Nanostimulators for tissue repair

Stem cells that are injected into body tissues are short lived.  To advance tissue regeneration, “. . . researchers at University of Illinois at Urbana-Champaign have been able to attach tumor necrosis factor α (TNFα), a compound that motivates stem cells to produce paracrine factors, directly onto stem cells. The team relied on liposomal nanoparticles to hold onto TNFα molecules, which they were able to bind to the stem cells and use them to generate the compounds that promote vessel growth.”  They added, ““Our idea is to collect adipose tissue in the operating room, separate the stem cells, mix in the nanostimulators and reinject them into the patient – all in one procedure.”  MORE
