  • The Biological Process Of Skin Healing And Skin Homeostasis

    stem cells at the basal layer of epidermis is responsible to maintain skin homeostasis. When cutaneous injuries occur, skin homeostasis and integrity is damaged, leading to fatal traumatizing under severe conditions. Skin wound healing is an intrinsic self-saving chain-reaction, which is crucial in facilitating the replacement of damaged or lost tissue. Immense amounts of research have uncovered the mechanisms underlying this complex and highly regulated process. It is commonly agreed that wound…
