Skin cells can help create early hair-like structures in lab cultures.

This review explores the potential genetic and epigenetic influences on hair whorl patterns and suggests that pattern formation may involve basic physical-chemical laws, although it reports no new experimental findings.

This study describes two methods for isolating hair follicle stem cells from newborn Yangtze River Delta White Goats, highlighting differences in cell viability and marker protein expression between the methods.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study found that Wnt5a regulates hair follicle differentiation in mice by mediating epithelial-mesenchymal interactions and influencing dermal papilla cell activities.

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 cilostazol promoted hair growth in human dermal papilla cells and mouse models, suggesting its potential as a therapeutic target for alopecia treatment.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

This study found that two microRNAs, oar-miR-23b and oar-miR-133, inhibit the development of hair follicles in superfine wool sheep by targeting genes involved in key signaling pathways, suggesting their potential use as molecular markers for breeding fine wool sheep.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

In this study, the authors concluded that the TS-associated polyomavirus may disrupt Wnt/β-catenin signaling, likely contributing to abnormal hair follicle formation in trichodysplasia spinulosa.

In this study, CTCF was found to play essential roles in epidermal differentiation and skin barrier formation, simultaneously acting as a suppressor of epithelial inflammatory responses in mouse skin.

This study found that miR-486 and miR-451 levels were reduced in alopecia areata-affected skin, and delivering their mimics to mice mitigated symptoms by reducing inflammation and immune activity.

This study found that hyperproliferative stimuli dysregulated the balance of stem cell divisions in keratinocytes, suggesting potential treatment strategies for both benign and cancerous hyperproliferative diseases.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This research re-analyzed single-cell gene expression data from a mouse model, confirming that certain genes involved in the EDA-EDAR and WNT pathways are crucial for skin appendage development, suggesting that their restoration may mitigate the effects of hypohidrotic ectodermal dysplasia in children.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.
