再生障碍性贫血(简称“再障”)已知可由放射线、药物等化学物理因素引起,有的仍原因不明。国内外学者对于“再障”的病理生理研究发现骨髓细胞存在着增生、分化、成熟及释放障碍,可是这些障碍的发病机理一直不大清楚。目前,国外学者在动物身上进行了大量研究,临床上也进行了探索,认为“再障”的发病是骨髓干细胞受损以及骨髓微环境改变所致。 Aplastic anemia (referred to as “aplastic anemia”) is known to be caused by chemical and physical factors such as radiation and drugs, and some remain unexplained. Domestic and foreign scholars on the “aplastic anemia” pathophysiology study found that bone marrow cells exist proliferation, differentiation, maturation and release disorders, but the pathogenesis of these disorders has been unclear. At present, foreign scholars carried out a large number of studies on animals, and also carried out clinical exploration that “aplastic anemia” is the incidence of bone marrow stem cell damage and bone marrow microenvironment changes caused.
