TOKYO —
Japanese researchers have created a functioning human liver from stemcells, a
report said Friday, raising hopes for the manufacture of artificial organs for
those in need of transplants.
A team of
scientists transplanted induced pluripotent stem (iPS) cells into the body of a
mouse, where it grew into a small, but working, human liver, the Yomiuri
Shimbun said.
Stemcells
are frequently harvested from embryos, which are then discarded, a practice
some people find morally objectionable. But iPS cells -- which have the
potential to develop into any body tissue -- can be taken from adults.
A team led
by professor Hideki Taniguchi at Yokohama City University developed human iPS
cells into "precursor cells", which they then transplanted into a
mouse's head to take advantage of increased blood flow.
The cells
grew into a human liver 5 millimetres (0.2 inches) in size that was capable of
generating human proteins and breaking down drugs, the Yomiuri reported.
The
breakthrough opens the door to the artificial creation of human organs, a key
battleground for doctors who constantly face a shortage of transplant donors.
Taniguchi's
research could be "an important bridge between basic research and clinical
application" but faces various challenges before it can be put into
medical practice, the Yomiuri said.
An abstract
of Taniguchi's research was delivered to regenerative medicine researchers
ahead of an academic conference next week, but Taniguchi declined to comment to
AFP before the meeting.
Two
separate teams, one from the United States and one from Japan, discovered iPS
cells in 2006.
