Researchers at OHSU have demonstrated a new technique to treat #infertility by turning skin cells into #oocytes, or eggs. Shown here, an image of an oocyte with a bright image of a skin cell nucleus before #fertilization.

Sorry for the pay wall on this but bottom line is, scientists have taken XY cells from the tail of an adult mouse, cultured them in a proper soup of growth factors and produced an oocyte which they then fertilized with mouse sperm, implanted the embryo in a surrogate and produced viable pups! #sexcell #fungibility #malecellsmakeoocytes #oocytes #mouse
