In this study, researchers used atomic force microscopy to evaluate mechanical stiffness across different skin layers in six participants, finding the highest stiffness in the epidermis and lower stiffness as layers progress to subcutaneous tissue, enhancing understanding of skin's physical properties and aiding future research.

The researchers reported that using extenders during scalp reductions increased effectiveness by 30 to 86% and prevented "stretch-back" in subsequent procedures.

In this study, researchers identified the PLD-mGluR protein in primary mechanosensory terminals as the homomeric GluK2 kainate receptor, functioning purely metabotropically, which is suggested to be common to various sensory endings.

This study found that mature adipocytes can dedifferentiate into fibroblast-like cells, driven by PDGF and TGFβ signaling, which may play a role in wound repair and fibrosis.

Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.

This study demonstrated that ablation of individual somatostatin-expressing interneurons increased activity in nearby neurons of the mouse motor cortex during motor learning.

This abstract only contains a stylized text design and provides no research findings or clinical results.

This study found that the KrasG12D mutation alters ERK signal dynamics in hair follicle stem cells, leading to tissue deformation, and suggests a collective effect of mutant cells is necessary for disruption.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

In this study, researchers standardized the Koelle and Friedenwald technique as modified by Gomori to reliably demonstrate discrete enzyme localization around eyebrow hair follicles in humans.

A new reliable scale improves accuracy in measuring hair density and treatment response.

This study identified five master regulators that mediate molecular differences in hair follicle development and sexual dimorphism in the skin, providing insights into male pattern baldness and hair follicle donor dominance.

In this study, AFM-based indentation was used to assess mechanical properties of murine skin wounds at two healing stages, revealing that early wounds exhibit stiffer hyperproliferative epithelium compared to granulation tissue, and highlighting significant influences of surface roughness on tissue stiffness measurements.

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 found a significant positive correlation between hair thickness and growth rate, with a notably slower growth rate observed in men with male pattern hair loss compared to healthy controls.

This study found that the dermal sheath smooth muscle regulates hair follicle progenitor cell death during hair regression through mechanical signaling of the TGF-β pathway.

This report summarizes recent cases of the rare condition erythromelanosis follicularis faciei et colli to illustrate its varied clinical presentations.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.

This study found that endothelin-1 increases adhesion and chemotaxis of amelanotic melanocytes on fibronectin, laminin, and collagen IV, potentially through changes in the actin cytoskeleton.

In this study, ectoderm-targeted transgenic mice with glucocorticoid receptor overexpression exhibited multiple epithelial defects, suggesting the role of NF-kappaB and p63 dysfunction in ectodermal dysplasia syndromes.

People with an imbalance between their cognitive and emotional empathy have lower levels of the hormone oxytocin in their hair.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

This study found that humans have a much higher eccrine gland density than chimpanzees and macaques, suggesting a unique evolutionary path for human skin features.

This study evaluated the efficacy of various skin graft types for burn injury healing, finding that xenografts had the highest repigmentation rate (87.50%), while device-facilitated autologous skin cell transplantation showed outstanding efficacy in reepithelialization, highlighting its potential in clinical practice.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

In this study, researchers found that human fingerprint ridges are formed through a modified hair follicle developmental process and spatial patterns influenced by specific signaling pathways.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

This study found that human hair follicles demonstrated a dose-dependent response to light in an ex vivo photoepilation model, which could predict the clinical efficacy and permanency of light-based hair removal devices.

This study found that mouse embryoid bodies adhered quickly and differentiated efficiently into cardiomyocytes on negatively charged poly(sodium p-styrene sulfonate) hydrogels, similar to their behavior on gelatin-coated polystyrene.
