骨髓是人类造血器官,它的细胞增殖动力反应了它的造血功能状态。骨髓造血功能的研究是临床血液学的一个重要课题。骨髓细胞增殖中只有分裂中期的 M 时相可以从形态上识别,而分裂间期(间期细胞)的三个时相(G_1相,S 相和 G_2相)从形态上则无法区分。
Bone marrow is a human hematopoietic organ, and its motility for cell proliferation reflects its hematopoietic state. The study of bone marrow hematopoiesis is an important issue in clinical hematology. Only the metaphase M phase in bone marrow cell proliferation can be identified morphologically, while the three phases (G 1 phase, S phase and G 2 phase) of the interphase (interphase cells) are morphologically indistinguishable.
