Bioactive BMP-2 produced by encapsulated BMP-hBMSCs promoted hBMSC osteogenesis. a BMP-2 concentration in the medium from the culture with the constructs from the Protein and Gene groups. Day 8 and Day 56 were the medium collection times. (n = 3). b Relative osteogenic gene expression in hBMSCs in the Protein and Gene groups. All data were normalized to the Protein group. (n = 3). c Compressive moduli of constructs from different groups at different time. (n = 4). **p < 0.05
