Mayo Clinic identifies molecular switch that steers lung cells to repair or defense

Mayo Clinic researchers have mapped a molecular circuit in alveolar type 2 lung cells that helps determine whether they rebuild tissue or fight infection. The study, published Oct. 14, 2025, in Nature Communications, suggests new paths for regenerative approaches in chronic lung conditions such as pulmonary fibrosis and COPD.
Stem cell therapy lowers heart failure risk after heart attack
A large clinical trial has shown that infusing mesenchymal stem cells from umbilical cord blood shortly after a first heart attack reduces the risk of developing heart failure by nearly 60 percent over three years. The treatment, administered within three to seven days, also improved heart pumping function compared to standard care. Researchers from Shiraz University in Iran led the study, providing strong evidence for stem cells' regenerative potential.
