This study identified the dermal sheath as a driver of hair follicle regression through muscle contraction, essential for reuniting niches and stem cells to regenerate tissue structure during homeostasis.

This study found that Polycomb Repressive Complex 1 is crucial for maintaining stem cell identity across different lineages, but its loss results in varied transcriptional outcomes depending on the tissue context.

This study found that ILK/ELMO2 complexes in epidermal keratinocytes are selectively activated by epidermal growth factor to induce cell migration, unlike with other growth factors.

This study found that weakened anchorage of hair shafts, associated with the abnormal expression of 14-3-3σ, may contribute to alopecia in Er/+ mice.

This study found that SYP123 and VAMP727 are involved in the secretion and transport of inner cell wall components, which is crucial for hardening the root hair shank in Arabidopsis.

This study observed that epidermal-specific deletion of aPKCλ in mice disrupts hair follicle stem cell quiescence, leading to altered hair follicle cycling and skin anomalies.

In this study, researchers found that Sox9 is critical for determining whether Nestin⁺ stem cells in adult mouse skin develop into melanocytes or glial cells, offering insights into possible paths for melanoma research.

This study suggests that varying intersheet interactions may explain the differences between the two polymorphic forms of macrofibril assembly in Merino wool and hair.

This study found that m6A-circHECA enhances the differentiation of stem cells into hair follicle lineages in cashmere goats by sequestering miR-449a-5p, boosting LEF1 gene expression, and activating the Wnt/β-catenin pathway.

Merkel cells likely attract sensory nerve fibers.

This review discusses the potential roles of calcium in the regulation of pluripotent and tissue-specific stem cells but reports no new experimental results, highlighting areas for future research.

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.

In this exploratory in vitro study, treatment with spermidine increased cell viability and altered gene expression in human epidermal keratinocytes, suggesting potential benefits to cellular health and function, though effects on mitochondrial markers were not significant.

Ceramide Synthase 4 is crucial for healthy skin barrier function.

This study describes how manipulating the actin cytoskeleton, particularly through the gelsolin family proteins, may enhance regenerative healing in mammals, suggesting potential therapeutic pathways for improved wound repair.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

Targeting S100 proteins may help treat hair loss.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.

This study established a new in vitro culture system that supports the growth and dynamic self-organization of hair follicle stem cells and their progeny, promoting a stable population equilibrium.

This study found that Polycomb repressive complex 1 is crucial for skin development and stem cell specification, influencing gene activity beyond its known repressor functions.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

Krox20 is important for cell differentiation in the brain and hair follicles.

This study suggests that Myc superfamily transcription factors may have distinct roles in different epithelial compartments of the human hair follicle, possibly influencing cell fate in the putative stem cell compartment.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

In this study, researchers identified that upon tissue injury in a mouse model, epidermal cells at the wound edge convert to an embryonic-like state with SOX11 and SOX4 playing a central role in modulating epidermal development and cell migration genes.

CD34 is a marker for isolating stem-like cells in mouse hair follicles.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.
