Bone Marrow Stromal Stem Cells in Tissue Engineering and Regenerative Medicine

Area of Science:

• Stem Cell Biology
• Regenerative Medicine
• Immunomodulation

Background:

• Bone marrow stromal stem cells (BMSCs) are adult multipotent stem cells.
• BMSCs possess the potential to differentiate into mesodermal lineages (osteocytes, adipocytes, chondrocytes).
• Historically recognized for therapeutic potential in tissue engineering and regenerative medicine.

Purpose of the Study:

• To review current clinical applications of bone marrow stromal stem cells.
• To discuss the therapeutic properties and limitations of BMSCs.
• To provide an overview of BMSC-based treatments.

Main Methods:

• Literature search of PubMed, Ovid, and Google Scholar databases.
• Keywords used: "stem cells", "tissue engineering", "tissue regeneration", "clinical trials".
• Clinical trials.gov was utilized to identify completed trials involving bone marrow-derived stem cells.

Main Results:

• BMSCs can directly participate in tissue regeneration and migrate to injury sites.
• They facilitate tissue repair through differentiation and paracrine mechanisms.
• BMSCs exhibit immunomodulatory capabilities, attenuating inflammatory and immune responses.

Conclusions:

• BMSCs are being explored for treating diverse conditions, including bone defects, graft-vs.-host disease, cardiovascular, autoimmune, metabolic, neurological, liver, and kidney diseases.
• Their therapeutic utility extends beyond direct differentiation to include paracrine signaling and immunomodulation.
• While promising, the clinical application of BMSCs also faces limitations that warrant further investigation.
