Abstract

Development of the rat iris was studied electron microscopically. Development of the rat iris began on the sixteenth prenatal day and differentiated actively during the three days before birth. The iris showed mature structure by the end of the postnatal second week. The sequence of the smooth muscle formation from the neuroepithelial cell was specifically described. The differentiation began with formation of the basal infoldings. Myofilaments were found in the celh which had formed a bazement membrane around the infolded bazal and lateral cell membranes.
