The authors explored the therapeutic potential of both mesenchymal stem cells and exosomes in mitigating the COVID-19 induced cytokine storm as well as promoting the regeneration of alveolar tissue, attributed to the intrinsic cytokines and growth factor present in the secretome.
Scientists discuss the potential of therapeutic strategies targeting the biological functions of selenium and selenoproteins for osteoarthritis treatment.
