Clear view on stem cell development

Today, tracking the development of individual cells and spotting the associated factors under the microscope is nothing unusual. However, impairments like shadows or changes in the background complicate the interpretation ...

Chip captures individual cells in minuscule gels

Researchers at the University of Twente's MIRA research institute have developed a chip that can capture and hold individual cells in the exact centre of a minuscule hydrogel droplet. Their novel method keeps cells alive ...

Making vessels leaky on demand could aid drug delivery

The endothelial cells that line blood vessels are packed tightly to keep blood inside and flowing, but scientists at Rice University and their colleagues have discovered it may be possible to selectively open gaps in those ...

'Sister cell' profiling aims to shut down cancer metastasis

In work that could improve understanding of how cancer spreads, a team of engineers and medical researchers at the University of Michigan developed a new kind of microfluidic chip that can capture rare, aggressive cancer ...

Cells calculate ratios to control gene expression

In multicellular animals, cells communicate by emitting and receiving proteins, a process called signaling. One of the most common signaling pathways is the transforming growth factor b (Tgf-b) pathway, which functions in ...
