Human keratinocyte cells isolated from a normal human foreskin. These cells are frozen at the first passage and exhibit robust growth characteristics in cell culture with fast doubling times and consistent morphology. Keratinocyte cells are widely used in iPSC reprogramming workflows, cell therapy development, and the study of viral infections, oncogenesis, wound healing, and skin grafting applications. These cells have a high differentiation capacity. Vial contains approximately 500,000 cells. Shipped with dry ice.
