This study found that a positive feedback loop involving RHD2, reactive oxygen species, and calcium ions helps maintain root hair growth sites and influences cell shape in Arabidopsis thaliana.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

In this study, researchers found that a positive feedback loop involving Ca 2+ and RHD2 NADPH oxidase-derived ROS helps maintain growth sites, crucial for root hair development and cell shape in Arabidopsis thaliana.

In this review, the researchers highlight the role of fibroblasts in regulating the extracellular matrix and immune responses, emphasizing the impact on macrophages and potential therapeutic insights for fibrotic diseases and cancer.

The researchers reported that yak hair fibers undergo macromolecular conformational changes and partial slippage of macromolecules during stretching, confirming this as the main stretching mechanism when the stretching ratio is large.

This review discusses the roles of metabolism, reactive oxygen species, intracellular pH, and cell morphology in influencing cell fate decisions during stem cell differentiation but reports no new experimental results.

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 study found that DermaCult™ Keratinocyte Expansion Medium allows for significantly extended growth of human epidermal keratinocytes while maintaining their differentiation potential.

Cell movements and forces shape feather growth in chicken skin.

This study found that dermal papilla cells from human hair follicles form multi-layered aggregates when cultured in vitro, contrasting with the monolayer growth of dermal fibroblasts.

This article reviews techniques for achieving natural-appearing hair restoration results in women and reports no new research findings.

This study found that generating pluripotent stem cell-derived skin organoids in a 3D bioprinted hydrogel device improved keratinocyte differentiation and hair follicle formation while reducing necrosis.

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.

Vascular patterns in dermoscopy help tell apart malignant and benign skin tumors.

This study reported the case of a 30-year-old man with a bluish-grey scalp nodule that developed over a previously stable hairless plaque, revealing histopathological features consistent with epithelioid cell nests and spindle-shaped dermal melanocytes embedded in collagen.

This article reports an unprecedented case of trichofolliculoma in the gluteal area, previously unreported in English literature.

Curly and straight hair differ in how their internal fibers are arranged.

This study found that Y27632 treatment facilitated the formation of core-shell-shaped hair follicle organoids, resulting in nearly 100% efficient hair shaft sprouting in vitro.

This study found that disrupting Lm332 expression in mice changes keratinocyte genetic expression, alters cell shape, and disrupts epidermal homeostasis, despite some compensatory anchorage by hair follicle basal cells.

This review discusses the role of intermediate filaments in cell signaling and differentiation, emphasizing their impact on stem cell function, development, and disease, but reports no new clinical results.

In this study, the type II subunit of porcine hair keratin was found to significantly inhibit the differentiation of PC12 neural cells compared to the crude extract and type I subunit, although cell proliferation was unaffected.

This study found that microencapsulated dermal papilla cells in hyaluronic acid/collagen hydrogel retained their ability to initiate hair follicle regeneration, suggesting potential for alopecia treatment.

This study observed that after hair cell loss in the mouse cochlea, supporting cells were replaced by migrating non-specialised cells, with genetic background affecting the rate of tissue re-organization.

This study found that the development and differentiation of Merkel cells in C57BL mouse embryos' dorsolateral skin are linked to tylotrich follicle formation rather than to neural influences.

This study found that in naturally curved human scalp hairs, distinct arrangements of cell types on either side of the hair fiber contribute to its curvature.

This study introduced a theoretical model suggesting that the morphological transition from bud to cap in tooth germ development is driven by mechanical interactions among cells.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.
