If an amphibian chews off one of its arms, it could hide away for weeks without eating and regenerate, he says. Salamander limb regeneration: Salamanders use tissue-specific stem cells to regrow damaged limbs - each stem cell can only make cells belonging to one tissue. They have ten times the amount of DNA as ours, and no one has ever fully sequenced them. He has accelerated healing more than an actual healing factor. In conjunction with Boston Childrens Hospital, they have created a vaccine equity planner that maps the locations of vaccine deserts based on factors such as social vulnerability indexes and transportation access.

Maybe one day this same process can be induced in humans. But like humans, African clawed frogs can't regrow complex limbs and instead heal the wound with scar tissue. How did this mountain lion reach an uninhabited island? The research shows how the same mechanisms that ordinarily provide cellular energy can also drive more exotic processes such as wound healing.

Regenerating joints and joint tissue is the next big mile marker, which Laurencin sees as essential to regenerating a limb that functions and performs in the way he envisions. If you want to keep an iguana as a pet, it . Through the vaccine equity planner, he has been trying to see if there are places where mobile clinics can go to improve access. Laurencin feels other regeneration efforts were hampered by their siloed research methods with chemists, surgeons, engineers all working separately. In time, people who lose limbs due to health conditions, such as diabetes and cancer, could be given a chance to reclaim their independence . Gardiner, however, said humans build entire organ systems in the womb; from just some genetic information a human embryo develops into a complete person in nine months.
