V型胶原蛋白广泛地分布于血管壁、基底膜及神经内膜等部位,具有促进神经再生及抗凝血等重要生理功能。据国外文献报道,从人胎盘中提取的V型胶原有两种形式,即AB_2和ABC。国内由于缺乏V型胶原纯品,对其研究受到了限制。本实验参照Miller等人介绍的文献,从人胎盘中提取了V型胶原蛋白(AB_2)。 V-type collagen is widely distributed in the blood vessel wall, basement membrane and endometriosis and other parts, with promoting nerve regeneration and anti-clotting and other important physiological functions. According to foreign literature, V type collagen extracted from human placenta has two forms, namely AB_2 and ABC. Due to the lack of pure V-type collagen, its research has been limited. In this experiment, according to the literature introduced by Miller et al., Type V collagen (AB_2) was extracted from human placenta.
