其实通过查文献,确实可以发现不少文献表明胎盘中的造血干细胞确实多过脐带血中,问题在于提取过程过于复杂,并且提取物会富含杂质,并没有一个能够提纯同时成本低廉的方法来纯化提取物。至于说文献出处,确实很多,我只举例一篇- D8 H# A% P: B( M4 b+ \8 V! h9 W

Here we show that the human placenta contains large numbers of CD34-expressing hematopoietic cells, with the potential to provide a cellular yield several-fold greater than that of a typical UCB harvest.
