Tissue engineers recruit cells to make their own strong matrix

Imitation may be the sincerest form of flattery but the best way to make something is often to co-opt the original process and make it work for you. In a sense, that's how scientists at Brown University accomplished a new ...

How nanotechnology could keep your heart healthy

Since the heart is such a delicate and critical organ, clinicians usually opt not to intervene with the dead cells that remain after a heart attack or cardiac disease. "But we think that all heart attacks deserve some kind ...

Cells on the move

Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile ...

Detecting molecules on skin

NPL is developing a state-of-the-art technique called 'ambient surface mass spectrometry' that can quickly detect small molecules on the surface of the skin and could benefit the $250 billion a year personal care product ...

Modeling retinitis pigmentosa with iPS cells

Retinitis pigmentosa (RP) is a cluster of genetically determined eye disorders that cause visual defects such as night blindness and narrowing of the field of vision, due to progressive loss of rod photoreceptors. As many ...
