Research on mesenchymal stem/stromal cells is ongoing, with studies exploring their origin, immune regulation, and potential clinical applications. Various investigations are examining the use of these cells in treating diseases, including lung diseases and kidney disease, as well as their ability to enhance vaccine efficacy and counteract age-related immune decline. The development of optimized manufacture and cryopreservation methods for these cells is also being investigated, with some studies incorporating technologies like artificial intelligence to enable personalized therapeutic strategies.
