Scientists have successfully created early-stage sperm cells from human
Achieving a new pioneering medical advancement in infertility scientists have been able to produce early-stage sperm cells using skin cells of infertile men.
Stanford University researchers informed that they took skin cells from infertile men and converted them into stem cells called induced pluripotent stem cells, and then implanted those cells in the tubules of mice testes.
Stem Cell Network explained the complex procedure of converting skin cells back into stem cells. They said, “when some adult cell types are taken, grown in plastic dishes and given specific genetic instructions, over time a small number of these cells will reverse from their differentiated state and develop the ability to redifferentiate.”
It can’t be denied that this experiment is a major breakthrough in infertility treatment for men but a writer for The Guardian points out one major concern which is that though the cells implanted in the (mice) tubules developed into early-stage sperm cells, but several others also became small tumors.
This shows a clear risk of cancer in the men. This is one major shortcoming which needs to be taken care of by scientists.
