简介 幼淋巴细胞 胞体:直径10-18μ 胞核:占细胞绝大部分,居中或稍偏位。圆形或椭圆形。淡紫红色,染色质细致,排列匀称,核膜浓厚,界限清晰,核仁1-2个,清楚淡兰色。 胞浆:量少,淡兰色或深兰,核周界明显,无颗粒,无Auer's小体。
骨髓中壁龛最重要的成分是成骨细胞,同时一类型成纤维细胞调控胸腺幼t淋巴细胞的成熟。
In the bone marrow the most important elements of the niche appear to be osteoblasts, whilst a less defined population of fibroblasts regulates the maturation of immature t cells in the thymus.
They both proliferate, increase in number, and they differentiate; they differentiate from immature B-cells into antibody producing cells.
淋巴细胞将迅速增殖,数量大幅提高,同时发生分化,幼B淋巴细胞分化,形成能够分泌抗体的细胞
Cells share signals with each other, and that leads to activation of a specific cell population if we're thinking about a vaccine that produces antibodies, that leads to activation of B-cells, immature B-cells, which do two things.
细胞与细胞之间存在信号传递,而这将激活特定的细胞群体,如果是一些能够产生抗体的疫苗,抗体将会激活B淋巴细胞,幼B淋巴细胞,使其发生两种变化
