Stem cell discovery could be key to healing tough-to-fix fractures
The ability of a stem cell originating in skeletal muscle to turn into bone could hold the key to bone healing after catastrophic fractures, according to research at Penn’s Perleman School of Medicine. The researchers find that Prg4+—a type of stem cell that originates in the muscles that support the skeleton—is crucial to bone repairs because the cells could actually transform from muscle cells to bone cells.
Nanoparticle blueprints reveal path to smarter medicines
New research involving Penn Engineering shows detailed variation in lipid nanoparticle size, shape, and internal structure, and finds that such factors correlate with how well they deliver therapeutic cargo to a particular destination.
A generous gift from alumni Glenn and Amanda Fuhrman brings the work of internationally acclaimed artist Jaume Plensa to the University of Pennsylvania. The latest addition to the Penn Art Collection expands Philadelphia's public art.
A massive chunk of ice, a new laser, and new information on sea-level rise
For nearly a decade, Leigh Stearns and collaborators aimed a laser scanner system at Greenland’s Helheim Glacier. Their long-running survey reveals that Helheim’s massive calving events don’t behave the way scientists once thought, reframing how ice loss contributes to sea-level rise.
