Additional file 5: Figure S4. of An engineered multicomponent bone marrow niche for the recapitulation of hematopoiesis at ectopic transplantation sites

(A) Representative TEM images of c-kit+ cells used for initiating co-cultures after immunomagnetic bead selection. (B) TEM images of 4- and 14-day cultured c-kit+ cells on 500-μm β-TCP scaffolds, 500-μm β-TCP/collagen I/III scaffolds, and 500-μm β-TCP/Matrigel® scaffolds. Collagen I/III gels and Matrigel® alone are shown as controls. C-kit+ progenitor cell morphology (of freshly isolated cells) consisting of visible scattered chromatin, prominent nucleoli, and approximated cell diameter of 8–10 μm is shown as reference
