Not unlike looking for the proverbial needle in a haystack, a team of Michigan State University researchers have found a gene that could be key to the development of stem cells – cells that can potentially save millions of lives by morphing into practically any cell in the body.
The gene, known as ASF1A, was not discovered by the team. However, it is at least one of the genes responsible for the mechanism of cellular reprogramming, a phenomenon that can turn one cell type into another, which is key to the making of stem cells (…)

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.

An extremely valuable source of eggs has been discovered in female mice. The discovery was described as a potentially infinite source of female fertility, or germline stem cells, which can continue producing new egg cells in adults, which could be a cure for sterility and menopause.
The discovery was made by Ji Wu of the University of Shanghai Jiao Tong and contradicts previous research on the female reproductive system, possibly paving the way for new prospects to treat sterility and revolutionize female reproduction, which after menopause could make use of germline stem cells that were previously isolated
