UCLA stem cell researchers from the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research led by Dr. Amander Clark have developed the first biological resource that maps critical stages of human egg and sperm cell development during fetal life.
The resulting map has important implications for future research of infertility, such as for cancer survivors left unable to create eggs or sperm due to chemotherapy or radiation treatment. Another important result of this research is a better understanding of the cellular origins of testicular cancer, which is believed to begin in males during fetal life.
A Montana State University researcher and her co-researchers are receiving international attention for showing that skin cells from infertile men can be used to create the precursors of sperm – research that holds promise for treating male infertility (…)
The team took skin cells from men who suffer from a genetic disorder, known as azoospermia, which prevents them from producing sperm. Those skin cells were then turned into stem cells, specifically, induced pluripotent stem cells, or iPSC. Like other stem cells, iPSC have the ability to become any other type of cell.
The team then implanted the stem cells into the
