During development of the retina, programmed cell death helps to establish the final size and distribution of various cell classes in distinct layers of the tissue. Here we show that dying cells in the developing ganglion and inner nuclear layers are clustered spatially and that gap junction inhibitors decrease the clustering of dying cells. To confirm the(More)
The retina of newborn rats consists of the ganglion cell layer (GCL), the inner plexiform layer (IPL), the inner nuclear layer (INL) containing amacrine cells and the neuroblastic layer (NBL). In retinal explants, the GCL enters cell death after sectioning of the optic nerve, whereas there is almost no cell death in the NBL. When protein synthesis is(More)
Programmed cell death was studied in the superior colliculus of the developing rat brain following injections of chloramphenicol. Neonatal rats were either subject to unilateral eye removal or left untouched. Following a 3-h post-operative survival, the animals were perfused with fixatives and frozen sections of their brains were examined for apoptosis(More)
