Basonuclin helps identify and track hair follicle development and cycling in mice.

This study observed that epidermal necrosis and keratinocytic ballooning are consistent histopathologic signs of monkeypox in skin lesions, reinforcing the diagnostic value of histopathologic and immunohistochemical analyses.

This study found that taurine uptake by isolated human hair follicles promoted hair survival and protected against TGF-β1-induced damage in an in vitro setting.

Calretinin identifies the companion cell layer in human hair follicles.

In this study, elevated mRNA levels for serine-rich ultra high sulfur proteins were observed during active hair growth phases in mice, particularly in the forming hair structures and upper skin layers.

This study found that morroniside enhanced hair follicle growth and transition through the Wnt/β-catenin signaling pathway in a mouse model, suggesting its potential as a treatment for hair loss.

This study found that high levels of human cytokeratin 16 expression in transgenic mice lead to skin lesions and altered keratinocyte structure, suggesting potential implications for human skin disorders and wound healing.

This study observed that testosterone metabolism and androgen receptor localization differ significantly across body sites, with beard hair follicles showing distinct characteristics compared to occipital scalp hair follicles.

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.

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

This study concludes that loose anagen hair can develop in adulthood and may be difficult to distinguish from telogen hair loss, with pathologic findings offering limited diagnostic insights.

This study observed that hair casts, seen in girls with tightly drawn hairstyles, may result from local circulatory disturbances and scalp inflammation.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

This study found that vimentin expression in the hair follicles of Inner Mongolian Cashmere goats is highest during the growth stage and localized to the outer root sheath, suggesting a role in hair cycle regulation.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

This study suggests that the inner root sheath plays a significant role in maintaining hair follicle homeostasis during the catagen phase's early stages.

This study found that the twisted hair shafts characteristic of pili torti may result from uneven outer root sheath cell development, leading to irregular hair shaft modeling and twisting.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This study suggests that Ecklonia cava, particularly its component dioxinodehydroeckol, may promote hair growth by enhancing dermal papilla and outer root sheath cell activity in culture and mice models.

This study found that loss of contact between the arrector pili muscle and the hair follicle bulge may explain why hair loss in male and female pattern baldness is largely irreversible, unlike in alopecia areata.

This study found that topical cilostazol promotes hair growth, enhances hair follicle activities, and may serve as a potential treatment for alopecia.

In this study, different donor and recipient site preparation techniques for melanocyte-keratinocyte suspension were associated with similar repigmentation outcomes in stable vitiligo, but efficacy varied by body site.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

In this study, researchers reported that CD34 expression in the isthmic region of canine hair follicles suggests a potential stem cell compartment in this area.

This study indicates that the OVOL1-OVOL2 axis may play a significant role in hair follicle differentiation and growth, potentially serving as therapeutic targets for hair disorders like alopecia and in the tumorigenesis of pilomatricoma.

This study found that in male androgenic alopecia, the androgen receptor coactivator ARA70/ELE1 exhibits differential expression patterns, suggesting its involvement in the condition.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This study reports that citrulline, uniquely found in the inner root sheath of hair follicles, can be specifically detected with the carbamido diacetyl reaction, resulting in a bright orange color.

This study suggests that PDGFA and BMP2 play a role in the hair follicle cycle in cashmere goats, with PDGFA particularly involved in activating the growth phase.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.
