This study found that, in mice, different precursor populations give rise to Merkel cells in hairy versus glabrous skin, but their formation is controlled by a common genetic program involving FGFR2 signaling.

This study found that transplanting genetically modified dermal fibroblasts into full-thickness skin defects in rats led to the formation of hair follicles with mature pilosebaceous systems by 16 weeks.

This review discusses the roles of fibroblast growth factors in tissue regeneration and repair across various organisms and tissues, but reports no new experimental findings, underscoring the need for further research.

This study identified a novel LZTR1 mutation associated with hybrid schwannoma and neurofibroma in a patient with schwannomatosis, but not all cases of hybrid tumors are linked to this condition.

In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

This research found that deleting the SLC3A2 gene in hair follicle stem cells disrupts their maintenance and proper differentiation, leading to hair follicle growth defects and altered skin regeneration through a YAP/Taz-dependent pathway.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

This review discusses the complex role of the EDA pathway in vertebrate skeletal development, emphasizing its interaction with other morphogenic pathways to influence skeletal diversity, but reports no new experimental results.

This research identified a genetic mutation in Brachypodium distachyon that initially allows root hair initiation but fails to elongate them, while also affecting root growth and nitrate sensitivity; the mutation is linked to a previously uncharacterized cyclin-dependent kinase-like gene.

In this study, Hedgehog signaling in dermal papilla fibroblasts was found to accelerate hair growth and induce follicle multiplication in mice via the SCUBE3/TGF-β pathway, with some effects observed in human scalp hair follicles.

This study highlights the ZmNF-YC1-ZmAPRG pathway as a potential mechanism to improve maize tolerance to phosphorus deficiency, emphasizing its role in modulating lipid and photosynthetic activity, although direct impacts on root adaptations remain unclear (Bai et al., 2024).

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 study found that a 22-bp InDel polymorphism in the FGF7 gene was significantly associated with growth traits in goats, with genotypes ID and/or II linked to better growth compared to genotype DD, indicating its potential as a molecular marker in breeding programs.

This study found that mutant Cx43 impairs fibroblast function during wound healing and reduces hair follicle cell proliferation, likely contributing to hair growth defects in ODDD patients.

In this study, researchers found that FGF9 plays a significant role in sheep wool growth by accelerating the proliferation and cell cycle of dermal papilla cells, potentially through regulation of the Wnt/β-catenin signaling pathway.

This study highlights that human hair follicle dermal papilla cells and glypicans play crucial roles in regulating hair follicle stem cell differentiation.

Ovol2 is essential for normal skin and hair regeneration.

This study found that mice lacking the vitamin D receptor showed disrupted hair follicle cycling and balance between cell proliferation and differentiation, highlighting VDR's role in hair cycling regulation.

This study observed that infants exposed to diazoxide in utero exhibited abnormal hair growth and, in some cases, impaired glucose tolerance, particularly those born to diabetic mothers.

This study found a significant association between reduced FGF13 levels and X-linked congenital generalized hypertrichosis, suggesting FGF13's potential role in hair follicle growth and the hair cycle.

Fucoidan may help regrow hair and reduce inflammation in hair loss.

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 in Arabidopsis thaliana found that exposure to volatile compounds from Penicillium aurantiogriseum promotes root hair growth through signaling involving RALF22, ethylene, auxin, and photosynthesis, and that RALF22 plays a crucial role in the plants' response to these compounds.

This study reports that ZD1839 (Iressa), an anticancer drug, was associated with acneiform eruptions and hair growth abnormalities due to its inhibition of epidermal growth factor receptor signaling in the skin.

This review highlights the critical role of TGF-β and FGF signaling pathways in the development and regeneration of skin layers, particularly the dermis, and discusses their significance in advancing future clinical applications in dermatology.

This study found that deleting podoplanin in mouse keratinocytes promoted hair follicle growth during regeneration, suggesting it may regulate hair cycling pathways that could aid in treating hair loss conditions.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.
