FGFb AUMENTA A PROLIFERAÇÃO DE CÉLULAS DA RETINA EM CULTURA: VIAS DE SINALIZAÇÃO ENVOLVIDAS
Basic fibroblast growth factor (bFGF) plays a central role during the development of the nervous system. It was already demonstrated the effect of bFGF on retinal cell proliferation. However, the intracellular pathways ... -
IGF-I aumenta a proliferação de células da retina em cultura: vias de sinalização envolvidas
IGF-I is a growth factor playing a role in cell survival, cell proliferation and cell differentiation. The purpose of this work was to study, in vitro, the effect of IGF-I on retinal cell proliferation. Our results show ... -
PAPEL DA CAVEOLINA-1 NO DESENVOLVIMENTO DA RETINA DE PINTO
Caveolin-1 (cav -1) forms the caveolae and is involved in the regulation of cellular differentiation and proliferation. In this work, we studied the cav-1 expression, as well as its function during the development of the ...
