Regeneration in humans

Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to <a href="/facts/Wound_healing/3NlzV5Qn">wound healing</a>, or partial regeneration, which involves closing up the injury site with some gradation of <a href="/facts/Scar/XSQ92JoG">scar</a> tissue. Some tissues such as skin, the <a href="/facts/Vas_deferens/mjLuacWY">vas deferens</a>, and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury.
Numerous tissues and organs have been induced to regenerate. Bladders have been <a href="/facts/3D_printing/lbvWU3t0">3D-printed</a> in the lab since 1999. Skin tissue can be regenerated <a href="/facts/In_vivo/kWcWyl6f">in vivo</a> or <a href="/facts/In_vitro/evp3hAX6">in vitro</a>. 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. By 2016, regeneration of tissue had been induced and operationalized by science. There are four main techniques: regeneration by instrument; regeneration by materials; regeneration by drugs and regeneration by in vitro 3D printing.
