Perhaps in the future, people will be able to recover lost limbs — this, in any case, hinted medical experiments. Scientists already know that under certain conditions the body can grow bones, but they still have not been able to fix the signs of joint growth. It seems that this moment has finally come-researchers from the University of Texas a&M gave mice with amputated toes only two proteins, after which they went to the recovery process.
First, the researchers used a BMP2 protein to start the recovery process of the bone. After that, they added a mixture of BMP9, which began to repair the joints. It is noteworthy that the regeneration process was carried out better if the last protein was added not earlier than a week. The formation of one cartilage layer took about 3 days, and between the bone and joint even formed compounds.
To full limb restoration science is still far away, but she goes for it. Between the skeletons of mice and humans have much in common, so we can assume that the proteins BMP2 and BMP9 may well be applied to the human body. According to researcher Ken Muneoka, mammalian cells are able to regenerate body parts, but for some reason just don’t.
Scientists are full of hope and intend to find out what exactly restrains mammals from natural limb recovery. They believe that proteins BMP2 and BMP9 are to play a greater role in technology for the launch of the regeneration processes. In addition to returning lost limbs, this technology can help in the treatment of degenerative joint diseases. By the way, scientists are already able to regenerate dental tissue.
