Described herein is a managed, indexed repository of hematopoietic stem cell (HSC) lines and/or blood progenitor cell lines derived from induced pluripotent stem cells (iPSCs) (or embryoid bodies formed from iPSCs), wherein each of the HSC lines, blood progenitor cell lines, embryoid bodies, and/or iPSC lines has corresponding data comprising a set of characterized HLA loci, said corresponding data being stored in a searchable database for retrieval of one or more matching physical cell lines upon query. The repository comprises an HLA-indexed bank of iPSCs, embryoid bodies, HSCs, and/or blood progenitor cells for each of a set of HLA types, for identification and provision of allogeneic cell lines suitable for transplantation to reestablish hematopoietic function in patients with damaged, diseased, or otherwise abnormal bone marrow and/or immune system.
