👉 Promycelial cells, also known as mesenchymal stem cells (MSCs), are a type of multipotent stem cell that can differentiate into various types of cells in the body. These cells have the ability to become either an osteoblast or an osteoclast depending on their differentiation program. They can also be found in bone marrow, and are involved in the healing process of bones, cartilage, and tendons.
