This study revealed that basement membrane dynamics are crucial to hair follicle development, influencing progenitor cell behavior and cell division patterns in developing mouse hair follicles.

CD8+ T cells attack hair follicle stem cells, causing scarring and hair loss in Discoid Lupus.

This study found that topically applied melatonin exerts significant anti-aging effects on human scalp skin ex vivo, including increased SIRT1 expression and reduced mTORC1 pathway activity.

This study observed that pilose antler extract promoted hair growth in mice with androgenetic alopecia by stimulating the hair follicle growth cycle via the SHH/GLI pathway activation and BMP/Smad pathway suppression.

This study demonstrated that using a mass spectrometry imaging technique, researchers were able to visualize the incorporation of argan, avocado, and coconut oils into hair fibers, suggesting their potential in cosmetic and alopecia treatments by confirming oil absorption and fiber modification.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.

This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.

This review compiles existing research on infrared radiation's effects on human skin, noting both its potential harmful thermal impacts and encouraging therapeutic applications, but reports no new clinical results.

The study identified increased IL-24 expression in keratinocytes and fibroblasts exposed to particulate matter, contributing to skin aging by promoting conditions similar to age-related changes such as increased MMP1 expression and decreased type I collagen production.

This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

This review discusses the roles of various growth factors and cytokines in skin regeneration, highlighting their potential for future therapeutic development, and reports no new experimental findings.

This review discusses the genetic and metabolic factors influencing hair pigmentation, as well as conditions leading to hypo- or depigmented hair, and reports no new experimental findings.

This study explores the use of in silico methods to identify potential diagnostic biomarkers for primary cicatricial alopecia, revealing significant interactions among genes and proteins related to disease pathogenesis.

This review discusses the potential of ginseng and its metabolites for treating hair loss and reports no new clinical findings.

In this study, the researchers observed that post-radiation hair follicle repair in 3D architecture occurs through independent, long-range cell movements along the basal surface, resembling 2D healing processes.

This study found that manipulating both gene expression and matrix stiffness in mice can alter hair regeneration after skin wounding, highlighting key factors in regenerative biology.
