骨髓不仅促进前B 淋巴细胞的增殖、分化,而且也是产生血清抗体的主要器官。骨髓内的抗体产生细胞是由外周淋巴器官生发中心的B 淋巴细胞经血液循环迁移而来,骨髓细胞分泌一系列因子促使迁移而来的这些细胞进一步分化成熟,分泌特异性抗体。
Bone marrow not only promotes the proliferation and differentiation of pre-B lymphocytes, but also the main organ that produces serum antibodies. Antibody-producing cells in the bone marrow are migrated from the B lymphocytes of the peripheral lymphoid organ germinal centers through the blood circulation. Bone marrow cells secrete a series of factors to further migrate these cells to mature and secrete specific antibodies.
