Benjamin Reubinoff, Tamir Ben - Hur, and their colleagues at Hadassah University Hospital
in Jerusalem, Israel, and Monash University
in Melbourne, Australia, took a simpler approach, letting the stem
cells multiply
in a culture
dish until they differentiated on their own.
«Alzheimer's disease doesn't strike most people
until they're at least
in their seventies, so you might have to leave the
cells in the
dish for 70 years
until they show any symptoms,» he says.
Until now scientists conducted most biomedical research through animal testing — which often doesn't translate to humans — or
in a petri
dish, a static environment that doesn't let
cells behave as if they are
in the human body.»
