This study suggests that epithelial-derived pop-up keratinocytes (ePUKs) may improve regenerative medicine applications due to their specific phenotype and increased expression of proteins involved in regulating cellular movement and wound healing.

This study found that lineage-restricted loss of p63 in murine thymic epithelial cells resulted in severe thymic hypoplasia and absence of hair follicles, indicating p63's critical role in thymic and hair follicle development.

This study found that coculturing human hair follicle keratinocyte stem cells with dermal papilla cells increased expression of the hair-specific keratin 6hf gene, which requires β-catenin/lef-1 signaling for hair differentiation.

Wnt-10b helps skin cells develop into hair-related structures.

This study mapped the development of the human pilosebaceous unit in prenatal scalp skin using multi-modal analysis, finding that epithelial-mesenchymal interactions guide cellular fate and validated tissue-patterning through a hair-bearing skin organoid model.

This study reports for the first time on the expression patterns of Id2 and Id3 proteins in developing hair follicles, suggesting a significant role for these proteins in hair follicle development and epithelial-mesenchymal interactions.

This study found that loss of Apc due to K14-cre-mediated gene recombination in mice led to aberrant growth in ectodermally derived squamous epithelia, implicating its critical role in specifying epithelial cell fates during embryonic development.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This study found that manipulating Wnt/β-catenin signaling in embryonic mammary glands impacted their development, with high activity levels hindering branching and potentially redirecting cells toward hair follicle identity instead of mammary tissue.

This review article examines recent studies on the role of diverse immune cells in forming an active niche for hair follicles, offering new insights into hair growth and related diseases.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study developed a 3D engineered hair follicle model that mimics the native hair bulb and may aid in drug screening for hair growth therapies.

In this study, mice lacking the Mcpip1 gene in their myeloid cells did not develop SCC-like tumors but instead showed increased melanocyte activity and hair loss, indicating a distinct role for myeloid Mcpip1 in skin cancer development compared to keratinocyte Mcpip1.

This study observed that dermal dendritic cells migrate to the epidermis in mouse tail and back skin, correlating with changes in epidermal physiology like ortho- and parakeratosis.

This study found that RSPO1 mutations in patients with a 46XX disorder of sexual development contribute to impaired skin integrity and increased risk of squamous cell carcinoma in areas subject to friction.

This study found that inducing a leaky gut in mice led to increased gut permeability and decreased expression of protective genes, suggesting a potential link to alopecia areata.

This study suggests that linalool, a common allergen in personal care products, may contribute to frontal fibrosing alopecia pathogenesis by triggering immune responses and depleting hair follicle stem cells, especially in sensitized individuals.

In this study, the antibody A3 identified quiescent post-progenitor epithelial and mesenchymal cells in developing rat hair follicles, suggesting it may help track the differentiation of these cells.

The researchers reported that finasteride treatment in male rats may lead to changes in antioxidant enzyme activity in their offspring's epididymis, potentially affecting sperm maturation.

This review discusses the various roles of RANK signaling in bone remodeling, immune function, and epithelial differentiation, highlighting its potential involvement in cancer mechanisms; it reports no new clinical results.

In this study, deleting the gene Mettl3 in mouse epidermal progenitors resulted in impaired epithelial development and self-renewal, highlighting m⁶A's crucial role in regulating chromatin modifiers and maintaining normal epithelial tissue function.

This study demonstrated how cellular flows and tissue mechanics guide the topological transformations in avian skin, essential for feather follicle development from scales.

This study found that ARHGEF3 is crucial for hair follicle development in mice, as its absence leads to defects in placode compaction and impaired follicle downgrowth, highlighting its role in regulating cell shape rearrangements during embryogenesis.

This study introduces the multiple papillary centres model, offering a new explanation for hair twisting by combining known hair morphology features with differential growth rates caused by dermal papillae.

This article discusses the development and research applications of human hair follicle organ culture techniques, highlighting its potential to explore biological processes beyond dermatology.

This protocol describes a method for regenerating hair follicles using a bioengineering technique called the Organ Germ Method, but it reports no new clinical results.

This study found that retinoic acid induces epidermal transdifferentiation into mucosal epithelium in both chick and mammalian embryonic skin, involving specific gene expressions and pathways.

This study reviews prior research using transgenic K6/ODC mice and demonstrates that elevated polyamines in epithelial cells contribute significantly to skin tumor development and progression by stimulating proliferation, altering cell signaling and chromatin remodeling, and affecting immune functionality, amongst other mechanisms.

This study provided a dynamic 4D atlas showing the development process of mouse hair follicles through a telescope-like model, revealing new insights into the origin of hair follicle stem cells.

This special issue reviews recent progress in hair research discussed at the 2001 International Hair Workshop, reporting developments in androgen action, stem cell biology, and potential therapies for hair growth disorders without presenting new experimental results.
