. I n those experiments it was shown that the rate of lens regeneration became related to that of the neural retina. In fact, with regard to regeneration there is increasing evidence of a close interrelationship between these two structures, retina and lens, in many different ways. Tied in with this is the fact that retina pigment cells can give rise not only to neural retina but iris and lens as well (Stone, '55).
Previous experiments had shown (Stone, '50b) that when segments of the wall of the eye were implanted in lentectomized host eyes the retina pigment cells of the grafts developed neural retina membranes. Later, in 1951, Sato considered the results of his interesting experiments on the eyes of adult Triturus pyrrhogaster showing that some of his

Removal of the lens from the eye of an adult newt (Notophthalmus viridescens) is followed by regeneration of a new lens from the dorsal iris epithelial cells at the pupillary margin. This process is dependent upon the neural retina for its normal completion in vivo and in vitro. To examine the relat
## Abstract Since neural retina stimulates regeneration of a lens from the dorsal iris in newts, RNA and protein synthesis in the neural retina was investigated during this process. Incorporation of ^3^Hβleucine using liquid scintillation counting was employed to compare RNA and protein synthesis i
## Gap junctional coupling between progenitor cells of regenerating retina in the adult newt was examined by a slice-patch technique. Retinal slices at the early regeneration stage comprised one to two layers of cells with mitotic activity, progenitor cells. These cells were initially voltage-clamp
