A group of mod developers may join to form a "mod team". Doom (1993) was the first game to have a large modding community. [6] In exchange for the technical foundation to mod, id Software insisted that mods should only work with the retail version of the game (not the demo), which was respected by the modders and boosted Doom ' s sales.
Hox genes play a massive role in some amphibians and reptiles in their ability to regenerate lost limbs, especially HoxA and HoxD genes. [1]If the processes involved in forming new tissue can be reverse-engineered into humans, it may be possible to heal injuries of the spinal cord or brain, repair damaged organs and reduce scarring and fibrosis after surgery.
This process worked mostly due to both the donor and receiver in this case being identical twins. Nowadays, bone marrow can be taken from people who are similar enough to the patient who needs the cells to prevent rejection. [15] The term "regenerative medicine" was first used in a 1992 article on hospital administration by Leland Kaiser.
The resultant EMG signals of the targeted muscle now represent the motor commands to the missing limb, and are used to drive a motorized prosthetic device. [ 1 ] Targeted sensory reinnervation is a method by which skin near or over the targeted muscle is denervated, then reinnervated with afferent fibers of the remaining hand nerves. [ 2 ]
Sunflower sea star regenerates its arms. Dwarf yellow-headed gecko with regenerating tail. Regeneration in biology is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.

A supernumerary phantom limb is the sensation of having an extra limb or body part despite no such limb actually existing. It is an uncommon syndrome, usually due to some kind of brain injuries in the somatosensory cortex or in some parts of the right hemisphere of the brain, usually due to a stroke in the brain.
Nevertheless, this was a huge leap towards whole lung regeneration and transplants for humans, which has already taken another step forward with the lung regeneration of a non-human primate. [ 63 ] Cystic fibrosis is another disease of the lungs, which is highly fatal and genetically linked to a mutation in the CFTR gene .
A phantom limb is the sensation that an amputated or missing limb is still attached. It is a chronic condition which is often resistant to treatment. [1] When the cut ends of sensory fibres are stimulated during thigh movements, the patient feels as if the sensation is arising from the non-existent limb.
