自从用遗传标记细胞证明所有的血细胞都来源于一个共同的前体——造血干细胞以来,人们的注意力就集中到设法搞清楚是什么东西控制干细胞向某一型血细胞分化,而不向另一型血细胞分化,以及各种血细胞的相对数量是如何调节的。尽管早巳知道,组织环境对干细胞的分化有重要影响,但对组织环境产生这种影响的方式,看法都很不一致。各种具有功能的、成熟
Ever since all of the blood cells have been proven by genetic marker cells to originate from a common precursor, hematopoietic stem cells, attention has focused on trying to figure out what controls the differentiation of stem cells into one type of blood cell, Type of blood cell differentiation, and the relative number of various blood cells is how to regulate. Although it has long been known that the tissue environment has a major influence on the differentiation of stem cells, the way in which this effect is felt on the tissue environment is highly disagreeable. A variety of functional, mature
