Once the invading microorganisms have been brought under control, the skin proceeds to heal itself. The ability of the skin to heal even after considerable damage has occurred is due to the presence of stem cells in the dermis and cells in the stratum basale of the epidermis, all of which can generate new tissue .
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Skin tissue can be regenerated in vivo or in vitro. Other organs and body parts that have been procured to regenerate include: penis, fats, vagina, brain tissue, thymus, and a scaled down human heart. One goal of scientists is to induce full regeneration in more human organs. There are various techniques that can induce regeneration.
After the extended success of “Cobra Kai,” which started out on YouTube before finding new life on Netflix, the franchise returns to the big screen just over 40 years after Ralph Macchio first ...
Healing must happen by repair in the case of injury to cells that are unable to regenerate (e.g. neurons). Also, damage to the collagen network (e.g. by enzymes or physical destruction), or its total collapse (as can happen in an infarct) cause healing to take place by repair. [citation needed]

Artificial skin made by Integra composed of an outer silicone film and inner matrix of cross linked fibers. Artificial skin is a collagen scaffold that induces regeneration of skin in mammals such as humans. The term was used in the late 1970s and early 1980s to describe a new treatment for massive burns.
The Army is producing new training videos aimed at preparing soldiers to absorb moral shocks long enough to keep them in the fight. But the Pentagon does not formally recognize moral injury, and the Navy refuses to use the term, referring instead to “inner conflict.”
