Source: Therapeutic effect of mesenchymal stem cells and their derived exosomes in diseases, Molecular Biomedicine, 4 Jun 2025. Summary written by Future Health GCC.
What this is
This is a scientific review published in Molecular Biomedicine in June 2025. It looks at five years of research on mesenchymal stem cells (MSCs) and exosomes, the tiny packages these cells release, as possible treatments for disease.
The cells and their exosomes
MSCs can be collected from several tissues, including bone marrow, fat (adipose) tissue, the umbilical cord and the placenta. They are of interest because they multiply well, travel to injured areas and are less likely to trigger rejection.
Much of their effect seems to come from the signals they send to surrounding cells. Exosomes are one way they do this: very small particles, carrying proteins and genetic material, that can calm inflammation and support repair. Researchers are studying whether exosomes could offer some of the benefits of the cells without transplanting the cells themselves.
What the review found
The authors describe three main ways MSCs and their exosomes appear to work: sending repair signals, calming the immune system and inflammation, and helping tissue regenerate. They review studies in heart and blood vessel disease, neurological conditions, autoimmune diseases and bone and joint disorders, some with encouraging results.
They also point out real challenges. Results vary widely between studies, cell quality and dose differ, the cells can lose activity in low-oxygen tissue, and possible long-term risks still need careful study.
How far along it is
Despite many clinical studies, these approaches are not yet in wide routine use, largely because of those inconsistent results. The authors call for more standardised methods and larger, well-designed trials.
What it means for families
The review explains why cells from sources such as the umbilical cord and placenta attract so much research interest. Exosome treatments in particular are still experimental, and this review does not show that they are ready for everyday use.
