Mammosphere Formation

Cancer stem cells (CSCs) exhibit self-renewal activity and give rise to other cell types in tumors. Due to the infinite proliferative potential of CSCs, drugs targeting these cells are necessary to completely inhibit cancer development. The β-lapachone (bL) compound is widely used to treat cancer development; however, its effect on cancer stem cells remain elusive. Thus, we investigated the effect of bL on mammosphere formation using breast-cancer stem-cell (BCSC) marker-positive cells, MDA-MB-231. MDA-MB-231 cells, which are negative for reduced nicotinamide adenine dinucleotide phosphate (NAD(P)H):quinone oxidoreductase (NQO1) expression, were constructed to stably express NQO1 (NQO1 stable cells). The effect of bL on these cells was evaluated by wound healing and Transwell cell-culture chambers, ALDEFLUOR assay, and mammosphere formation assay. Here, we show that bL inhibited the proliferative ability of mammospheres derived from BCSC marker-positive cells, MDA-MB-231, in an NQO1-dependent manner. The bL treatment efficiently downregulated the expression level of BCSC markers cluster of differentiation 44 (CD44), aldehyde dehydrogenase 1 family member A1 (ALDH1A1), and discs large (DLG)-associated protein 5 (DLGAP5) that was recently identified as a stem-cell proliferation marker in both cultured cells and mammosphered cells. Moreover, bL efficiently downregulated cell proliferation and migration activities. These results strongly suggest that bL could be a therapeutic agent for targeting breast-cancer stem-cells with proper NQO1 expression.

Due to the infinite proliferative potential of CSCs, drugs targeting these cells are necessary to completely inhibit cancer development. beta-lapachone (bL) has been widely used to treat cancer development, but its effect on cancer stem cells remain elusive. Thus, we investigated the effect of bL on mammosphere formation using breast cancer stem cell (BCSC) marker positive cells, MDA-MB-231. Methods: MDA-MB-231 Cells, which is negative for NQO1 expression, was constructed to stably express NQO1(NQO1 stable cells) to see the effect of bL. The effect of bL on cells were evaluated by wound healing and Transwell cell culture chambers, and ALDEFLUOR assay. Results: Here, we show that bL inhibited the proliferative ability of mammosphere derived from BCSC marker-positive cells, MDA-MB-231, in an NQO1-dependent manner. bL treatment efficiently downregulated expression level of BCSC markers CD44, ALDH1A1, and DLGAP5 that recently identified as a stem cell proliferation marker in both cultured cells and mammosphered cells.

: Mesenchymal stem cells because of its high proliferation, differentiation, regenerative capacity, and ease of availability have been a popular choice in cytotherapy. Mesenchymal Stem Cells (MSCs) have a natural tendency to home in a tumor microenvironment and acts against it, owing to the similarity of the latter to an injured tissue environment. Several studies have confirmed the recruitment of MSCs by tumor through various cytokine signaling that brings about phenotypic changes to cancer cells, thereby promoting migration, invasion, and adhesion of cancer cells. The contrasting results on MSCs as a tool for cancer cytotherapy may be due to the complex cell to cell interaction in the tumor microenvironment, which involves various cell types such as cancer cells, immune cells, endothelial cells, and cancer stem cells. Cell to cell communication can be simple or complex and it is transmitted through various cytokines among multiple cell phenotypes, mechano-elasticity of the extra-cellular matrix surrounding the cancer cells, and hypoxic environments. In this article, the role of the extra-cellular matrix proteins and soluble mediators that acts as communicators between mesenchymal stem cells and cancer cells has been reviewed specifically for breast cancer, as it is the leading member of cancer malignancies. The comprehensive information may be beneficial in finding a new combinatorial cytotherapeutic strategy using MSCs by exploiting the cross-talk between mesenchymal stem cells and cancer cells for treating breast cancer.
