Stem cell therapy makes sterile mice fertile again
Researchers at Shanghai's Jiao Tong University have conducted an experiment involving stem cells and sterile mice. Germline stem cells -- the building blocks of an egg -- were taken from a young mouse and implanted into the ovary of a mouse that had been sterilized. Five to eight weeks later, and this implanted mouse was mated with a healthy to see if pregnancy would occur. The experiment, which tested eight such mice, found that six of the group managed to fall pregnant and deliver healthy offspring.
3D-printed ovaries successfully produce healthy mice pups
Scientists all over the globe are working on the best way to 3D print different human organs for transplant. A team from Northwestern University's Feinberg School of Medicine and McCormick School of Engineering, for instance, are developing 3D-printed ovaries that can boost hormone production and restore fertility. The researchers have even tested their creation on mice, which successfully ovulated and eventually produced healthy pups after their real ovaries were replaced. It even triggered lactation, so the mothers were able to nurse their young.
