These cells can be obtained mainly from bone marrow, umbilical cord blood, and adipose tissue, from which cultures have been established that allow the study of their functional and phenotypic properties. They express CD73, CD90, and CD105 antigens in the absence of hematopoietic antigens CD34 and CD45, as well as different receptors for cytokines and adhesion molecules. Future research will allow us to understand various biological aspects of these cells, which are important in their use in regenerative medicine as a therapeutic measure to solve a wide variety of diseases.<\/p><p><strong>INTRODUCTION<\/strong><\/p><p>Mesenchymal stem cells (MSCs) are multipotent adult cells, with fibroblastoid morphology and plasticity towards various cell lineages such as chondrocytes, osteocytes and adipocytes, among others. They can be isolated and expanded in culture medium due to their properties of adhesion to plastic, differentiation and proliferation\u00a0<em>in vitro.<\/em><sup>1-10<\/sup><\/p><p>Mesenchymal stem cells (MSCs) are characterized by presenting a spindle-shaped morphology with an elongated, central nucleus that contains 2 to 3 nucleoli. In flow cytometry studies, three subpopulations of these cells have been described. One of small, fusiform and agranular cells that they named RS-1; another of small and agranular cells named RS-2; and the last one, made up of large and granular cells that they called mature mesenchymal cells or MSCm. The presence of 2 morphological types in cultures has also been reported, one with a fibroblastoid shape, which is the predominant one, and another represented by larger cells with a rhomboid shape.<sup>1,11-16<\/sup><\/p><p>MSCs can be isolated from different sources, including: bone marrow, umbilical cord blood, adipose tissue, pancreas, liver, skeletal muscle, dermis, synovial membrane, and dental pulp. Several published research groups have pointed out the possibility of also obtaining these cells from other alternative sources, such as amniotic fluid and Wharton\u2019s jelly from the umbilical cord. However, the most commonly used tissues are bone marrow, umbilical cord blood, and adipose tissue.<\/p><p>Recent studies have indicated that there are no<br \/>There were no morphological or immunophenotypic differences between the cells obtained from these tissues, but the results indicated that although umbilical cord blood has a greater potential for expansion, its potential for differentiation is lower, as it does not differentiate into an adipogenic lineage.<sup>13-17<\/sup><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-44d2022 elementor-widget elementor-widget-heading\" data-id=\"44d2022\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">\nCHARACTERISTICS OF CMMS\n<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-ffe271e elementor-widget elementor-widget-text-editor\" data-id=\"ffe271e\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Regarding the isolation and culture from adipose tissue, the cells obtained have a morphology, phenotype and differentiation capacity similar to bone marrow but with greater potential for proliferation.

Numerous studies have shown that MSCs do not allow antigen recognition by interfering with the function of dendritic cells and T lymphocytes, so they have a local immunosuppressive effect due to their ability to secrete cytokines. This effect is enhanced when the cells are exposed to an environment with inflammatory activity or characterized by the presence of high levels of gamma interferon.<sup>19,21,22<\/sup><\/p><p>In studies\u00a0<em>in vitro<\/em>\u00a0MSCs have been shown not to express class II major histocompatibility system antigens, indicating that they constitute a therapeutic potential in graft-versus-host disease because they can reduce or suppress induced immune reactions.<sup>19,23,24<\/sup><\/p><p>In addition, they can affect the functioning of the immune system by other mechanisms. It has been indicated that MSCs can inhibit the proliferation of lymphocytes induced by alloantigens and mitogens such as phytohemagglutinin and concanavalin A, as well as their activation by anti CD3 and CD28 antibodies. It has also been pointed out that MSCs can inhibit the expression of molecules involved in antigen presentation and in co-culture with peripheral blood mononuclear cells, they increase the proportion of T lymphocyte subpopulations with a regulatory cell phenotype.<sup>25,26<\/sup><\/p><p>It has been suggested that many of these effects are predominantly mediated by paracrine factors, as MSCs secrete a considerable number of immunomodulatory factors. It has also been suggested that immunosuppressive action could be linked to the involvement of other immunoregulatory systems.<\/p><p>As a complement to the above data, it can be noted that CMMs\u00a0<em>in vitro<\/em>\u00a0can inhibit the proliferation of T and B lymphocytes, support the development of regulatory T cells, decrease the lytic activity of natural cytotoxic or natural killer cells (in English,\u00a0<em>Natural Killer Cells<\/em>) and cytotoxic T lymphocytes, inhibit the differentiation of monocytes into dendritic cells.<sup>27<\/sup><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1cd120b elementor-widget elementor-widget-heading\" data-id=\"1cd120b\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">\n\nCLINICAL APPLICATIONS OF MBCS\n<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-933898a elementor-widget elementor-widget-text-editor\" data-id=\"933898a\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Due to the high multipotential capacity, plasticity and actions of MSCs, they are of great interest for clinical application (<a href=\"https:\/\/revhematologia.sld.cu\/index.php\/hih\/article\/view\/19\/19#tab2_03\">Table 2<\/a>).

This application has been demonstrated in the porcine heart where a significant reduction in the size of the injured tissue, neovascularization and reduction of apoptosis levels have been observed.<sup>21,24<\/sup><\/p><p>Another clinical application of MSCs is in bone repair. It has been proven\u00a0<em>in vivo<\/em>\u00a0In mice and dogs with craniofacial and long bone defects, the direct administration of these cells and their use on matrices such as hydroxyapatite\/tricalcium phosphate have yielded satisfactory results.

In addition, important studies are being carried out in diabetes mellitus, neurodegenerative diseases and liver regeneration.<sup>1,19,24<\/sup><\/p><p>With very positive results, these cells are used in burn victims, in skin lesions secondary to radiotherapy, where epithelial regeneration, angiogenesis, and significant histological hydration have been demonstrated. Different studies are being carried out for the use of MSCs in wound healing, either through systemic administration or by topical application at the wound site. Due to the exposed nature of the skin, the direct application of these cells in cases of polytraumatized individuals and severe burns is a very promising option. The use of MSCs in the treatment of chronic wounds has multiple objectives: to accelerate tissue repair, to cushion inflammatory events, and to reduce or eliminate scar formation.<\/p><p>Another alternative is to use MSCs to stimulate angiogenesis. Some studies have shown that these cells have a positive effect on the recovery of blood flow, which is explained by experimental evidence indicating the generation and incorporation of endothelial cells derived from MSCs, to the capillaries in their formation and by the results of recent studies that have shown that these cells also promote angiogenesis by the secretion of cytokines such as VEGF-A, FGF-2, and IL-6.<sup>17,20-<\/sup><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>C\u00e9lulas madre mesenquimales: aspectos relevantes y aplicaci\u00f3n cl\u00ednica en la medicina regenerativa Dra.
