Introduction:
Mesenchymal stem cells (MSCs) are revolutionizing regenerative medicine with their ability to self-renew and differentiate into various cell types. These multipotent cells, found in bone marrow, adipose tissue, and other sources, are already in clinical trials for treating orthopedic, cardiovascular, and autoimmune conditions. Understanding MSC stemness—their capacity to remain undifferentiated and maintain therapeutic properties—is crucial for advancing their medical applications.

Key Findings on MSC Stemness:
- MSCs can differentiate into chondrocytes, osteocytes, and adipocytes, making them valuable for tissue engineering.
- Their immunoprivileged nature allows for allogeneic transplantation without rejection concerns.
- MSCs experience replicative senescence after multiple passages, reducing their therapeutic effectiveness over time.
- The MSC niche—a microenvironment that maintains their undifferentiated state—plays a key role in preserving stemness.
Factors Influencing MSC Stemness:
Hypoxia and Niche Microenvironment
- Culturing MSCs under hypoxic conditions enhances proliferation and preserves stemness-related gene expression (Drela et al.).
- 3D culture techniques mimic in vivo conditions, delaying senescence and improving differentiation potential (Cesarz & Tamama).
Molecular and Genetic Regulation
- Overexpression of NRF2 enhances MSC proliferation and osteogenic differentiation .
- CD49f (integrin subunit α6) modulates MSC behavior by activating PI3K/AKT and suppressing p53.
- Epigenetic regulation via BCOR affects osteo-dentinogenic potential, linking MSC function to genetic control .
Clinical Applications and Future Research:
MSCs are already being used in clinical settings for:
- Bone and cartilage regeneration.
- Liver transplantation support (Shi et al.).
- Graft-versus-host disease (GVHD) treatment (Introna et al.).
Despite promising results, challenges remain in standardizing MSC therapy, overcoming senescence, and identifying a definitive stemness marker. More research is required to unlock the full regenerative potential of MSCs.
