Researchers report on new way to deliver healing stem cells to kidney injury patients

A new ex vivo drug delivery system has been shown to keep MSCs viable longer and reprogram the peripheral immune response toward organ repair. The study's results suggest that SBI-101 can impact a peripheral immune response that can be transmitted to local tissue damage in vital organs, including the kidney.
