Induced pluripotent cells may make embryonic stem cells unnecessary

For nearly two decades, the medical world and the American public have grappled with the lightning-rod topic of stem cells, in particular the controversy surrounding cells from human embryos. But when researchers four years ago successfully "reprogrammed" adult body cells to become stem cells, some thought the ethical debate was nearly over. Those redirected cells, known as induced pluripotent cells, or iPS cells, show potential as therapy.

New technique explores how cells react to rapidly changing patterns of chemoattractants

Many cell types in higher organisms are capable of implementing directed motion in response to the presence of certain chemical attractants in their vicinity. A team led by Dr. Doris Heinrich of the Faculty of Physics and the Center for NanoScience (CeNS) at Ludwig-Maximilians-Universit-t (LMU) in Munich has developed a novel technique to expose an ensemble of living cells to rapidly varying concentrations of chemoattractants.
