Background and Objective: Mesenchymal stem cells are promising sources of stem cells for tissue repair because of their ability to differentiate into different cells, easy proliferation and culture, and immunomodulatory properties. Despite extensive research on the immunophenotype of mesenchymal stem cells, a lack of specific markers comprises challenges for researchers. The aim of this researc...
