Project description:We have used the slow cycling property, found in hair follicle stem cells, to look for LRCs in sweat glands as putative stem cells. Gene expression profiling allowed us to determine the common and unique genes expressed in SG LRCs and non-LRCs. This allowed us to probe for the signaling pathways active in this skin appendage as well as determine potential molecular markers of SG LRCs. Sweat gland label retaining cells (LRCs) and surrounding basal layer cells were isolated from K5TetOffTreH2BGFP mice after a 4 week chase with doxycycline and compared to the basal layer of the sole's epidermis in 2 independent experiments.

Project description:The epithelial lining of the small intestine is continuously renewed from a small number of stem cells including Lgr5 expressing crypt base cells that have been shown to be a rapidly cycling stem cell population in homeostasis. Alternative markers of intestinal stem cells have variously identified populations as rapidly cycling or quiescent with proposed roles for the latter as a parallel or reserve stem cell population. However, the exact nature of quiescent crypt cells remains unknown. Here by applying novel mouse models that permit their isolation and characterisation as label-retaining cells (LRCs), and for the first time performing lineage tracing from them, we show quiescent cells to be committed secretory precursors that are capable of recall to the stem cell state. We reveal LRCs to be a small subset of the rapidly cycling Lgr5 expressing population committed along the Paneth-enteroendocrine lineage. Significantly, after injury and subsequent regeneration they are clonogenic, as shown by both lineage tracing and organoid growth demonstrating that they can be recalled to the stem cell pool. These findings in establishing quiescent cells as an effective clonogenic reserve during injury provides a motivation for investigating their role in the maintenance of cancer growth following adjuvant treatment. Six age and sex (female) matched Cyp1a1-H2B-YFP mice ten days post βNF induction were used comparing three cell populations from each. Following epithelial isolation, single cell preparation and staining with anti-CD24 anitbody and UEA-1 lectin, 30,000 cells were flow sorted for each population: Paneth cells (Paneth) were defined as CD24+/UEA+, YFP-LRCs (YFPpos) as CD24+/UEA-/YFP+ and LCCs (YFPneg) as CD24+/UEA-/YFP-. Microarray expression comparison was then performed to identify unique markers of each population. RNA amplification and hybridisation was performed at the Paterson Institute, Manchester, UK, Microarray Facility using Nugen Ovation Pico WTA System for amplification and then hybridisation to a Mouse Exon 1.0 ST Array. Arrays were scanned using an Affymetrix GeneChip scanner 3000 running GCOS software.

Project description:Cells with slow proliferation kinetics that retain the nuclear label over long time periods – the label-retaining cells (LRCs) – represent multipotent stem cells in a number of adult tissues. Since the identity of liver LRCs (LLRCs) had remained elusive we utilized a genetic approach to reveal LLRCs in normal non-injured livers and characterized their regenerative properties in vivo and in culture. We found that LLRCs were located in biliary vessels and participated in the regeneration of biliary but not hepatocyte injury. In culture experiments the sorted LLRCs displayed an enhanced self-renewal capacity but a unipotent biliary differentiation potential. Transcriptome analysis revealed a unique set of tumorigenesis- and nervous system-related genes upregulated in LLRCs when compared to non-LRC cholangiocytes. We conclude that the LLRCs established during the normal morphogenesis of the liver do not represent a multipotent primitive somatic stem cell population but act as unipotent biliary progenitor cells.

Project description:Identification of defined cell populations with stem/progenitor properties is key for our understanding of prostate development and tumorigenesis. Prior studies have provided strong evidence of the existence of prostate luminal progenitors, but their identity and functional properties remains unknown. Using an unbiased novel bigenic mouse model to specifically earmark, prospectively isolate, and functionally characterize the quiescent stem-like cells, we identify a label-retaining cell (LRC) population in the mouse prostate luminal cell layer as candidate luminal progenitors. Through comprehensive molecular and biological characterizations, we show that these luminal LRCs exhibit relative dormancy with significant enrichment in the mouse proximal prostate, display bipotent potential in both in vitro organoid formation and the in vivo prostate regeneration assay, express a stem/progenitor gene signature with resemblance to aggressive prostate cancer. Importantly, these luminal LRCs maintain a lower level of Ar expression, are androgen-independent, and resist castration in vivo. Furthermore, analysis of phenotypic markers by immunefluorescent staining reveals heterogeneity within luminal progenitor cell pool. Collectively, our studies establish luminal LRCs as progenitors that may serve as a cellular origin for castration resistant prostate cancer.

Project description:Sweat glands play a fundamental role in thermal regulation in man, but the molecular mechanism of their development remains unknown. To initiate analyses, we compared the model of Eda mutant Tabby mice, in which sweat glands were not formed, to wild-type mice. We inferred developmental stages and critical genes based on observations at 7 time points spanning embryonic, postnatal and adult life. In wild-type footpads, sweat gland germs were detected at E17.5. The coiling of secretory portions started at postnatal day 1 (P1), and sweat gland formation was essentially complete by P5. Consistent with a controlled morphological progression, expression profiling revealed stage-specific gene expression changes. Similar to the development of hair follicles the other major skin appendage controlled by EDA sweat gland induction and initial progression was accompanied by Eda-dependent up-regulation of the Shh pathway. During the further development of sweat gland secretory portions, Foxa1 and Foxi1, not at all expressed in hair follicles, were progressively up-regulated in wild-type but not in Tabby footpads. Upon completion of wild-type development, Shh declined to Tabby levels, but Fox family genes remained at elevated levels in mature sweat glands. The results provide a framework for the further analysis of phased downstream regulation of gene action, possibly by a signaling cascade, in response to Eda. This SuperSeries is composed of the SubSeries listed below.
