In addition to the basic characterization, several other analyses are likely to be needed before the cells can be used for experiments aiming at tissuespecific disease modelling. BSCC can help with these according to agreement with the client. These include for example: - Authentication of cell line identity by DNA fingerprinting. Karyotype analysis, either by G-banding (Medix) or by bead hybridization (Karyo-Lite, Turku center for Biotechnology) Pluripotent differentiation potential in vitro (in embryoid bodies) or in vivo (in mouse teratomas) Targeted differentiation of pluripotent stem cells into definitive endoderm progenitors
