The aim of this work was to define the role of pRb depletion in the proliferation and differentiation of avian retinoblasts in vitro. For this purpose vectors expressing pRb short hairpin RNA were used to deplete pRb in cultures of avian neuroretinal cells. Down regulation of pRb was observed by Western blot and quantification of nuclear pRb. Cell proliferation and differentiation were studied following...
During eye development, bone morphogenetic proteins (BMPs) exert multiple actions on both early and late patterning and differentiation processes. However, the roles of BMP signaling in retinal differentiation are not well understood. To gain insight into a novel role of BMPs during retinal development, we proceeded to retrovirally directed misexpression of the BMP antagonist Drm/Gremlin in the chicken...
