Study challenges long-held assumption of gene expression in embryonic stem cells

Researchers have determined that the transcription factor Nanog, which plays a critical role in the self-renewal of embryonic stem cells, is expressed in a manner similar to other pluripotency markers. This finding contradicts the field's presumptions about this important gene and its role in the differentiation of embryonic stem cells.

Breakthrough: Sensors monitor cells at work

Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell's outer membrane, which seals and protects all living cells, to the cell's interior. A team has now developed a groundbreaking new way to measure the activity of transporter proteins in living organisms.
