Aim of Study:

One of the new methods that have promising results is the use of cell-derived microvesicles (MVs) to kill tumor cells. Given that MVs contain apoptotic materials, genes, and proteins, they can interfere with the fate of adjacent cells.

Materials and Methods:

In the present study, after adipose tissue-derived mesenchymal stem cells (AT-MSCs) isolation and characterization, MVs were derived from AT-MSCs and then characterized morphologically by standard error of the mean and size determination by DLS, and after that, the influence of MVs on human breast cancer cells (MCF-7) was investigated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium assay and apoptosis-related gene expression. The raw data were analyzed in SPSS.17 software.


The results indicated that MVs have a size range of 500-1500 nm, and the viability of MCF-7 was significantly decreased when treated by different concentrations of MVs and it was confirmed when apoptosis-related genes' expression level was measured by real-time reverse transcription polymerase chain reaction whereas demonstrated that apoptosis genes including Bax, P53, P21, and EP300 (2- ΔΔ CT) and ΔCT values were expressed significantly in MCF-7 treated by MVs higher than those nontreated, and decrease of Bcl-2 expression level in MVs-treated MCF-7 was also significant as an antiapoptosis-related gene.


Taking together, AT-MSC-derived MVs demonstrated anticancer or antitumoral properties on MCF-7 cells, and it could also be effective for other types of cancer cells.
