The most common diseases are osteoarthritis (OA), rheumatoid arthritis (RA), neck and low back pain, tendinitis, carpal tunnel syndrome, fibromyalgia, and bone fractures [1,2,3]. Risk factors include occupation, way of life, and Nomegestrol acetate family history. However, since the risk of developing MSDs greatly raises with age, their prevalence raises with HSP90AA1 the rising average life expectancy [1]. The severity of MSDs ranges from slight pain and discomfort, which interferes with everyday activities, to total impairment of movement. For this reason, early analysis and treatment may help simplicity symptoms and improve long-term quality of life [4,5]. In particular, OA is defined as a chronic joint inflammatory disease that affects all joint cells of the musculoskeletal system, impacting mainly the hip, hand and knee articulations [6], including cells such as the infrapatellar excess fat pad and meniscus [7,8]. Individuals bearing OA usually display synovial swelling, calcified ligaments, subchondral bone sclerosis, osteophyte formation, and cartilage deterioration [9]. It is estimated that around 250 million people worldwide are suffering from OA [6]. Conversely, RA is an autoimmune inflammatory disorder characterized by synovial joint swelling and swelling, estimated to impact up to 1% of the population worldwide Nomegestrol acetate [10]. Both these MSDs are common causes of long term disability among the elderly population [11]. There is no remedy for MSDs OA and RA; the only available clinical options aim to reduce the effect of the most common symptoms caused by inflammation, especially pain [5,12,13]. These conditions typically progress towards long term joint damage, and treatments are intended to sluggish disease evolution. Currently, nonsteroidal anti-inflammatory medicines (NSAIDs) are frequently given to manage the overall disabilities caused OA [5]. This strategy can in some severe cases become coupled with surgery treatment to replace seriously damaged joints. However, considering the multiple complications for the patient associated with this approach, as well as its ineffectiveness in repairing cells function and movement, the need for novel and effective therapies is definitely clear [5]. New approaches to regenerating musculoskeletal cells are now growing. One rapidly-growing strategy to treat damaged cells, and diseases such as OA and RA, is definitely regenerative therapy; Nomegestrol acetate this has the advantage of being a multifactorial approach that combines biomaterial design mimicking the natural extracellular matrix (ECM) of the cells, these materials becoming loaded with autologous cells, bioactive molecules and growth factors to stimulate and improve the function of the prospective cells [14]. Immunoengineering is definitely a branch of regenerative medicine that focuses on the immune system and that seeks to modify the cellular response in order to facilitate cells reconstruction [15]. In particular, joint diseases such as OA and RA have been targeted with biomaterials and anti-cytokine treatments like a potential innovative therapy [16]. Considering the lack of performance of the currently given anti-inflammatory medicines in both OA and RA, the current task for experts and clinicians in the musculoskeletal regeneration field, is to develop and implement more effective therapies. This may Nomegestrol acetate occur through the use of biomaterials and the employment of genetic executive in order to modulate cell behavior. Within this scenario, the review explores the current research trends concerning cells regeneration in MSDs, focusing on Extracellular Vesicles (EVs) as future strategies for musculoskeletal system restoration through cell therapy, biomaterial technology, and immunoengineering. It focuses on the byproducts of Mesenchymal Stem/Stromal Cells (MSCs), more specifically EVs. 2. MSCs: Function and Mechanism of Action upon Tissue Damage MSCs or multipotent mesenchymal stromal cells, as recommended from the International Society for Cellular Therapy (ISCT) [17], are fibroblast-like adult multipotent progenitor cells that possess the ability to self-renew and differentiate in vitro into several cell types [18], mainly Nomegestrol acetate into osteoblasts, adipocytes and chondrocytes. MSCs can be harvested from several cells, including bone.
