Project description:During reproductive life, the human endometrium undergoes around 480 cycles of growth, breakdown and regeneration should pregnancy not be achieved. This outstanding regenerative capacity is the basis for women’s cycling and its dysfunction may be involved in the etiology of pathological disorders. Therefore, the human endometrial tissue must rely on a remarkable endometrial somatic stem cells (SSC) population. Here we explore the hypothesis that human endometrial side population (SP) cells correspond to somatic stem cells. We isolated, identified and characterized the SP corresponding to the stromal and epithelial compartments using endometrial SP genes signature, immunophenotyping and characteristic telomerase pattern. We analyzed the clonogenic activity of SP cells under hypoxic conditions and the differentiation capacity in vitro to adipogenic and osteogenic lineages. Finally, we demonstrated the functional capability of endometrial SP to develop human endometrium after subcutaneous injection in NOD-SCID mice. Briefly, SP cells of human endometrium from epithelial and stromal compartments display genotypic, phenotypic and functional features of SSC.

Finally, we demonstrated the functional capability of endometrial SP to develop human endometrium after subcutaneous injection in NOD-SCID mice. Briefly, SP cells of human endometrium from epithelial and stromal compartments display genotypic, phenotypic and functional features of SSC. Human tissue collection: Human endometrial biopsies were taken using a Pipelle catheter under sterile conditions (from 18 to 48 years) throughout the menstrual cycle. Epithelial and stromal separation: Epithelial and stromal fractions were isolated using an established protocol with modifications. Briefly, samples were carefully dissected and minced into 1-2mm fragments, and enzymatically digested in DMEM containing 10 mg/ml collagenase type IA. Stromal cells (single cells or small aggregates) and epithelial glands were separated on a size basis using gravity sedimentation and membrane filtration. Cell suspensions were treated with erythrocyte lysis solution and evaluation of cell viability was performed with Propidium Iodide (PI; 5 μg/ml). Hoechst 33342 labeling: Cells isolated from the endometrial epithelial and stromal fractions were resuspended in DMEM prewarmed at 37ºC and supplemented with 2% FBS and 10mM HEPES. The cell suspension was labeled in the same media with 5 μg/ml of Hoechst 33342 dye (Ho-33342), either alone or in combination with 100 μM verapamil (Vp), in a water bath at 37ºC for 90-120 minutes. Then, cells were centrifuged for 6 minutes at 4ºC, and were resuspended in cold HBSS supplemented with 2%FBS and 10mM HEPES. PI permits to exclude dead cells prior to the flow cytometric analysis and sorting. Isolation of human endometrial SP cells: Cells were analyzed and sorted by a MoFlo® jet-in-air high speed sorter. Excitation was performed with a water cooled Enterprise II ion laser which operated at the 351 nm and 488 nm wavelengths, and worked at 30 mW. Hoechst 33342 blue and red fluorescences were detected through 405/30 and 670/20 nm band-pass filters respectively, by measuring the signals on a linear scale. PI fluorescence was detected through a band-pass filter of 613/20 on a logarithmic scale. The gates for cell sorting were defined to collect live cells with a low Hoechst 33342 fluorescence (SP fraction), as well as live cells with a high Hoechst 33342 fluorescence (NSP fraction). Microarrays experiments: Endometrial tissue consisted in a total of 8 endometrial biopsies (epithelial (n=8) and stromal (n=8) endometrial cell suspensions, epithelial SP fraction (n=8) and stromal SP fractions (n=8) separately) which were pooled in pairs at the RNA levels. Four microarrays were analyzed per group.

Project description:Subpopulations of highly tumorigenic, drug resistant cancer stem-like cells play a key role in cancer recurrence and progression. Surprisingly, these aggressive cells can arise repeatedly de novo from bulk tumor cells independently of mutational events. We investigated whether transition to and from a cancer stem-like state is associated with epigenetic alterations, such as DNA methylation and chromatin accessibility. By Hoechst dye staining and FACS analysis, side population (SP) and non-side population cells were sorted from J82 cells. AcceSssIble assay by Infinium EPIC BeadArray platform was used to identify potential epigenetic driver genes in the process of SP /NSP phenotype plasticity. Genes with differential accessible promoter regions were overlapped with genes differentially expressed by HuEx array analysis. Oncomine and Basespace were adopted to explore the clinical relevance of the target genes.

Project description:Side population (SP) cells are identified based on their capacity to efflux of the fluorescent dye Hoechst 33342, and are enriched for hematopoietic stem cells (HSCs) in mammalian bone marrow. We recently demonstrated that SP cells were present in the teleost kidney, the main hematopoietic organ in teleosts, and were enriched for HSCs. In this analysis, to identify the regulated genes in teleost HSCs, gene expression analysis of zebrafish kidney SP cells were performed using the GeneChip Zebrafish Genome Array.

Project description:Melanoma remains the most lethal skin cancer, mainly because of high resistance to therapy. Side population (SP) cells are found in many types of cancer and are usually enriched in therapy-resistant as well as tumorigenic cells. Here, we identified a Hoechst dye-effluxing SP in a large series of human melanoma samples representing different progression phases. The SP size did not change with disease stage but was correlated with the prognostic “Breslow’s depth” in the primary (cutaneous) tumors. When injected into immunodeficient mice, the SP generated larger tumors than the bulk “main population” (MP) melanoma cells in two consecutive generations, and showed tumorigenic capacity at lower cell numbers than the MP. In addition, the SP reconstituted the heterogeneous composition of the human A375 melanoma cell line, and its clonogenic activity was 2.5-fold higher than that of the MP. Gene-expression analysis revealed upregulated expression in the melanoma SP (versus the MP) of genes associated with chemoresistance and anti-apoptosis. Consistent with these molecular characteristics, the SP increased in proportion when A375 cells were exposed to the melanoma standard chemotherapeutic agent dacarbazine, and to the aggravating condition of hypoxia. In addition, the SP showed enhanced expression of genes related to cell invasion and migration, as well as to putative (melanoma) cancer stem cells (CSC) including ABCB1 and JARID1B. ABCB1 immunoreactivity was detected in a number of tumor cells in human melanomas, and in particular in clusters at the invasive front of the primary tumors. Together, our findings support that the human melanoma SP is enriched in tumorigenic and chemoresistant capacity, considered key characteristics of CSC. The melanoma SP may therefore represent an interesting therapeutic target. Four primary melanomas (subtype SSMM) were dissociated into single cells. From each of these single cell suspensions, side population (SP) and bulk \main population\ (MP) cells were isolated based on their Hoechst-effluxing capability using fluorescence-activated cell sorting. Gene expression of SP cells is analyzed relative to the gene expression of the corresponding MP cells.
