一、什么是自然花瓣形成细胞? 人体内某些淋巴细胞在一定技术条件下,能和绵羊红细胞结合,当用显微镜观察时,可以看到淋巴细胞的表面,围绕着许多红细胞,其形状好象玫瑰花一样,中心“花蕊”就是淋巴细胞,四周“花瓣”就是绵羊红细胞。绵羊红细胞与淋巴细胞之间的相互作用,不是抗原和免疫活性细胞的免疫反应关系,故人们称这种淋巴细胞为自然花瓣形成细胞。 First, what is the formation of natural petal cells? Some human lymphocytes under certain technical conditions, and sheep red blood cells, when observed with a microscope, you can see the surface of lymphocytes, surrounded by many red blood cells, its shape as if Rose, the center “flower” is the lymphocytes, surrounded by “petals” is sheep red blood cells. The interaction between sheep erythrocytes and lymphocytes is not an immune response between the antigen and the immunocompetent cells, so people call this lymphocyte a natural petal-forming cell.
