Mesenchymal Stem Cells (MSCs) are a type of adult stem cell found in various tissues, including bone marrow, fat, and umbilical cord. They have the unique ability to differentiate into different cell types, such as bone, cartilage, and fat cells, making them important for tissue repair and regeneration. MSCs also play a role in the immune system by helping to modulate inflammation and support healing processes. Due to their regenerative properties, they are being studied for potential therapeutic applications in conditions like osteoarthritis, heart disease, and autoimmune disorders.
