Hematopoietic stem cell characterization in β-TCP scaffolds in vitro. C-kit+ cells were subjected to the different β-TCP/matrix hybrids over 14 days in vitro. a Percentage of DAPI−-viable cells after 14 days of c-kit+ cell culture with and without collagen I/III/Matrigel® on β-TCP scaffolds in the presence of MSC support. b Expansion/decrease of lin−Sca1+c-kit− stromal cells normalized to day 4 of the culture. c Expansion/decrease of lin− normalized to day 4 of the culture. Mean ± SD of three independent experiments. d Colony-forming potential of cells isolated from 500- and 800-μm β-TCP scaffolds with and without collagen I/III/Matrigel® in the presence of MSC support at day 4 and day 14. Results are mean ± SD of three independent experiments. CFU colony-forming unit, GEMM granulocyte-erythrocyte-macrophage-megakaryocyte, GM granulocyte-monocyte. without
