To date, comprehensive encounter has been accumulated in the use of progenitor cells to restore the function of broken tissues. Now it really is revealed that mesenchymal stem cells (MSC) represent a promising path for regenerative medicine, getting a possible for repair of damaged or pathologically modified tissues [1,2]. This method has two basic possibilities of therapeutic action induced by transplanted cells: the cell differentiation (to substitute a portion of damaged tissue) [3], in addition to a paracrine action (trophic effect) in broken area. MSC can be immunomodulatory, by affecting function and fate of immune cells [4]. The problems related to cell transplantation are mainly linked using the influence of the microenvironment on the properties of cells within a tissue [5]. MSCs have their very own set of receptors for growth elements and cytokines that mediate the influence of external things on intracellular signaling processes and, ultimately, on the function, behavior, and fate of cells. Autophagy plays an essential role in mechanisms that assure the vital activity of all cell types, supporting their homeostasis, differentiation and various types of activity. It has predominantly protective function defending cells from damaging influences. Autophagy is activated by stressful situations (starvation, inflammation), cell differentiation, senescence, aging, and several other situations. Moreover, autophagy happens even in quiescent cells having some functions in resting state. In total, autophagy could provide a promising strategy for improving MSC state in application for purposes of regenerative medicine. two. Mesenchymal Stem Cells (MSC) Mesenchymal stem cells (MSC) are pluripotent cell population, which might be discovered in pretty much all tissues. MSCs is usually characterized by the presence of several specificPublisher’s Note: MDPI stays neutral with regard to jurisdictional claims in Sofpironium web|Sofpironium Technical Information|Sofpironium Data Sheet|Sofpironium custom synthesis|Sofpironium Cancer} published maps and institutional affiliations.Copyright: 2021 by the authors.
