Gene Delivery to Human Limbal Stem Cells Using Viral Vectors.

ABSTRACT: Limbal stem cell (LSC) transplantation is a promising treatment for ocular surface diseases especially LSC deficiency. Genetic engineering represents an attractive strategy to increase the potential for success in LSC transplantations either by correcting autologous diseased LSCs or by decreasing the immunogenicity of allogeneic LSCs. Therefore, two popular viral vectors, adeno-associated viral (AAV) vector and lentiviral (LV) vector, were compared for gene delivery in human LSCs. Transduction efficiency was evaluated by flow cytometry, quantitation of viral genomes, and fluorescence microscopy after introducing eight self-complementary AAV serotypes or LV carrying a green fluorescent protein (GFP) cassette to fresh limbal epithelial cells, cultivated LSC colonies, or after corneal intrast
