The Role of the Notch Signaling Pathway in the Differentiation of Human Umbilical Cord-Derived Mesenchymal Stem Cells

Abstract

Human umbilical cord mesenchymal stem cells (hUCMSCs) exhibit potent self-renewal and multilineage differentiation characteristics. They have garnered substantial attention within the domain of regenerative medicine owing to their therapeutic potential, such as in tissue repair, regeneration, immunomodulation, anti-inflammation, angiogenesis, wound healing, neuroprotection, and neuroregeneration. The process of fate determination is initiated by multiple signaling molecules. During development and tissue homeostasis, the Notch signaling pathway assumes a pivotal function in cell differentiation and the renewal of stem cells. A growing body of research has revealed that the Notch signaling pathwayplays a pivotal role in hUCMSC proliferation and differentiation. The latest progress concerning the crucial functions of the Notch signaling pathway in maintaining homeostasis and determining the cell fate of hUCMSCs is summarized. Furthermore, the authors also summarized the mediators related to the Notch signaling pathway in hUCMSC differentiation, as well as the pathway alterations and mechanisms involved in hUCMSC therapy.
