The healing power of pig snouts
The healing power of pig snouts Cells taken from the snouts of genetically
engineered pigs have worked to help heal severed spinal cords in
rats. Scientists hope that the experiment can help them find a wayt
to use animal cells to help humans with spinal cord injuries.
Researchers looked to the olfactory bulbs of pigs-- the parts that
do the hard work of sniffing out food-- because they are rich in
cells known as olfactory ensheathening cells (OEC's) and Schwann
cells. These cells help regenerate and grow nerve cells, expecially
the long axons that connect one neuron to another. AUGUST 31, 2000
