(Submitter supplied) Mammalian epidermis consists of three self-renewing compartments: the hair follicle, sebaceous gland and interfollicular epidermis. We generated knock-in alleles of murine Lgr6, a close relative to the Lgr5 stem cell gene. Lgr6 was expressed in the earliest embryonic hair placodes. In adult hair follicles, Lgr6+ cells resided in a previously uncharacterized region directly above the follicle bulge. They expressed none of the known bulge stem cell markers. Prenatal Lgr6+ cells established the hair follicle, sebaceous gland and interfollicular epidermis. Postnatally, Lgr6+ cells generated sebaceous gland and interfollicular epidermis, while contribution to hair lineages gradually diminished with age. Adult Lgr6+ cells executed long-term wound repair, including the formation of new hair follicles. We conclude that Lgr6 marks the most primitive epidermal stem cell.

(Submitter supplied) Expression of deltaNB-cateninER allows the time and duration of B-catenin activation to be controlled precisely through the application of 4OHT. We have shown that B-catenin activation in adult mouse epidermis stimulates de novo hair follicles and the formation of a new bulge and melanocyte niche. We utilize Affymetrix Mouse Genome 430A 2.0 oligonucleotide arrays to investigate the differential regulation of RNA in skin from 7 week old female deltaNB-cateninER transgenic mice following 0, 1, or 7 days B-catenin activation in the epidermis. more...

(Submitter supplied) The Lhx2 transcription factor plays essential roles in morphogenesis and patterning of ectodermal derivatives, as well as in controlling stem cell activity. Lhx2 is expressed in the hair follicle (HF) buds, while in postnatal telogen HFs Lhx2+ cells reside in the stem cell-enriched epithelial compartments (bulge, secondary hair germ) and co-express selected stem cell markers (Sox9, Tcf4 and Lgr5). Lhx2+ cells represent the vast majority of cells in the bulge and secondary hair germ that proliferate in response to skin injury. more...

(Submitter supplied) Mouse skin cell lines in various stages of tumorigenesis were assayed for transcriptome-wide expression levels. We assessed gene expression levels in mouse skin cell lines representing immortalized keratinocytes, premalignant lesions, malignant squamous cell carcinomas, and malignant squamous cell carcinomas with spindle morphology. These tumors were overwhelmingly driven by Hras mutations. The cells themselves were derived from multiple mouse strains.

(Submitter supplied) 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.

(Submitter supplied) Tissue stem cells govern tissue regeneration and wound-repair. Tumors often hijack these normal cellular programs and exploit them for malignancy. Here, we identify such a phenomenon in skin, where stem cells of the epidermis and hair follicle remain faithfully restricted to fueling their own tissue during homeostasis. They lose lineage fidelity during tumorigenesis. Moreover, breakdown of stem cell lineage confinement – granting privileges associated with both fates – is not only a hallmark, but also obligatory for malignancy. more...

(Submitter supplied) MED1 (Mediator complex subunit 1) is expressed by human epidermal keratinocytes and functions as a coactivator of several transcription factors. To elucidate the role of MED1 in keratinocytes, we established keratinocyte-specific MED1-null (MED1epi-/-) mice using the K5Cre-LoxP system. To elucidate the mechanism(s) underlying abnormalities of keratinocytes derived from MED1epi-/- mice, we compared the gene expression patterns of MED1epi-/--derived keratinocytes with their wild type counterparts by microarray analysis.

In this study we used a microarray analysis to indentify differentially expressed genes in Foxi3 null epithelium compared to Foxi3 wt epithelium. We used E15.5 stage as the earliest time point when the Foxi3 null hair phenotype bacame obvious, to find out the most early consequences of Foxi3 ablation.

(Submitter supplied) Mechanisms of plasticity to acquire different cell fates are critical for adult stem cell (SC) potential, yet are poorly understood. Reduced global histone methylation is an epigenetic state known to mediate plasticity in cultured embryonic SCs and T cell progenitors. We used mouse hair follicle stem cells (HFSCs) at two different hair cycle stages (early anagen and late catagen) to compare the genome-wide changes in the levels of histone modification marks H3K4me3, H3K9me3, and H3K27me3.

(Submitter supplied) Continuous cell renewal in mouse epidermis is at the expense of a pool of pluripotent cells that lie in a well defined niche in the hair follicle known as the bulge. To identify mechanisms controlling hair follicle stem cell homeostasis, we developed a strategy to isolate adult bulge stem cells in mice and to define their transcriptional profile. We observed that a large number of transcripts are underexpressed in hair follicle stem cells when compared to non-stem cells. more...

(Submitter supplied) In this study, we defined a differentiation approach for guiding human pluripotent stem cells in to complex hair-bearing skin tissue, known as skin organoids. The primary goal of this single-cell RNA-sequencing analysis was to define the cellular composition of skin organoids, which we have shown using histology contain multiple embryonic cell lineages. The secondary goal was to determine whether skin organoids generated using different cell lines (WA25 hESCs and DSP-GFP hiPSCs) contain similar cell types.
