In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

This study found that the repressive histone mark H2AK119ub links inhibitory FGF signals with the quiescent state in hair follicle stem cells, revealing a signaling-epigenetic axis crucial for maintaining stem cell quiescence and tissue homeostasis.

This review discusses the roles of the transcription factor SOX9 in organ development and maintenance, providing insights into its regulation and diverse functions, but reports no new experimental results.

This review discusses the paracrine function of mesenchymal stem cells in tissue regeneration and repair, focusing on secreted bioactive substances and their role under different microenvironments; it reports no new clinical results.

This study found that overexpression of an enzyme in transgenic mice led to distorted polyamine levels, resulting in permanent hair loss and female infertility.

This study found that PBX1 enhances the proliferation and reprogramming of hair follicle mesenchymal stem cells by activating the AKT/GSK3β signaling pathway, promoting NANOG expression, and inhibiting apoptosis.

S100A8 and S100A9 proteins help form hair shafts during growth.

This study found that deleting the Mad2l1 gene in mice leads to rapid onset of acute lymphoblastic leukemia and liver cancer due to induced chromosomal instability.

In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.

This study found that hair germ cells, derived from bulge stem cells, respond faster to dermal papilla signals and have limited proliferation compared to bulge cells during hair regeneration.

This review discusses the biochemical and biological functions of histone demethylases and their potential involvement in human diseases, including cancer, but reports no new findings.

This study demonstrates that YAP and TAZ are essential for initiating basal and squamous cell carcinomas in mice, and suggests targeting these pathways could be beneficial for treating skin cancers.

This review discusses the role of astrotactins in development and their genetic mutations' links to a variety of human diseases, but reports no new clinical results.

In this study, researchers explored the heterogeneity of pigment cells in the human scalp anagen hair follicle bulb and discovered unexpected subpopulations of melanocytes, including immature SOX10-negative cells, highlighting potential non-melanogenic roles or transitional migratory functions that require further investigation.

Hox genes control hair follicle stem cell regeneration in different body regions.

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.

This study found that astrotactin-2 undergoes unique intramembrane proteolysis during maturation, revealing specific transmembrane topologies and substrate sequence requirements for cleavage.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

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 provides evidence that ILC1-like cells can induce alopecia areata in previously healthy human hair follicles, challenging the view that it is solely an autoantigen-dependent autoimmune disease.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

In this study on Arabidopsis, the researchers identified CIPK13 and CIPK18 as crucial genes for root hair growth, finding that deficiencies in these genes resulted in shorter root hairs and reduced growth rates due to altered calcium oscillations.

This article discusses the interactions between keratinocytes and melanocytes in maintaining epidermal and hair follicle homeostasis, without reporting new experimental results.

In this study, human umbilical cord mesenchymal stem cell-derived exosomes were found to promote the growth of human hair dermal papilla cells, partly by enhancing AKT-dependent signaling pathways, suggesting a potential role in treating hair loss.

This study found that cultured hair follicle dermal cells support maintenance and potentially aid in the clinical application of pluripotent and haematopoietic stem cells.

In this study, researchers analyzed the skin proteome of Alpine Merino sheep to identify proteins and pathways related to wool fiber diameter, finding that cyclic adenosine monophosphate and certain signaling pathways may play a role in this trait.

In this review, it is discussed how mesenchymal stem cell aggregation plays a crucial role in organ development and has potential applications in organ regeneration through tissue engineering.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

In mouse models, this study showed that transplanted dermal papilla and dermal sheath cells can integrate into hair follicles, promoting hair growth and extended anagen phases, with their effectiveness influenced by factors such as immune response and cell passage number.

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.
