sGAG content via Blyscan assay.

Data represent means ± S.D. (n = 3) represents pooled of EBs from 3 experimental repeats. *Significant difference compared with decellularized EB scaffold, P<0.01.数据以平均值±标准差（Standard Deviation，S.D.）表示，n=3代表取自3次独立实验重复的拟胚体（Embryoid Bodies，EBs）混合样本。*与脱细胞拟胚体支架（decellularized EB scaffold）相比，差异具有统计学意义（P<0.01）。
