This study observed that using serial sectioning and d-PAS staining improved detection of Malassezia folliculitis, notably in lesions on the trunks of male patients.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This review discusses mesenchymal–epithelial interactions in hair follicle development and cycling, highlighting recent insights without reporting new experimental results.

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

In this study using diabetic rat models, the combination of AMD3100 and low-dose FK506 reduced wound healing time and improved microcirculation in diabetic foot ulcers, indicating a promising new systemic therapy.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

This study found that dermal fibroblast cultures, especially those with higher alpha-smooth muscle actin expression, can be used to produce skin-derived precursor cells, unlike human hair follicle dermal papilla cultures.

This study found that a high-energy shock wave can increase osteogenic activities in human mesenchymal cells, offering insights into potential therapeutic targets for trauma-induced heterotopic ossification.

This report explores the potential cellular origins of keratoacanthoma lesions on the oral mucosa, noting that it reports no new results.

In this study, flutamide at therapeutic doses caused significant histological changes in the testes and epididymis of adult albino rats, reducing androgen receptor immunoreactivity and increasing estrogen receptor immunoreactivity.

This study applied a new RGB trichrome stain to human skin samples, revealing distinct structural staining in normal tissues and potential proteoglycan-rich zones in hair follicles.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This study found that histomorphological evaluation of nail punch biopsies is useful for diagnosing various nail-related dermatoses, with psoriasis being the most common condition observed.

This review discusses the current knowledge on using special and immunohistochemical stains for diagnosing hair disorders, concluding that no stains are recommended for routine use in hair pathology.

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.
