(Submitter supplied) Global expression analysis of neural crest-like skin-derived precursors (SKPs) and Sox2-positive follicle dermal cells that SKPs originate from. In spite of the remarkable regenerative capacity of mammalian skin, an adult dermal stem cell has not yet been identified. Here, we provide evidence that SKPs, multipotent neural crest-like skin-derived precursors, represent an adult dermal stem cell. When transplanted into adult skin, SKPs can reconstitute the adult dermis, contribute to dermal wound-healing, home to a hair follicle niche, and instruct epidermal cells to make hair follicles. more...

Analysis of primary passage neonatal skin-derived precursors (SKP) and Sox2-positive hair follicle dermal cells from which SKPs derive. SKPs and Sox2+ dermal precursors share similar function and transcriptional profile. Results provide insight into potential role of SKPs as adult dermal stem cells.

(Submitter supplied) Skin-derived precursors (SKPs) are multipotent dermal stem cells that reside within a hair follicle niche and that share properties with embryonic neural crest precursors. Here, we have asked whether SKPs and their endogenous dermal precursors originate from the neural crest or whether, like the dermis itself, they originate from multiple developmental origins. To do this, we used two different mouse Cre lines that allow us to perform lineage tracing: Wnt1-cre, which targets cells deriving from the neural crest, and Myf5-cre, which targets cells of a somite origin. more...

(Submitter supplied) To assess if Hedgehog (Hh) responding cells in the skin have a unique expression profile, isolated keratinocytes that express the Hh response gene Gli1 were collected by FACS and their gene expression was compared to sorted CD34-expressing cells from the middle bulge region of the hair follicle and to cells from the interfollicular epidermis (IFE) by hybridization of isolated RNA to gene expression microarrays.

(Submitter supplied) We performed single-cell RNA seq on C57/BL6 mouse back skin at E13.5, E16.5, and P0 to study embryonic hair follicle development. We analyzed 15,086 single cell transcriptome profiles from E13.5, E16.5 and newborn mice (postnatal day 0, P0) dorsal skin cells across hair follicle induction, organogenesis, cytodifferentiation stage. Based on t-distributed Stochastic Neighbor Embedding (tSNE) clustering, we identified 14 cell clusters from skin cells and delineated their cell identity gene expression profile. more...

(Submitter supplied) Different types of hair follicles can be found in the skin of mice. It is believed that the signals that control hair follicle differentiation arise from cells in a structure called the dermal papilla. Understanding the nature of those signals is of interest for the biology of the normal tissue. We have developed a technique for isolation of dermal cells by enzymatic digestion of intact skin. We have identified two subpopulations of cells that can be separated by FACS. more...

(Submitter supplied) We developed a Tet-inducible system to express deltaNp63alpha isoform under the control of keratin 5 promoter. Transgenic mice, which were Bigenic (BG) developed a severe skin phenotype with abnormal keratinocyte differentiation and defects in hair follicle development and cycling. Skin samples from transgenic animals and wild type animals were analyzed for global transcriptome changes.

(Submitter supplied) Using Tbx18Cre to target embryonic DP precursors, we ablate Sox2 early and efficiently, resulting in diminished hair shaft outgrowth. Transcriptional profiling of Sox2 null DPs reveals increased Bmp6 and decreased Bmp inhibitor Sostdc1, a direct Sox2 transcriptional target.

(Submitter supplied) Mouse hair follicles undergo synchronized cycles. Cyclical regeneration and hair growth is fueled by hair follicle stem cells (HFSCs) and transit-amplifying cells (TACs). We used ChIP-seq to unfold genome-wide chromatin landscapes of H3K27ac and Med1 to identify super-enhancers and dissect their biological relevance in cell identity and plasticity of HFSCs in vivo and in vitro.

(Submitter supplied) We report downstream gene expression changes in stem cells of the adult mouse hair follicle upon conditional ablating of the transcription factor Forkhead Box C1 transcription factor (FOXC1). Hair follicles undergo cycles of rest (telogen; Tel) and regeneration (anagen; Ana). As such, we performed our analysis on these two different stages of hair follicles.

Bulk RNAseq samples were prepared from porcine cells, at least 500ng of RNA was extracted from sorted LGR5-GFP-high or LGR5-GFP-negative populations. more...

(Submitter supplied) A major challenge in delineating molecular and cellular events that precede appendage morphogenesis stems from the inability to distinguish quantitative molecular differences between cells that lack histological distinction. The hair follicle (HF) dermal condensate (DC) is a cluster of cells critical for HF development and regeneration. Events that presage emergence of this distinctive population are poorly understood. more...

(Submitter supplied) In homeostasis of adult vertebrate tissues, stem cells are thought to self-renew by infrequent and asymmetric divisions that generate another stem cell daughter and a progenitor daughter cell committed to differentiate. This model is based largely on in vivo invertebrate or in vitro mammal studies. Here we examine the dynamic behaviour of adult hair follicle stem cells in their normal setting by employing mice with repressible H2B-GFP expression to track cell divisions and Cre inducible mice to perform long-term single cell lineage tracing. more...

(Submitter supplied) Dermal lymphatics form a network that connects all the hair follicles in skin and localize in proximity to the Hair Follicle Stem Cell. RNA sequencing analyses of isolated dermal lymphatics at two different time points of the hair follicle cycle (P55 and P70) indicate the existence of dynamic signaling networks associated with lymphatic remodeling, immune trafficking, and HF signaling.

(Submitter supplied) Tissue homeostasis requires the balance of growth by cell production and regression through cellular loss. In the hair cycle during follicle regression, the niche traverses the skin through an unknown mechanism to reach the stem cells and prime regeneration. Here, by cell specific ablation and intravital imaging in live mice, we identify the follicle-lining dermal sheath as the key driver of tissue regression and niche relocation via smooth muscle contractile machinery that generates centripetal constriction force. more...
