Fig. 1From: Overview: an iPS cell stock at CiRAProduction flow of an iPS cell stock. Production is largely composed of the preparation of the materials (human peripheral blood mononuclear cells (PBMCs) and human umbilical cord blood (HCB)), the PCS and the SCS. The PCS is made from cultured cells, which are then gene-transferred to colony formation and stored at P1. For the SCS, the PCS is recultured and then frozen at P7Back to article page
