The zebrafish retina maintains two populations of stem cells: first, the germinal zone or ciliary marginal zone (CMZ) contains multipotent retinal progenitors that add cells to the retinal periphery as the fish continue to grow; second, radial glia (Müller cells) occasionally divide asymmetrically to generate committed progenitors that differentiate into(More)
1. Mechanical fluctuations of the cell membrane (CMFs) in human erythrocytes reflect the bending deformability of the membrane-skeleton complex. These fluctuations were monitored by time-dependent light scattering from a small area ( approximately 0. 25 microm2) of the cell surface by a method based on point dark field microscopy. 2. Exposure of red blood(More)
