Widespread skewed expression of mRNA components correlate with fine tuning of protein production

Widespread skewed expression of mRNA components correlate with fine tuning of protein productionIn numerous tissues and genes, the researchers found lopsided ratios in two parts of mRNA transcripts of genes, one of which carries the code for a protein and one that doesn’t. They suspect some of these skewed ratios may help control protein production, particularly in the embryo, but also in the adult. More »

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.
