Indirect immunoperoxidase detection of fibronectin (FN) in the ventral frog epidermis showed that only one type of epidermal cell, the mitochondria-rich cells (MRC), was FN-detected. FN was found in MRC having rounded, flask-like and intermediate shapes, located at different levels of the epidermis between the stratum germinativum and the stratum corneum. These cells contained cytoplasmic FN particularly in the form of small granules. Our results support the view that MRC differ from other epidermal cells in their in vivo FN localizations.
间接免疫过氧化物酶法检测青蛙腹部表皮中的纤连蛋白(FN)显示,只有一种表皮细胞,即富含线粒体的细胞(MRC)能检测到FN。在生发层和角质层之间的表皮不同层次中,呈圆形、烧瓶状和中间形态的MRC中发现了FN。这些细胞含有细胞质FN,尤其是呈小颗粒的形式。我们的结果支持这样一种观点,即MRC在体内FN定位方面与其他表皮细胞不同。
