Flipping the 'off' switch on cell growth

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery ...

Novel technique to produce stem cells from peripheral blood

Stem cells are a valuable resource for medical and biological research, but are difficult to study due to ethical and societal barriers. However, genetically manipulated cells from adults may provide a path to study stem ...

Treating vascular disorders with a cell-based strategy

A research team at Weill Cornell Medical College has discovered a way to utilize diagnostic prenatal amniocentesis cells, reprogramming them into abundant and stable endothelial cells capable of regenerating damaged blood ...

Scientists focus on quorum sensing to better understand bacteria

The relatively new field in microbiology that focuses on quorum sensing has been making strides in understanding how bacteria communicate and cooperate. Quorum sensing describes the bacterial communication between cells that ...

The ins and outs of building the sperm tail

Sperm swim, lung cells sweep mucus away, and the cells in the female Fallopian tube move eggs from the ovary to the uterus. Underlying these phenomena are flagella – slender, hair-like structures extending from the surface ...
