This study found that a skin-like structure can be generated in vitro by implanting early passage hair follicle bulb cells into collagen/chitosan porous scaffolds.

In this study, researchers found that hair follicle-like structures can be generated from collagen/chitosan porous scaffolds implanted with mouse hair follicle cells in vitro.

This review summarizes techniques like Raman spectroscopy, nanoindentation, and small-angle X-ray scattering to explore the biophysical interactions in collagen fibers, aiming to enhance understanding of fibroblast behavior and mechanisms involved in organ fibrosis and healing processes.

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.

This study presents a method using polarization-sensitive optical coherence tomography to accurately assess the depth of burn wound damage in the dermal collagen matrix, potentially improving diagnosis beyond traditional visual methods.

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 details the histological structure of the white domesticated pig's ear skin and discusses its relevance as a model for human dermatological research.

This study observed that the lower part of vibrissa hair roots in adult Wistar rats receives a richer blood supply and structural protection, compared to the upper part.

This study evaluated the effects of topical glucocorticoids on human skin using non-invasive imaging methods and observed changes such as alterations in skin layer thickness, keratinocyte size, and collagen and elastin signal intensity.

This chapter reviews the skin's structure and its clinical relevance, highlighting connective tissue diseases and the potential for novel treatments like protein, cell, or stem cell transfer, but reports no new findings.

This study found that rabbit skin histology revealed changes in collagen and elastic fibers after soaking, dehairing, and tanning processes, impacting fiber tightness and fur removal.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

This study reports that Ca 2+ binding alters the dynamics and surface properties of PKD-like domains in Clostridium histolyticum collagenases, enhancing their stability and potentially aiding in collagen-targeting vehicle development.

This article reviews the structure and function of the skin and its importance for understanding skin diseases, without providing new clinical results.

This article reviews over 1000 skin diseases affecting patients' quality of life and highlights the importance of understanding skin biology and pathology, but provides no new results.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

This study examined the subcutaneous structures in forehead creases using cadavers and observed that dense fibrous structures connecting the dermis to the frontalis muscle, as well as specific epidermal and dermal characteristics, may contribute to the formation of these creases.

This study found that systemic testosterone exposure in transgender individuals with XX genotype alters skin biology, increasing androgen and estrogen receptor-positive cells, collagen density, and fibronectin expression while reducing immune cells, which could affect surgical outcomes by promoting a male skin phenotype.
