Osteogenesis of hESC-MSCs was promoted on nanofibrous (NF) matrices. The cells were seeded onto polylactic acid flat films or NF matrices and cultured with 100 nM Dex in combination of 50 ng/mL BMP-7. One- and 2-week cultures were collected for quantification of ALP content (A). Three- and 4-week cultures were collected for quantification of calcium content (B). *p < 0.05, **p < 0.01.
