The positive cells displayed brownish yellow granules on the surface, cytoplasm and intercalated disc.
在细胞表面、胞浆中及闰盘处出现棕黄色颗粒为阳性细胞。
CONCLUSION: During the process of BMMSCs differentiating into cardiomyocytes, intercalated disc-like structure is gradually formed with increase in culture time and cell density.
结论：骨髓间质干细胞分化为心肌细胞过程中，随培养时间延长及细胞密度增加逐渐形成闰盘样结构。
