ABSTRACT
Objective: To investigate the effect of retinoic acid on the differentiation and development of B lymphocytes, and explore the mechanism of vitaminA in increasing the production of antibodies. Method: In vitro cultured cells from children’s normal mesentery lymph nodes, before and after administration of retinoic acid or retinoic acid antagonist, the changes of cell surface markers were analyzed by flowcytometry to observe the differentiation and maturation of B cells. Results: During culture in vitro, the percent of mature CD19+IgM+ B cells increased and relatively immature CD19+IgM- B cells decreased gradually, and the changes were especially obvious at 48 h. The administration of retinoic acid further increased the percent of CD19+IgM+ B cells, and the enhancement was markedly at 24 and 48 h (P
