Abstract: In autoimmune illnesses like Rheumatoid Arthritis (RA), the synovium is constantly inflamed, and joints are ruptured. It is becoming increasingly clear that stem cells, especially notably mesenchymal stem cells (MSCs) and microRNAs (miRNAs), play important roles in the onset and amelioration of RA. There is mounting evidence from both animal and human studies that suggests a potentially safe and effective method to treat RA and other intractable diseases by reducing chronic inflammation and spurring tissue regeneration through the transplantation of multipotent adult stem cells, such as mesenchymal stromal/stem cells. To control gene expression, which impacts immune cell differentiation and inflammatory pathways, microRNAs (miRNAs) are crucial, even though MSCs can self-renew and modify inflammatory reactions. The pathophysiology of RA is marked by the dysregulation of immunological responses and the proliferation of fibroblast-like synoviocytes, which are linked to the aberrant expression of specific microRNAs (miRNAs). This study mainly aims to examine the therapeutic implications of these microRNAs (miRNAs) in relation to RA, as they can function as diagnostic and prognostic indicators. This study explores the functions of microRNAs (miRNAs) and stem cells in rheumatoid arthritis (RA), drawing attention to the relevance of these biological processes and the potential for creating novel therapeutic strategies to improve patient outcomes.
