Mast cells with the morphological and biochemical properties of mucosal mast cells (MMC) appear and proliferate to form the predominant cell type in rat bone marrow cultures stimulated with factors from antigen- or mitogen-activated lymphocytes. Conditioned media causing a selective proliferation of MMC were derived from mesenteric lymph node cells of Nippostrongylus brasiliensis-infected rats restimulated in vitro with specific antigen or from normal or infected rat mesenteric lymph node cells stimulated with concanavalin A. MMC growth factor is not produced by T-cell-depleted mesenteric lymph node cells or by the mesenteric lymph node cells of athymic rats. By contrast, MMC precursors are present in the bone marrow of athymic rats and are normally receptive to the growth factor produced by the lymphocytes of thymus-intact rats. The thymus dependence of MMC hyperplasia is thus based on the requirement of a thymus-independent precursor for a T-cell-derived growth promoter.
具有黏膜肥大细胞(MMC)形态和生化特性的肥大细胞出现并增殖,成为在由抗原或丝裂原激活的淋巴细胞产生的因子刺激的大鼠骨髓培养物中的主要细胞类型。导致MMC选择性增殖的条件培养基来自用特定抗原在体外再次刺激的巴西日圆线虫感染大鼠的肠系膜淋巴结细胞,或来自用刀豆球蛋白A刺激的正常或感染大鼠的肠系膜淋巴结细胞。MMC生长因子不是由去除T细胞的肠系膜淋巴结细胞或无胸腺大鼠的肠系膜淋巴结细胞产生的。相比之下,MMC前体存在于无胸腺大鼠的骨髓中,并且通常对胸腺完整大鼠的淋巴细胞产生的生长因子有反应。因此,MMC增生的胸腺依赖性基于非胸腺依赖性前体对T细胞衍生的生长促进剂的需求。
