N2 - It is known that exosomes are involved in the cancer development, including by increasing the motility of tumor cells and increasing their invasive potential. Since it is not clear how involved the exosomes associated with the blood cell surface are in the dissemination of the tumor process, this paper is devoted to assessing the level of tetraspanin-associated metalloproteinase ADAM-10 on the surface of plasma exosomes and total exosomes of blood of clinically healthy women (n = 30), patients with mastopathy (n = 28) and breast cancer (n = 32).

Using flow cytofluorimetry with antibodies against universal exosomal markers, it was found that CD9 and CD24-positive exosome subpopulations predominate in preparations of microvesicles from the blood of healthy women and tumor patients. A comparative analysis of the ADAM-10 level on the surface of plasma exosomes and total exosomes in the blood of healthy women and tumor patients showed the absence of significant differences in both microvesicle subpopulations, except for patients with luminal type breast cancer.
