Iron absorption by the rat intestinal epithelial cell has been studied by differential centrifugation of mucosal homogenates and by electron microscopic autoradiography. Autoradiography of both subcellular pellets and whole gut confirmed the biochemical findings. Mitochondria play a quantitatively significant role in iron metabolism within the epithelial cell but do not take part in the transport of iron across the cell during iron absorption.
通过对黏膜匀浆进行差速离心以及电子显微镜放射自显影术，对大鼠肠道上皮细胞的铁吸收进行了研究。亚细胞沉淀和整个肠道的放射自显影证实了生化研究结果。线粒体在上皮细胞内的铁代谢中起着数量上显著的作用，但在铁吸收过程中不参与铁跨细胞的转运。
