Suntanner, Heal Thyself: Exosome Therapy May Enable Better Repair of Sun, Age-Damaged Skin

Via NC State News | September 18, 2019

In the future, you could be your very own fountain of youth – or at least your own skin repair reservoir. In a proof-of-concept study, researchers from North Carolina State University have shown that exosomes harvested from human skin cells are more effective at repairing sun-damaged skin cells in mice than popular retinol or stem cell-based treatments currently in use. Additionally, the nanometer-sized exosomes can be delivered to the target cells via needle-free injections.

Exosomes are tiny sacs (30 – 150 nanometers across) that are excreted and taken up by cells. They can transfer DNA, RNA or proteins from cell to cell, affecting the function of the recipient cell. In the regenerative medicine field, exosomes are being tested as carriers of stem cell-based treatments for diseases ranging from heart disease to respiratory disorders.

“Think of an exosome as an envelope with instructions inside – like one cell mailing a letter to another cell and telling it what to do,” says Ke Cheng, professor of molecular biomedical sciences at NC State, professor in the NC State/UNC-Chapel Hill Joint Department of Biomedical Engineering and corresponding author of a paper describing the work. “In this case, the envelope contains microRNA, non-coding RNA that instructs the recipient cell to produce more collagen… Continue reading.

Dr. Ke Cheng Inducted into Medical and Biological Engineering Elite

Via AIMBE | March 28, 2019

WASHINGTON, D.C.—The American Institute for Medical and Biological Engineering (AIMBE) has announced the induction of Ke Cheng, Ph.D., Professor, Molecular Biomedical Sciences, Biomedical Engineering, Pharmacy, North Carolina State University and University of North Carolina Chapel Hill, to its College of Fellows.

Election to the AIMBE College of Fellows is among the highest professional distinctions accorded to a medical and biological engineer. The College of Fellows is comprised of the top two percent of medical and biological engineers. College membership honors those who have made outstanding contributions to “engineering and medicine research, practice, or education” and to “the pioneering of new and developing fields of technology, making major advancements in traditional fields of medical and biological engineering, or developing/implementing innovative approaches to bioengineering education.”

Dr. Cheng was nominated, reviewed, and elected by peers and members of the College of Fellows for “contributions in designing new biomaterials and targeted cell therapies for tissue engineering and regenerative medicine”
