Fibrillar collagen inhibits proliferation and induces differentiation of human placenta derived multipotent cells into smooth muscle cells .

周伯岷：纤维胶原蛋白诱导人类胎盘衍生多功能干细胞分化成平滑肌细胞及抑制细胞增生作用。

Thus , despite otherwise unchanged molecular architecture , shorter fibrillar samples show enhanced cytotoxic potential than their longer counterparts .

所以分子结构相同，短的纤维样本比长的纤维增加了细胞毒性倾向性。
