... normal situations in order that stress fibers are not formed. At high magnification, we detected radial actin bundles on the hexagonal basal membranes of these axis-turning fibers in fresh lenses ( Fig. S4 ). Previous studies by Bassnett et. al. showed that in chick lens fibers the hexagonal basal...

Classic studies using chick and mammalian lenses revealed that cell proliferation is low in the anterior region and high in the peripheral region of lens epithelium. This highly proliferative peripheral region is called...
