Abstract:
ARPE-19 cells were evaluated as a platform cell line for encapsulated and unencapsulated cell-based delivery technology. ARPE-19 cells were found to be hardy (the cell line is viable under stringent conditions, such as in central nervous system or intra-ocular environment); can be genetically modified to secrete the protein of choice; have a long life span; are of human origin; have good in vivo device viability; deliver efficacious quantity of growth factor; trigger no or low level host immune reaction, and are non-tumorigenic.
