MSC growth parameters. Growth parameters of human bone marrow derived MSCs cultured in four different media (see Methods for composition details): medium A (n = 8), B (n = 11), C (n = 11), D (n = 8). a) Number of cells after P0 per 1000 BM-MNCs. b) Proliferation index in P1 (cells seeded/cells extracted after P1). c) P2 MSC yield per 1000 initially seeded BM-MNCs.
