血小板发现于1842年,经过半个多世纪的时间,于1906年才确认为是从巨核细胞脱落下来的小块胞质。近二十余年来,由于现代生物化学的发展,电镜的应用,才逐步对血小板的形成及其功能,有了较完整的概念。现简要介绍如下。 Platelet was found in 1842, after more than half a century, in 1906 was identified as a small piece of cytoplasm that came off from megakaryocytes. In the recent twenty years, due to the development of modern biochemistry, the application of electron microscope gradually obtained the complete concept of platelet formation and its function. Now brief introduction is as follows.
