Generally, humans can regenerate injured tissues in vivo for limited distances of up to 2mm. The further the wound distance is from 2mm the more the wound regeneration will need inducement. By 2009, via the use of materials, a max induced regeneration could be achieved inside a 1 cm tissue rupture. [2]
This cycle can repeat indefinitely, potentially rendering it biologically immortal. This organism originated in the Caribbean Sea , but has now spread around the world. [ citation needed ] Key molecular mechanisms of its rejuvenation appear to involve DNA replication and repair , and stem cell renewal, according to a comparative genomics study.
Holometabolous insects can regenerate appendages as larvae prior to the final molt and metamorphosis. Beetle larvae, for example, can regenerate amputated limbs. Fruit fly larvae do not have limbs but can regenerate their appendage primordia, imaginal discs. [30] In both systems, the regrowth of the new tissue delays pupation. [30] [31]
Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [1] [2] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [3]
The axolotl is less commonly used than other vertebrates, but is still a classical model for examining regeneration and neurogenesis. Though the axolotl has made its place in biomedical research in terms of limb regeneration, [19] [20] the model organism has displayed a robust ability to generate new neurons following damage.
