Abstract (original English)
Breast cancer tissue is a heterogeneous cellular milieu comprising cancer and host cells. The interaction between breast malignant and non-malignant cells takes place in breast tumor microenvironment (TM), and has a crucial role in breast cancer progression. In addition to cellular component of TM, it mainly consists of cytokines released by tumor cells. The tumor-tropic capacity of mesenchymal stem cells (MSCs) and their interaction with breast TM is an active area of investigation. In the present communication, the interplay between the breast resident adipose tissue-derived MSCs (B-ASCs) and breast TM was studied. It was found that a distinct subset of B-ASCs display a strong affinity for conditioned media (CM) from two breast cancer cell lines, MDA-MB 231 (MDA-CM) and MCF-7 (MCF-CM). The expressions of several cytokines including angiogenin, GM-CSF, IL-6, GRO-α and IL-8 in MDA-CM and MCF-CM have been identified. Upon functional analysis a crucial role for GRO-α and IL-8 in B-ASCs migration was detected. The B-ASC migration was found to be via negative regulation of RECK and enhanced expression of MMPs. Furthermore, transcriptome analysis showed that migratory subpopulation express both pro- and anti-tumorigenic genes and microRNAs (miRNA). Importantly, we observed that the migratory cells exhibit similar gene and miRNA attributes as those seen in B-ASCs of breast cancer pat
