Due to the wide variety of cytokines and GFs secreted by them, ADSCs can be used for controlled drug release. These cells can be used for proliferation and differentiation of tissues regardless of survival conditions and immunologic problems. Because of their ability to differentiate into various lineages, ADSCs can be used in musculoskeletal problems, diabetes, heart diseases, obesity, neurologic and nephrogenic diseases, and wound healing, as well as applications in regenerative medicine such as osteogenic, cartilage, tendon, muscle, skin, CNS, cardiac and vascularization, as well as liver and even periodontal regeneration. To maintain the highest viability and efficiency, companies that provide ADSCs should offer the best product quality to gain market share and scientists need to acquire an understanding of sources where they can find the best products available. Therefore, in this article, we have reviewed the available products, companies and the market size currently available for ADSCs. Enormous effort has been made to list the most important trials, products and companies currently existent in the field. To achieve better outcomes in scientific research, there is the need to compare the products available and choose the best option according to desired goals. Thus, this paper provides a valuable reference for those interested in the field of ADSCs and their applications.</p>","PeriodicalId":10979,"journal":{"name":"Current stem cell research & therapy","volume":"18 3","pages":"347-379"},"PeriodicalIF":2.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9485458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MSCs (mesenchymal stromal/stem cells) are multipotent stem cells present in a wide range of fetal, embryonic, and adult tissues. They are the progenitors of a variety of specialized cells and are considered crucial tools in tissue engineering. MSCs, derived from various tissues, including cord blood, placenta, bone marrow, and dental tissues, have been extensively examined in tissue repair, immune modulation, etc. Increasing the vitality of MSCs and restoring cellular mechanisms are important factors in treatment success. Oxidative stress harms cellular molecules such as DNA, proteins, and lipids due to the overproduction of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in cells and tissues or insufficiency of antioxidant systems that can inactivate them. Oxidative stress has a close link with inflammation as a pathophysiological process. ROS can mediate the expression of proinflammatory genes via intracellular signaling pathways and initiate the chronic inflammatory state. At the same time, inflammatory cells secrete a large number of reactive species that cause increased oxidative stress at sites of inflammation. In inflammatory diseases, the differentiation of stem cells and the regenerative and wound healing process can be affected differently by the increase of oxidative stress. Recent studies have indicated that dental pulp stem cells (DPSCs), as a resource of adult stem cells, are an attractive option for cell therapy in diseases such as neurological diseases, diabetes, cardiological diseases, etc., as well as its treatment potential in pulp inflammation. The future of oxidative stressinflammation cycle and/or ageing therapies involves the selective elimination of senescent cells, also known as senolysis, which prevents various age-related diseases. Most pathologies are implicated on the effects of ageing without exerting undesirable side effects.</p>","PeriodicalId":10979,"journal":{"name":"Current stem cell research & therapy","volume":"18 5","pages":"641-652"},"PeriodicalIF":2.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9492195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intervertebral disc degeneration (IVDD) is one of the leading causes of low back pain, which is most often related to patient morbidity as well as high medical costs. Patients with chronic IVDD often need surgery that may sometimes lead to biomechanical complications as well as augmented degeneration of the adjacent segments. Moreover, treatment modalities like rigid intervertebral fusion, dynamic instrumentation, as well as other surgical interventions are still controversial. Mesenchymal stem cells (MSCs) have exhibited to have immunomodulatory functions and the ability to differentiate into cartilage, making these cells possibly an epitome for IVD regeneration. Transplanted MSCs were able to repair IVDD back to the normal disc milieu via the activation of the generation of extracellular matrix (ECM) proteins such as aggrecan, proteoglycans and collagen types I and II.
