Fgf-2 Counteracts Loss Of Tgfβ Affected Cells From Rat Lens Explants: Implications For Pco (After Cataract), Kylie Mansfield, Anna Cerra, Coral Chamberlain

Purpose: While cataract surgery initially benefits most patients, many suffer secondary loss of vision because of posterior capsule opacification (PCO). Lens epithelial cells left behind at surgery become aberrant and migrate into the light path. TGF-beta (TGFβ) appears to play a key role in this process by inducing the cells to undergo an epithelial-mesenchymal transition. Paradoxically, it also typically induces them to undergo apoptotic death. The present study was undertaken to investigate the hypothesis that FGF plays a role in PCO formation by promoting the survival of abnormal cells with PCO-like characteristics.

Methods: Rat lens epithelial explants were cultured for ...
