Alkaline phosphatase (ALP) activity. The osteogenic differentiation of the cells was evaluated by measuring the ALP activity of cell lysates on (A) tissues culture plates and (B) nanofiber meshes. ALP activity increased for both cell types with time, suggesting osteogenic differentiation. p < 0.05 is considered significantly different (*significantly different from the other cell type at same time point; #significantly different from a previous time point for same cell type; $significantly different from hMSC peak on plate at day 7).
