hUCMSC seeding on CPC scaffolds. (A) hUCMSCs attached to CPC-chitosan-fiber composite. “C” stands for hUCMSC. “E” refers to the cytoplasmic extensions of the cell. “F” designates polyglactin fiber in CPC. (B) hUCMSC extensions attaching to the nano-apatite that makes up the CPC matrix. (C) RT-PCR of osteogenic differentiation of hUCMSCs attaching to CPC showed high alkaline phosphatase (ALP) gene expression at day 4. (D) Osteocalcin (OC) gene expression peaked at day 8. Each value is the mean of 5 measurements, with the error showing one standard deviation (mean ± SD; n = 5).
