Researchers report technique for freezing and preserving genetically enhanced pig embryos

...ore fertilizing them with muscle cells from a male pig containing modified genetic material. The resulting embryos were then frozen at the blastocyst stage. Upon thawing, embryos were transferred to surrogate female swine. Embryos placed in the oviducts of two surrogates led to pregnancies that produced...

Reversing 'hibernating' heart muscle focus of UB researchers

Previous research has shown that, while restoring blood flow to these "hibernating" regions improves function and a patient's prognosis, cells in the left ventricle (the heart's main pumping chamber) often remain ...

Neurons grown from embryonic stem cells restore function in paralyzed rats

...ation, so Dr. Kerr's group is working to develop a pig model. Researchers also need to test human embryonic stem cells to learn if they will work in the same way as the mouse cells. It has only recently become possible to grow motor neurons from human embryonic stem cells, Dr. Kerr adds. However, if the...

A vaccine to kill tapeworm

... essential step in the tapeworm's life cycle. If a pig eats the eggs then, as in humans, the eggs hatch in the intestine, burrow through the gut wall and travel to muscles, where they form cysticerci. The infection rarely causes symptoms in pigs. Only cysticerci- not eggs- can develop into the adult for...
