Researchers in Lithuania have demonstrated that extracellular vesicles derived from menstrual blood stromal cells can stimulate the repair of cartilage, offering a potential path toward a cell-free therapy for osteoarthritis.
The findings, published in the journal Scientific Reports, were developed by a team of scientists from the fields of chemistry and biomedicine, including Dr. Ilona Uzielienė of the Kaunas University of Technology (KTU) Faculty of Chemical Technology.
Addressing Osteoarthritis
Osteoarthritis affects more than 600 million people globally. Data indicates that approximately 60% of those living with the condition are female, and around 73% are over the age of 55.
The prevalence of the disease is expected to increase due to factors such as rising obesity rates, an increase in injuries, and aging global populations.
Current clinical treatments primarily focus on managing inflammation and pain. However, no existing treatments can reverse or halt the degeneration of cartilage.
The Role of Menstrual Blood-Derived Cells
Regenerative medicine utilizes tissue engineering and stem cell technology to restore the function of human organs and tissues. Within this field, cells derived from menstrual blood have emerged as a promising alternative to bone marrow cells.
According to Dr. Uzielienė, menstrual blood is a naturally shed biological material, making its collection simple and non-invasive. This stands in contrast to the invasive procedures required to collect bone marrow.
These specific cells are naturally designed to secrete molecules that promote the regeneration of the uterine lining every month, making them an attractive source for regenerative medicine where accessibility and safety are priorities.
Findings on Extracellular Vesicles
The study focused on extracellular vesicles (EVs) derived from menstrual blood-derived mesenchymal stromal cells. These particles act as paracrine factors that can influence other cells.
The researchers found that these factors possess stimulatory effects on chondrogenesis in vitro and can diminish the degradation of articular cartilage during the progression of osteoarthritis.
What surprised us most was that the therapy worked even in cartilage cells from older postmenopausal women, whose natural regenerative capacity is already greatly reduced

Implications for Future Therapy
The use of these derived particles paves the way for a cell-free therapy. By utilizing the secreted vesicles rather than the cells themselves, researchers aim to create a treatment that can stimulate cartilage repair without the complexities of cell transplantation.
The study suggests that paracrine factors secreted by menstrual blood-derived stem cells (MenSCs) may serve as a promising therapeutic approach for the protection and repair of cartilage tissue.
