Mitochondria behind blood cell formation

New Northwestern Medicine research published in Nature Cell Biology has shown that mitochondria, traditionally known for their role creating energy in cells, also play an important role in hematopoiesis, the body's process ...

Forever young—how stem cells resist change

This 'before and after' image could be thought of as stem cells' equivalent of an advert for anti-wrinkle cream: 'look how cells stay young!' It shows that a molecule called microRNA-142 allows stem cells to remain unchanged, ...

DNA-based nanodevices for molecular medicine

Researchers from Aalto University have published an article in the recent Trends in Biotechnology journal. The article discusses how DNA molecules can be assembled into tailored and complex nanostructures, and further, how ...

Watching nanoscale assembly live

Ebola virus, Alzheimer's amyloid fibrils, tissue collagen scaffolds and cellular cytoskeleton are all filamentous structures that spontaneously assemble from individual proteins.

New tool aids stem cell engineering for medical research

A Mayo Clinic researcher and his collaborators have developed an online analytic tool that will speed up and enhance the process of re-engineering cells for biomedical investigation. CellNet is a free-use Internet platform ...

A protein that can mean life or death for cells

Each cell in an organism has a sensor that measures the health of its "internal" environment. This "alarm" is found in the endoplasmic reticulum (ER), which is able to sense cellular stress and trigger either rescue responses ...
