Abstract
Mesenchymal stem cells (MSCs) are adult stem cells that have the ability to self-renew
and differentiate into several cell lineages including adipocytes, chondrocytes, tenocytes,
bones, and myoblasts. These properties make the cell a promising candidate for regenerative
medicine applications, especially when dealing with sports injuries in the knee. MSCs
can be isolated from almost every type of adult tissue. However, most of the current
research focuses on MSCs derived from bone marrow, adipose, and placenta derived products.
Synovial fluid-derived MSCs (SF-MSCs) are relatively overlooked but have demonstrated
promising therapeutic properties including possessing higher chondrogenic proliferation
capabilities than other types of MSCs. Interestingly, SF-MSC population has shown
to increase exponentially in patients with joint injury or disease, pointing to a
potential use as a biomarker or as a treatment of some orthopaedic disorders. In this
review, we go over the current literature on synovial fluid-derived MSCs including
the characterization, the animal studies, and discuss future perspectives.
