关于造血细胞的分化过程,由于研究材料、研究方法及观察角度等的不同,长期以来见解不一,创立了许多学派,如以Cunningham等为代表的多元论或彻底的多元论;以Naelgeli及Ehrlich等为代表的二元论;以Aschoff及Schilling等为代表的三元论;和以Maximow等为代表的一元论。各学派之间的分歧是各系统原始血细胞的来源问题。血液学包括造血细胞的研究工作,1856～1926年是形态学时期,其后为病理生理学时期,1945年以后为化学时期,目前已进入动态
The differentiation process of hematopoietic cells has long been divided into different disciplines, such as pluralism or radical pluralism represented by Cunningham et al., Due to differences in research materials, research methods, and observation angles. Naelgeli and Ehrlich et al Represented by the dualism; Aschoff and Schilling as the representative of the ternary theory; and Maximow, etc. as the representative of the monism. Disagreements among the various schools are the source of primitive blood cells in each system. Hematology, including hematopoietic research work, 1856 ~ 1926 is the morphological period, followed by the pathophysiology period, after 1945 for the chemical period, has now entered a dynamic
