PURPOSE To investigate the phenotype of fetal and adult human limbal cells cultured on human amniotic membrane and the ability of cultured adult human limbal cells to repair limbal stem cell deficiency in a rabbit model. METHODS Human adult and fetal limbal cells were isolated and cultured either on plastic plates or on human amniotic membrane. Connexin43, p63, and keratins 3 and 12 (K3 and K...

An antigen was isolated from tumor cells derived from cases of bovine lymphoma which caused the in vitro blastogenesis of lymphocytes from nine of 13 (69%) adult cattle with lymphoma. Lymphocytes derived from five of 122 (4%) normal adult cattle also underwent blastogenesis while lymphocytes from three cases of the sporadic form of lymphoma did not respond. Blastogenesis of lymphocytes from nor...

Purpose Age-related macular degeneration (AMD) is the leading cause of central visual loss among patients over the age of 55 years worldwide. Neovascular-type AMD (nAMD) accounts for approximately 10% of patients with AMD and is characterized by choroidal neovascularization (CNV). The proliferation of choroidal endothelial cells (CECs) is one important step in the formation of new vessels. Tran...
