Chouhan D(1), Mandal BB(2). Wound healing is a complex and multi-step process based on the dialogue between numerous cellular actors. Studies have reported remarkable examples of scarless healing in fetal skin and appendage regeneration in adult skin following the infliction of large wounds. According to Johns Hopkins Medicine, after about 3 months, most wounds are repaired. And while there's not a whole lot that can be done for scars that are already there, in 2017 researchers figured out how to make fresh wounds heal as normal, regenerated skin, instead of the usual scar tissue - something that was previously thought to be impossible in mammals. Electrical stimulation at the wound site is a compelling strategy for skin wound repair. The involvement of bone marrow stem cells in the formation of granulation tissue and epidermis has long been known. According to the citation report, the application of a 3D bioprinting approach for wound healing and skin regeneration started in 2012 with the use of collagen bioinks.

Significance: The regeneration of healthy and functional skin remains a huge challenge due to its multilayer structure and the presence of different cell types within the extracellular matrix in an organized way. UCLA researchers and colleagues have developed a wound-healing biomaterial for cuts, burns and other injuries that could significantly reduce scar formation and result in healthier, stronger skin. They identified a specific population of progenitor cells that reside within the dermis and which aid in wound healing. Protection from mechanical injury, chemical hazards, and bacterial invasion is provided by the skin because the epidermis is relatively thick and covered with keratin. Silk Biomaterials in Wound Healing and Skin Regeneration Therapeutics: from Bench to Bedside. Secretions from sebaceous glands and sweat glands also benefit this protective barrier.
