This study introduces a method for determining the orientation of collagen fibers in skin by analyzing the anisotropic shape of hair pores, which may aid in skin grafting procedures.

This review discusses the effects of vacuum massage on skin structures and concludes that there is insufficient evidence for its efficacy in treating burn scars, suggesting more research is needed on its potential benefits and mechanisms.

This study found that topical application of TGF-β mimic promoted enhanced wound healing and tissue regeneration in mice, suggesting its potential as a therapeutic option for improving wound healing.

This review derived guidelines for scalp surgery suggesting improved outcomes when avoiding neurovascular structures, preserving tissue integrity, and maintaining hair direction, but it reports no new clinical results.

This study found that Frizzled genes Fzd3 and Fzd6 are redundantly involved in controlling hair follicle polarity in mice, but operate through distinct mechanisms, highlighting their complex role in hair orientation.

This study presents a bioprinter-based method for creating scalable, automated hair-inductive tissue grafts that showed improved hair shaft sprouting in mice by using suture guides to control orientation.

This study found that using a combination of ablative CO₂ fractional laser and fetal fibroblast transplantation significantly reduced scarring in mice, with long-term sphere-forming cultured fibroblasts producing scar appearances closest to normal skin.

The connective tissue around hair follicles changes structure throughout the hair cycle.

This study presents a novel, scalable method for preparing highly hair-inductive tissue grafts using a bioprinter, which enhances hair follicle regeneration in mice, although most hair shafts remained beneath the skin.

This study reports that using a hydrogel-based therapy that dynamically regulates reactive oxygen species helps achieve skin regeneration in infected wounds, promoting organized dermal architecture with improved hair follicle and blood vessel formation, rather than scar formation.

In this study, CD109 overexpression in transgenic mice led to reduced inflammation and improved collagen organization during wound healing without affecting wound closure.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.

This study reports that transplantation of an ESCs-collagen-chitin biomimetic membrane leads to successful in situ skin regeneration, including hair follicle cell proliferation and formation of dermatoglyphs, in nude mice with full-thickness skin defects.

This review discusses the role of collagen XVII in maintaining stem cell niches and its impact on skin aging and wound repair, without reporting new clinical results.

In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This review derived guidelines for scalp surgery suggesting improved outcomes when avoiding neurovascular structures, preserving tissue integrity, and maintaining hair direction, but it reports no new clinical results.

This study reported that a novel liposomal formulation, SP-bFGF-SF-LIP, enhanced bFGF stability and skin permeability, significantly improving hair follicle recovery and wound healing in a mouse model.

This study found that PHBV cocultured with epithelial and dermal cells might enhance early-stage wound healing by promoting wound closure and re-epithelization more effectively than PHBV/collagen.

This research found that hyaluronic acid increased cell proliferation and type I collagen more effectively than poly-L-lactic acid in both human fibroblast cultures and rat dermis.

This study found that a novel skin patch combining extracellular matrix and ciprofloxacin promotes advanced wound healing and skin regeneration in mouse models of infected wounds.

This study found that grafting split-thickness human skin onto nude mice produces scars that mimic hypertrophic scar characteristics in humans, offering a useful model for studying scar formation and treatments.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

This study identified collagen XXII as a novel extracellular matrix protein specifically present at tissue junctions, where it functions as a cell adhesion ligand for skin epithelial cells and fibroblasts.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This article discusses the role of estrogens in skin aging and reports no new findings; it highlights the potential of selective ER modulators to improve skin health without systemic side effects.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This review discusses the effects of estrogen on skin aging and highlights potential therapies, but reports no new clinical findings.

This review discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.
