Abstract

The effects of stromal cell cultures isolated from breast cancer tissue on the differentiation and maturation of dendritic cells and proliferation of lymphocytes were studied in vitro. The derived cultures had the fibroblast-like morphology and carried mesenchymal markers CD73 and CD90 in the absence of epithelial (CD326, CD24) and macrophage (CD68) markers. The cells also expressed CD44, CD10, and CD29 and had low levels of HLA-ABC expression. Intracellular expression of fibroblast activation protein (FAP), tenascin C, and α-SMA indicated their activated state and stromal origin. Analysis of the functional properties of the cells revealed their ability to suppress differentiation of dendritic cells from monocytes, as well as the proliferation of T lymphocytes. However, they had no significant effect on DC maturation. The results demonstrate that fibroblasts in the tumor stroma of breast cancer may have a suppressive effect on important mechanisms of the adaptive immunity and can be involved in the process of tumor escape from the immunological control.

期刊介绍： Bulletin of Experimental Biology and Medicine presents original peer reviewed research papers and brief reports on priority new research results in physiology, biochemistry, biophysics, pharmacology, immunology, microbiology, genetics, oncology, etc. Novel trends in science are covered in new sections of the journal - Biogerontology and Human Ecology - that first appeared in 2005. World scientific interest in stem cells prompted inclusion into Bulletin of Experimental Biology and Medicine a quarterly scientific journal Cell Technologies in Biology and Medicine (a new Russian Academy of Medical Sciences publication since 2005). It publishes only original papers from the leading research institutions on molecular biology of stem and progenitor cells, stem cell as the basis of gene therapy, molecular language of cell-to-cell communication, cytokines, chemokines, growth and other factors, pilot projects on clinical use of stem and progenitor cells. The Russian Volume Year is published in English from April.
