The pigment epithelium of the monkey. Topographic study by scanning and transmission electron microscopy
M. Sakuragawa and T. Kuwabara
The pigment epithelium of the normal monkey was studied by scanning and
transmission electron microscopy. Appearance of microvilli of the cell are
demonstrated and compared topographically. The apical surface of the
pigment epithelium consists of densely distributed fine microvilli. No
thick portion of the villi or the cell borders are seen in normal
conditions. The attachment of the epithelium and the outer segment is
extremely firm and breakage of the microvilli or outer segments occurs
easily in the attempt to separate these two layers.
