In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This review discusses the dynamic changes in chromatin organization and nuclear morphology during cellular processes like differentiation and disease, highlighting recent advances in understanding these epigenetic mechanisms without presenting new experimental findings.

This study found that the AtSfh1 protein in Arabidopsis is essential for phosphatidylinositol-4,5-bisphosphate signaling crucial to polarized root hair growth, utilizing both phosphatidylinositol and phosphatidylcholine-binding activities.

In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

In this study, researchers reported that hair follicle stem cells maintain quiescence through a PIEZO1-dependent mechanism that senses mechanical forces and translates them into localized calcium influx, involving a transcriptional network that regulates cell adhesion and cytoskeleton-related genes.

This review describes the hair follicle's structure, particularly its role as a stem cell niche, and discusses its potential application in skin tissue engineering, but does not present new research findings.

This study found that a peripilar white gray halo around hair emergence is a highly specific and sensitive dermatoscopic feature for diagnosing central centrifugal cicatricial alopecia in African American patients with mild central thinning.

This study found that desmosomal adhesion plays a crucial role in epithelial morphogenesis and cell positioning, equivalent in importance to that of adherens junctions.

This study identified a population of GFP-expressing nestin-positive cells in transgenic mice hair follicles that varied in location during different hair cycle phases, suggesting a shared relationship with neural stem cells.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.

In this study, hair follicle stem cells from ND-GFP transgenic mice were observed to be pluripotent, effectively repairing peripheral nerve and spinal cord injuries in mouse models.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This study shows that ZIP7 is a functional zinc transporter in mammalian cells, facilitating the movement of zinc from the Golgi apparatus to the cytoplasm.

This study used Cisd2 knockout mice models and found that these mice display premature aging characteristics and an increase in dysfunctional neutrophils, suggesting Cisd2's role in calcium homeostasis and neutrophil function via interactions with Calnexin and SERCA.

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 research discusses the time-of-day-dependent role of protein-complex assembly in the differentiation of human epidermal stem cells and highlights the context-dependent functioning of human protein complexes.

In this study, researchers used quantitative fate mapping to investigate how the infundibulum, part of the epidermis, is maintained during adulthood, finding that progenitors maintain this tissue through stochastic cell fate choices, with cells at the bottom providing transient support during hair growth phases.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

In this study, researchers found two distinct stem cell reservoirs in human hair follicles that require mesenchymal cells for stem cell proliferation.

This study reports that in mice, retinoic acid mediates communication between hair follicle and melanocyte stem cells by influencing differentiation in their shared niche during hair regeneration.

In this study, researchers observed that quiescent mouse embryonic fibroblasts showed reduced glycolysis but increased TCA cycle flux and mitochondrial respiration, with these changes linked to metabolic reprogramming involving yes-associated protein inhibition and malate cycle modulation, which supports extracellular matrix protein synthesis.

This study found that BMP2 increased PTEN expression and induced autophagy, promoting hair follicle stem cell differentiation in both in vitro models and a mouse wound model.

This study found that Wnt signaling regulates the symmetric division of adult neural stem cells, increasing their numbers during subependymal regeneration, stroke response, and colony formation.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This study found that enteroendocrine cells play a key role in coordinating stem cell migration towards wounds in the Drosophila intestinal epithelium, aiding tissue repair through non-canonical Wnt signaling.
