This research explores the use of serial block-face scanning electron microscopy to model the complex architecture of sheep wool fibres, focusing on the role and distribution of para- and ortho-cortical cells in determining wool curliness, though the mechanism remains unclear.

This study observed that the thinning and structural abnormalities in monilethrix-affected hair occur at the internodes due to possible periodic dysfunction of the hair matrix, particularly in the cortex.

This study re-examined the structure of lanceolate endings in rat vibrissae, suggesting that their apical cones may function as a transducer site for detecting hair movements.

Touch domes in human skin are complex sensory structures not directly linked to hair.

This study presents an improved reference genome for the African spiny mouse, which may aid in understanding its tissue regeneration at the molecular level.

This study developed a portable electrospinning device that mimics hair for cosmetic thickening in a mouse model, showing performance comparable to benchtop models with added safety and cost benefits.

This study suggests that ultra-fine powders of steamed and lyophilized mature silkworms may have enhanced pharmacological effects compared to fine powders, possibly due to their smaller particle size.

This study observed that daily selenium sulfide shampoos successfully removed fungal spores hidden beneath the hair cuticle in patients infected with ectothrix Microsporum canis.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

This study characterized proteins in hair-follicle and hair tissue, identifying similar protein types but with notable quantitative differences, which may reveal aspects of keratin protein synthesis.

In this study, researchers used single-cell RNA sequencing to map the hair follicle microenvironment in fine-wool sheep, identifying specific cell types and gene expressions that influence wool fiber diameter, with dermal papilla cells playing a significant role in hair follicle development.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

In this study, researchers found that circulating exosomes isolated from the plasma of Xinji fine-wool and small-tailed Han sheep influenced hair growth characteristics in mice, altering follicle and hair shaft diameters, and affecting hair follicle development and melanin synthesis.

This study developed microfluidic-assisted GelMA-MSC/HAD-EPC microspheres that efficiently generated hair follicles in nude mice, suggesting a promising strategy for advancing hair-regenerative medicine.

This study used multiphoton microscopy to successfully visualize rabbit skin microstructure, highlighting its noninvasive potential for future skin research related to diseases and wound healing.

This study using an apertureless scanning near-field optical microscope found that dye restricted to hair's periphery remains mainly on the surface and in the endocuticle.

This review highlights the light microscopic features of various infectious and non-infectious hair conditions and reports no new clinical results.

In this study, researchers showed that multiphoton microscopy with fluorescent protein tagging enables single-cell imaging and tracking in live transgenic mice, offering new insights into cell dynamics in stem cell research compared to traditional histological methods.

In this study, researchers explored the heterogeneity of pigment cells in the human scalp anagen hair follicle bulb and discovered unexpected subpopulations of melanocytes, including immature SOX10-negative cells, highlighting potential non-melanogenic roles or transitional migratory functions that require further investigation.

This study found that ATP synthases and the mitochondrial gene COX2 play a key role in determining the size of skin appendages in hedgehogs and mice by influencing energy metabolism and cell proliferation.

The hair follicle structure is more complex than thought, with new findings on protein formation.

This study found that the weak tensile strength of pili torti hair may result from loose keratin intermediate filaments due to abnormalities in disulfide bonds.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

This study shows that multiphoton microscopy can non-invasively distinguish scarring from non-scarring alopecia by identifying specific morphological features in hair follicle structures.

This study found that nanoemulsions of different sizes vary in their ability to penetrate skin layers, with smaller sizes aiding transdermal delivery and potential applications in transcutaneous immunization.

This study found that intermediate filaments and matrix proteins in presumptive hair shaft cells are synthesized sequentially, identifying a new polypeptide component that changes during hair cell differentiation.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.
