Lab-Made Eggs Produce Healthy Mice 81

ananyo writes "Japanese researchers have coaxed mouse stem cells into becoming viable eggs that produce healthy offspring. Last year, the same team successfully used mouse stem cells to make functional sperm (other groups have produced sperm cells in vitro). The researchers used a cocktail of growth factors to transform stem cells into egg precursors. When they added these egg precursor cells to embryonic ovary tissue that did not contain sex cells, the mixture spontaneously formed ovary-like structures, which they then grafted onto natural ovaries in female mice. After four weeks, the stem-cell-derived cells had matured into oocytes. The team removed the oocytes from the ovaries, fertilized them and transplanted the embryos into foster mothers. The offspring that were produced grew up to be fertile themselves."

    If you're not sure what practical application this research contributes to, consider this: We can now create genetic offspring of infertile people. More than that, we can now create genetic offspring of people without their knowledge or consent. All we need is a stem cell sample. Note recent research that enables skin cells to be turned into stem cells.

    It shouldn't be long before companies are advertising services like 'Have George Clooney's baby' or 'Father Christina Hendricks' child'. That's just the tip of the iceberg. The first child with two daddies -- literally -- is just around the corner.

If you suspect a man, don't employ him.
