Scanning electron microscopic photomicrographs showing BM-MSC morphologic features and attachment and growth on β-tricalcium phosphate (β-TCP) scaffolds. (A) Morphology of β-TCP scaffolds without cells; (B) few cells were detected adhered to β-TCP granules after 24 h of culture; (C) abundant cells well adhered to β-TCP granules and active adhesive interactions with the scaffold surface was observed at 7 days; (D) multilayered cultures of BM-MSCs adhered to the β-TCP granules was observed at 14 days. Scale bar: 100 μM.
