Collagen content via Sircol Collagen 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，样本量n=3，所有数据均来自3次独立重复实验中收集的胚胎体（Embryoid Bodies，EBs）的混合样本。 *与脱细胞胚胎体支架（decellularized EB scaffold）相比，差异具有统计学意义（P<0.01）。
