An embryonic cell’s fate is sealed by the speed of a signal

An embryonic cell’s fate is sealed by the speed of a signalEarly in development, chemical signals tell cells whether to turn into muscle, bone, brain or other tissue. By tracking cells’ responses to signals, researchers found the speed at which the signal arrives has an unexpected influence on that decision. More »

Using geometry, researchers coax human embryonic stem cells to organize themselves

Using geometry, researchers coax human embryonic stem cells to organize themselvesBy confining colonies of human embryonic stem cells to tiny circular patterns on glass plates, researchers have for the first time coaxed them into organizing themselves just as they would under natural conditions.
