大鼠小肠M细胞的表面形态和抗原粘附

扫描电镜观察发现，大鼠小肠Ｐｅｙｅｒ‘ｓ结表面可区分出三种类型的Ｍ细胞，其表面形态明显不同，对抗原（ＳＰＡ－金）的粘附能力亦有差别，提示Ｍ细胞处于不同的发生阶段或功能状态，其起源或演变可能与吸收细胞有一定的关系。

SURFACE MORPHOLOGY AND ANTIGEN ADHESION OF INTESTINAL M CELLS IN RATS

By scanning electron microscopy, three types of M cells could be distinguished on the surface of intestinal Payer's patches in rats. There were significant differences in their surface morphology and capability for adhesion of SPA-gold injected into intestinal lumen. The result suggests that M cells can recognize antigen and non-antigen materials and their origin and development may be related to the absorptive cells.
