(Submitter supplied) How developmental programs reactivate in regeneration is a fundamental question in biology. We addressed this question through the study of Wound Induced Hair follicle Neogenesis (WIHN), an adult organogenesis model where stem cells regenerate entirely new hair follicles de novo following deep wounding. The exact mechanism is uncertain. Here we show that self-noncoding dsRNA activates the anti-viral receptor TLR3 to induce intrinsic retinoic acid (RA) synthesis in a gradient that predicts new hair follicle formation after wounding in mice. more...

(Submitter supplied) Mice were wounded and measured for regeneration starting 4 days after wound closure with simultaneous measurement of hair follicle neogenesis and biopsing. At each time point, RNA was collected from one mouse with high number of regenerated follicles and one without regenerated follicles.

(Submitter supplied) In a rare example akin to organogenesis in adult mammals, large wounds in mice lead to de novo morphogenesis of hair follicles. It is still not fully clear what controls this process, known as Wound Induced Hair Neogenesis (WIHN). In other tissues, prostaglandin E2 (PGE2) is an important effector of regeneration and has been shown to stimulate the Wnt/beta-catenin pathway, which in turn is known to control WIHN. more...

(Submitter supplied) Mammalian injury responses are characterized by fibrosis and scarring rather than the functional regeneration observed in other phyla. Limited regenerative capacity in mammals could reflect a loss of pro-regeneration programs or active suppression by genes functioning akin to tumor suppressors. To uncover programs governing regeneration in mammals, we investigated Wound Induced Hair Neogenesis (WIHN), a rare example of regeneration in adult mammals1,2. more...

(Submitter supplied) Environmental factors that enhance regeneration are largely unknown. We hypothesized that skin bacteria modulate regeneration. Here, we assessed low, medium, and high levels of bacterial burden in Wound Induced Hair follicle Neogenesis (WIHN), a rare adult organogenesis model. WIHN levels and stem cell markers indeed correlated with bacterial counts, being lowest in germ free (GF), intermediate in conventional specific pathogen free (SPF), and highest even in mice infected with pathogenic Staphylococcus aureus. more...

(Submitter supplied) Tissue regeneration is a process that recapitulates the molecular and mechanical aspects of development and evolution. We use the wound-induced hair neogenesis (WIHN) model to investigate the mechanical and molecular responses of the laboratory (Mus) and African spiny (Acomys) mice. Laboratory and spiny mice showed an opposite trend of spatiotemporal morphogenetic field for WIHN during wound healing, and wound stiffness gradient across the whole wound bed predicated pattern of hair formation. more...

(Submitter supplied) Stem cells upended from their niche upon injury display lineage plasticity, a transient multi-lineage state essential for tissue repair. Employing high-throughput approaches and three-dimensional cultures of hair follicle stem cells (HFSCs), we investigate the signals that govern the transition between homeostatic regeneration and lineage plasticity. We identify retinoic acid (RA) as a master orchestrator of HFSC behavior during these two processes. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived skin transcriptome profiling (RNA-seq) to determine pathways and networks dependent on retinoic acid during skin development. Methods: Skin mRNA profiles of embryonic day E16.5 wild-type (WT) and Cyp26b1 knockout (Cyp26b1−/−), and of control and of dermal and epidermal skin fractions of Engrailed1cre;Cyp26b1f/- (En1cre;Cyp26b1f/-) conditional knockout mice were generated by deep sequencing, in duplicate, using Illumina HiSeq2000. more...
