Chicken claw formation gene brings hope for human finger regeneration

Introduction: Japanese scientists recently announced that they have discovered the gene of chicken claw This achievement has taken a solid step towards the realization of human finger regeneration The research was carried out by a team from the Nara Institute of science and technology in Japan The researchers successfully transplanted the third toe of one chicken to the fourth toe and the second toe of another chicken to the third toe There are four toes on each claw of a chicken, and the number of bones in each toe is different Bwq scientists have long recognized that the Tbx3 gene is missing in people born without a third or fourth finger, while there are about 20 genes similar to Tbx3 in humans and chickens Researchers at the school of science and technology in Nara suspected that TBX gene plays an important role in the composition of different fingers, so they carried out the research Bwq in the experiment, the researchers transplanted the Tbx2 gene into the chicken embryo After a week's growth, they found that the third toe, which was supposed to be composed of three bones, produced four bones, the same as the fourth toe of the chicken, and its appearance was exactly the same as the fourth toe When the researchers transplanted Tbx3 into another chicken embryo for the same experiment, they found that the second toe of the chicken eventually grew into the shape of the third toe The results of this study will be discussed at the Yokohama developmental biologists' Symposium in Japan Scientists believe that it will bring new hope for the recovery and regeneration of human fingers Bwq (author:) shared on feed Weibo to:
