体外培养家兔和树鼩为主动咏平滑肌细胞,分别观察各自的高脂血清对平滑肌细胞生长的影构,以~3H-胸腺嘧啶核苷(~3H—TdR)掺入细胞DNA,用液体闪烁计数器计数。结果表明:兔高脂血清对兔平滑肌细胞生长有显著的增殖作用,而树鼩高脂血清对树鼩平滑肌细胞的生长未见显著的促进增生作用。
Rabbit and tree shrews were cultured in vitro and the positive cells of smooth muscle cells were observed respectively. The structures of smooth muscle cells were observed by 3H-thymidine incorporation (~ 3H-TdR) Counter count. The results showed that rabbit hyperlipidemic serum had a significant proliferative effect on the proliferation of rabbit smooth muscle cells, whereas the high fat serum of tree gall did not significantly promote the proliferation of the smooth muscle cells of the tree flounder.
