Do hyalocytes synthesize and secrete inhibitors of retinal pigment epithelial cell proliferation in vitro?
Hyalocyte-conditioned medium inhibits RPE cell proliferation in vitro through TGF-beta and at least one other molecule. Production of these factors by hyalocytes in vivo could provide a deterrent for epiretinal membrane formation that may be perturbed under pathologic conditions.
Data support the usefulness of the scales for identifying student alcohol risk and protective factors.
