脐带血，脐静脉提取作为无创伤性来源备受关注，特别是对于幼儿心血管先天疾病患者，尤其有意义。在国外，获得伦理道德（ETHICAL APPROVAL）审核是很难的，脐带血是必然首选。 : O: ~$ l6 U, C: v. \5 [( k9 Q& y _4 n6 o0 i. y
‘Recently, endothelial progenitor cells (EPCs) were isolated from peripheral blood CD34, Flk-1, or AC133 antigen-positive cells, which are considered to include a hematopoietic stem cell population, ’ 通过这一段描述不难发现其实和MSC一样，EPC也是某一个细胞群，而不是单一的细胞种类。相信今后会有很多来源发现。作者: henryjia 时间: 2010-10-8 21:06

In the past decade, researchers have defined committed stem or progenitor cells from various tissues, including bone marrow, peripheral blood, brain, liver, and reproductive organs, in both adult animals and humans. Whereas most cells in adult organs are composed of differentiated cells, which express a variety of specific phenotypic genes adapted to each organ’s environment, quiescent stem or progenitor cells are maintained locally or in the systemic circulation and are activated by environmental stimuli for physiological and pathological tissue regeneration. ! h( ]$ E* l2 \; L" y.
