Algorithms offer insight into cellular development

Through RNA sequencing, researchers can measure which genes are expressed in each individual cell of a sample. A new statistical method allows researchers to infer different developmental processes from a cell mixture consisting ...

Deadly bacterial infection in pigs deciphered

The Clostridium perfringens bacterium is part of the large Clostridium genus which can cause various fatal illnesses in animals and humans. Clostridium infections are widespread. These bacteria are dangerous because they ...

Like a zipper: How cells form new blood vessels

Blood vessel formation relies on the ability of vascular cells to move while remaining firmly connected to each other. This enables the vessels to grow and sprout without leaking any blood. In the current issue of Nature ...

Cellular Workouts Strengthen Endothelial Cells' Grasp

(PhysOrg.com) -- University of Pennsylvania bioengineers have demonstrated that the cells that line blood vessels respond to mechanical forces -- the microscopic tugging and pulling on cellular structures -- by reinforcing ...

A human endothelial cell that was flown to the International Space Station and returned to Earth for analysis is helping researchers keep astronauts healthy in space.

HSPC 'seeds' reveal VCAM-1+ macrophage role in homing process

Hematopoietic stem and progenitor cells (HSPCs) give rise to all blood lineages that support life. HSPCs, like seeds, need a suitable microenvironment to maintain their function. A process called "homing" allows HSPCs to ...

Identification of a unique 'switch' for blood vessel generation

By systematically analyzing epigenetic changes in angiogenesis-stimulated vascular endothelial cells, Professor Takashi Minami (Kumamoto University, Japan) and his team have found a unique epigenetic modification (bivalent ...
