Lonza now provides these highly specialized cells with optimized growth medium based on proprietary isolation techniques developed by Lonza Walkersville's Research and Development group. Clonetics® HRPE cells are sold at passage 2 and guaranteed through 5 additional population doublings.
Cells are also tested for cell-specific performance in the RtEGM™ Retinal Pigment Epithelial Growth Medium. Performance markers include = 90% positive for pancytokeratin, = 10% positive for fibroblast contamination, = 90% for tight conjunctions, and = 1% positive for endothelial marker CD31.
The retinal pigment epithelium (RPE) is comprised of hexagonal cells organized into a monolayer that is densely packed with pigment granules. RPE cells play a critical role in visual function and photoreceptor viability.
