Nanovesicles from cells for biomedical applications

National University of Singapore scientists have fabricated nano-sized vesicles from cells via a cell shearing approach that can be used for various biomedical applications.

Parallel alignment of dressing fibers accelerates wound healing

A team of researchers from Singapore has reported the development of a skin-mimicking scaffold by parallelly aligning nanofibers made up of a mixture of polycaprolactone (PCL) and gelatin that enhances wound healing. Their ...

Scientists identify key mechanism controlling skin regeneration

It's sunburn season. Many of us have experienced the pain and peeling that comes from unprotected time in the sun, but we may not focus on a remarkable and vital part of the process: the regeneration of skin as the damaged ...

Collaboration shapes extracellular vesicle retention strategy

Leveraging unique expertise in the spirit of collaboration is one of Carnegie Mellon University's formulas for success. Over the past three years, Phil Campbell and Xi (Charlie) Ren partnered on research related to spatial ...

Hyaluronic acid research could spur new therapeutics

For more than two decades, scientists have puzzled over how vertebrates make the essential polysaccharide hyaluronic acid, which has broad medical applications. One team took a different tack and solved the mystery.

Tiny electric generators could accelerate wound healing

Tiny dressings that generate electricity in response to movement could accelerate wound healing and tissue regeneration. Scientists in Taiwan reviewed the latest advances and potential applications of wound healing technology ...

Encoding hierarchical assembly pathways of proteins

Northwestern investigators have identified a novel approach to control the hierarchical assembly of protein pathways with DNA, according to a study published the Proceedings of the National Academy of Sciences (PNAS).
