New Source of Stem Cells: Amniotic Fluid
`After seven years of toiling, scientists at the Wake Forest University School of Medicine and Harvard School of Medicine report they have isolated stem cells from a new source: amniotic fluid. The researchers not only succeeded in separating the progenitor cells from the many cells residing in the watery fluid in the placenta surrounding an embryo, but were also able to coax the cells to differentiate into muscle, bone, fat, blood vessel, liver and nerve cells.
According to lead author Anthony Atala, director of Wake Forest’s Institute of Regenerative Medicine, 99 percent of the U.S., population could conceivably find genetic matches for tissue regeneration or engineered organs from just 100,000 amniotic fluid samples. [..]’
