Summary:
A new study led by investigators at Joslin Diabetes Center and Harvard University has found that ovulated egg cells, or oocytes, in adult female mice are not formed from germ cells in the blood or bone marrow. These findings refute a controversial recent study conducted at Massachusetts General Hospital (MGH), which itself contradicted the long-held belief that female mammals are born with a finite number of oocytes that cannot be replenished or regenerated if lost to injury or disease by suggesting that transplanted bone marrow or peripheral blood cells were capable of generating new oocytes in the ovaries of recipient mice.
Commentary: This finding illustrates why federal funding of embryonic stem cell research is necessary. This study was replicated and disproved. This should be a model for the federal government to follow by funding research so experiments can be repeated to ensure that results can be proved, or disproved, with the highest degree of scientific accuracy possible.
