Researchers have discovered a gene that regulates when heart muscle cells stop dividing and develop the specialized characteristics needed for lifelong cardiac function, addressing a fundamental question in cardiovascular biology.
Healthcare professionals are raising concerns about the rapid growth of stem cell injections and orthobiologic treatments like platelet-rich plasma for conditions such as knee osteoarthritis, citing inconsistent results and insufficient scientific evidence despite increasing patient demand.
A team led by pathologist Aaron W. James at Johns Hopkins Medicine found in January that sensory neurons in skeletal tissue constantly sense their environment, opening potential new treatment approaches for growth plate injuries.
Tech entrepreneur and anti-aging advocate Bryan Johnson announced he has created what he describes as a 'newborn' version of himself using stem cells, with the goal of growing replacement organs after being diagnosed with autoimmune gastritis.

A Phase 1 clinical trial in Japan reported no tumor formation or graft-related adverse events after transplanting iPSC-derived neural stem/progenitor cells into four patients with subacute complete cervical spinal cord injuries during two to four years of follow-up. The small, uncontrolled study was designed primarily to assess safety and was not able to establish treatment efficacy.
UPMC and University of Pittsburgh researchers successfully weaned multiple liver transplant patients off all immunosuppressant drugs for over three years using a pre-transplant cell therapy approach, representing a potential breakthrough in organ transplantation.
