This study found that mutant mice with the we/we wal/wal genotype exhibit significant defects in hair shaft structure and epidermis stratification, correlating with postnatal alopecia symptoms.

This study found that apoptosis, along with proliferation, plays a crucial role in shaping and extending human hair follicles by coordinating the formation and differentiation of the hair canal.

In this study, researchers identified the lncRNA MSTRG.14227.1 in cashmere goats and found it inhibits the morphogenesis of secondary hair follicles by interacting with the chi-miR-433/ADAMTS3 signaling axis, affecting cashmere yield and quality.

This study found that K79+ keratinocytes migrate outward to help form the hair follicle lumen both during development and adult regeneration, revealing a novel mechanism of hair follicle formation in mice.

This study explored the role of the histone modification H3K4me3 in cashmere goat dermal papilla cells, finding that increased levels enhanced cell proliferation and activated Wnt signaling genes, suggesting H3K4me3's involvement in hair follicle development through regulation of the gene RSPO3.

This study identified the NAC transcription factor RD26 as a critical regulator of drought-induced root hair growth restriction in Arabidopsis thaliana, with a similar mechanism observed in tomatoes, indicating evolutionary conservation.

This study found that combining human dermal papilla fibroblasts with hair matrix cells formed organoids capable of limited hair follicle development in ex vivo skin, but not fully formed hair follicles.

This study demonstrates that trichogenic dermal papilla cells are crucial for hair regeneration in engineered skin substitutes, with adult murine cells showing higher activity than adult human cells.

In this study, epithelial cell-derived exosomes promoted fibroblast migration and inhibited their proliferation, suggesting a role in dermal condensate formation and hair follicle morphogenesis in cashmere goats.

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.

In this mouse model study, researchers found that deleting the ASH2L gene in epidermal progenitor cells led to thinner epidermal layers, delayed hair follicle development, and reduced epidermal stem cell pools, with alterations in genes related to hair follicle development and the Notch signaling pathway.

This study found that DNA methylation regulates hair follicle differentiation in cashmere goats by suppressing gene expression during induction and enhancing it during differentiation, with potential involvement of specific lncRNAs.

This study found that the NuMA protein's microtubule-binding domain is essential for proper spindle orientation and differentiation in keratinocytes, affecting skin and hair development in mice.

Keratin 79 cells help form and regenerate hair canals.

EGF and FGF signaling stops hair follicle development in mice.

Retinoic acid receptors are important for hair follicle development.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This review summarizes current research on molecular pathways, such as Wnt and Notch, that regulate feather follicle development in yellow-feathered broilers, highlighting their potential impact on poultry carcass quality and suggesting areas for future study.

This article reviews the role of microRNAs in skin-related conditions like psoriasis and wound healing and highlights their potential as therapeutic targets and diagnostic biomarkers, without reporting new experimental results.

In this study on Drosophila wings, researchers identified 435 genes with significant expression changes during wing hair morphogenesis, and found new phenotypes for 9 genes through functional validation.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This study suggests that the COX-2 enzyme plays a role in hair follicle biology, as transgenic overexpression in mice induced hair follicle cycling disturbances and alopecia, which was mitigated by COX-2 inhibition.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that BAF200, a subunit of the PBAF chromatin remodeling complex, is crucial for heart development and coronary artery formation in mice, as its absence led to embryonic lethality with severe cardiac defects.

This review discusses key signaling pathways involved in tooth formation, highlighting their role in understanding tooth regeneration and potential therapies for dental abnormalities.

This study identified that the Wave complex proteins ABI1 and Wave2 play a crucial role in regulating epidermal shape and growth during skin development, notably influencing SOX9 expression and Wnt signaling pathways.

This study found that the p63 transcription factor is expressed during rat epidermal development and may serve as a specific marker for keratinocyte progenitor cells.

Retinoic acid causes gland formation instead of hair in mouse skin by altering epidermal and dermal interactions.
