Early-stage skin substitutes improve wound healing and skin structure.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

This article offers a viewpoint on hidradenitis suppurativa pathogenesis, suggesting that impaired Notch signalling from γ-secretase mutations may drive inflammation and link the condition to other Th17-driven diseases.

This review discusses the role of Edar signaling in hair follicle development and cycling, emphasizing its impact on cell fate, differentiation, and interactions with other pathways, but reports no new results.

In this study, researchers used transcriptomics and modeling to uncover previously unknown cell populations and marker genes in developing hair follicles, providing insights into early cell fate establishment and offering tools for further research on skin appendages.

This study found that manipulating Wnt/β-catenin signaling in embryonic mammary glands impacted their development, with high activity levels hindering branching and potentially redirecting cells toward hair follicle identity instead of mammary tissue.

In this source, recent single-cell RNA-sequencing advances reveal significant transcriptional heterogeneity among skin fibroblasts, and the discussion focuses on the distinct subtypes' roles in skin homeostasis, repair, and their evolution in fibrotic diseases like keloid scars and cancer.

Secreted inhibitors of Wnt and IGF signaling control hair and tooth development, creating species-specific patterns.

This study found that a bioprinted hydrogel scaffold with zinc and silicon ions significantly activated hair follicle stem cells and enhanced blood vessel formation, promoting hair growth in mouse wound models.

In this study, researchers found that extrafollicular progenitors marked by Hic1 are the main contributors to reparative fibroblasts in wound repair, with potential to modulate healing outcomes through genetic and pharmacological interventions.

This study found that ablation of Tet2/Tet3 genes in skin epithelial cells altered hair shape and length, leading to hair loss, by affecting chromatin accessibility and gene expression related to hair follicle regulation.

This review summarizes recent research on the therapeutic uses of adipose-derived stem cells for wound healing and treating skin diseases but does not provide new experimental results.

In this study, researchers used a mouse model to demonstrate that expression of MARCKSL1 in dendritic cells plays a crucial role in modulating fibrotic responses and scar formation during wound healing, suggesting that targeting this expression could offer new therapeutic strategies for scar prevention.

The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

This study found that CD34+ cells from adipose tissue may enhance hair morphogenesis and participate in blood vessel formation in reconstituted skin tissues of mice.
