Project description: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. Whole skin biopsies of wound scars were submitted for Affymetrix Exon arrays. 3 replicates of mice with high number of regenerated follicles, 3 replicates of mice with no regenerated follicles; each pair taken at a different date after wound closure.

Project description:Mice were wounded and skin samples of the scar collected on the day of wound closure. We compared Mixed mice (B6/FVB/SJL), a strain of high regeneration, versus C57bl mice, a strain of low regeneration. Whole skin biopsies of wound scars were submitted for Affymetrix Exon arrays. 4 mice each of 2 distinct strains of differing regeneration levels were collected.

Project description: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. Using bulk and single-cell RNA-seq analysis and K14-Cre-Twist1 transgenic mice, we identified the central role of the Twist1 pathway as the mediator of epidermal-dermal interaction and the emergence of periodic hair primordia. Lastly, we generated a Turing model with an underlying measure of stiffness to support a two-scale tissue mechanic model to explain the setup of a morphogenetic field from a wound bed (mm scale) or periodically arranged hair primordia from a morphogenetic field (μm scale). Delineating the common and distinct chemo-mechanical events during regenerative wound healing between laboratory and African spiny mice reveal its evo-devo advantages, which provide new perspectives for regenerative medicine.

Project description:The full complement of hair follicles is generated during embryogenesis. Normally, no new hair is created after this time. Large full thickness skin excision wounding can result in the generation of new hair in the adult. Placodes can be observed following complete reepithelialization at wound day 14. The events leading to hair neogenesis following wounding remain poorly understood. Late healing events (from wound day 10 to wound day 14) provide a possible window of induction for hair regeneration. We used microarrays to analyse changes in gene expression during late skin healing to provide candidates for factors involved in hair neogenesis following wounding. 6 week old C57Bl/6 mice received large full thickness skin excisions. Healing wound tissue was excised at wound day 10, 12 or 14 and analyzed for gene expression.

Project description:Wound Induced Hair Follicle neogenesis (WIHN) is a hair neogenesis phenomenon which occurred in the center of scar. Neonatal hair follicle are separated from the preexisting follicles by a hairless circular. We analysed the differentially expressed proteins between inner and outer area of scar at post-wound day 15 by iTRAQ technology.
