The human stratum corneum comprises several levels of flattened corneocytes that are divided into two layers: the stratum disjunctum and stratum compactum.

The epidermis is the outermost of the three layers that comprise the skin, the inner layers being the dermis and hypodermis.

Without fibroblasts, the wound site cannot regenerate extracellular matrix and epidermis skin cells cannot proliferate over the wound site. [ 6 ]
