Scientists at an English university have grown a miniature artificial human liver in a major medical breakthrough. (http://news.yahoo.com/s/afp/20061031/hl_afp/britainsciencebiotech_061031133215)
Ok, that's pretty neat. They're going to use it to test drug treatments.
But I thought this was really amazing:
The pair extracted blood from the umbilical cords of newborn babies. They were then placed in a "bioreactor" developed by
NASA, which mimics the effects of weightlessness. This allows the cells to multiply more quickly.
Chemicals and hormones are then added to encourage the stem cells to turn into liver tissue.
"We take the stem cells from the umbilical cord blood and make small mini-livers," said McGuckin. "We then give them to pharmaceutical companies and they can use them to test new drugs on.
How do they mimic the effect of weighlessness?
