3D Reconstructed Human Epidermis (RHE) from StratiCELL are produced from human primary cells, on permeable 0.63 cm2 polycarbonate cell culture inserts at the air-liquid interface, allowing topical or systemic test item applications. Provided with (RHE-MEL) or without (RHE) human melanocytes, those skin models replicate the 3D structure and function of natural human epidermis. They are ideally suited for research on the skin and its microbial environment.
