This study identified gene expression differences between dermal papilla cells from primary and secondary hair follicles in Cashmere goats, highlighting their roles in hair follicle morphogenesis.

This study identified specific reflectance confocal microscopy features that help differentiate scarring from non-scarring alopecia, providing a non-invasive diagnostic tool.

This study found that intradermal administration of adipose-derived stem cell–conditioned medium significantly increased hair density and dermal thickness, suggesting potential regenerative effects on both hair follicles and the interfollicular scalp in patients with alopecia.

This research discusses the diverse populations and specialized roles of dermal fibroblasts in human skin, highlighting their distinct interactions and contributions to skin structure, without presenting new clinical findings.

This study reports that corneal transient amplifying cells can be reprogrammed into epidermal cells capable of forming hair follicles in response to embryonic dermis signals.

This study found that epidermal melanocytes can regenerate hair follicles, whereas non-cutaneous or dermal melanocytes cannot, suggesting two distinct melanocyte lineages with potential implications for melanocyte-related diseases.

This review discusses the role of Sox2 in skin development, hair follicle regeneration, cancer, and wound healing, and reports no new experimental results.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

Different types of stem cells and their environments are key to skin repair and maintenance.

This study found that IMT-P8, a novel cell-penetrating peptide, effectively facilitated the dermal delivery of proteins and peptides in mouse skin and cell lines, suggesting potential for topical applications in cosmetics and skin diseases.

This study suggests that interfollicular epidermal keratinocytes with stem-like features may serve as an alternative to follicular keratinocytes for hair regeneration by supporting hair follicle morphogenesis in vivo.

This study demonstrated that an engineered human skin equivalent can generate follicle-like structures resembling fetal skin, highlighting the role of the dermal compartment in directing epithelial cell fate in vitro.

This review outlines the processes and potential of stem cells in regenerating skin, hair, and other tissues but presents no new experimental findings.

This summary explains the different types of wrinkles, their causes, and their distinct microanatomical characteristics, noting that each type may respond differently to treatments.

This review discusses the use of dermal regeneration templates for treating burn injuries and other wounds, highlighting their effectiveness in reducing scars and aiding in regenerative processes, but reports no new clinical results.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This study found that non-ablative fractional erbium glass laser treatment affected gene regulation in human skin models by downregulating MMP and interleukin expression, suggesting potential roles in dermal remodeling and anti-inflammatory effects.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

This study observed that both Factor XIIIa+ dermal dendrocytes and microvasculature size decreased with scalp aging and that alopecia changes resembled stress-induced premature senescence.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This study demonstrated that prevascularized human skin constructs containing engineered hair follicles can successfully induce human hair growth when grafted onto mice by promoting blood supply to the grafted skin.

This review discusses the various skin lesions associated with COVID-19, which vary in type and severity, and reports that these lesions can appear before other symptoms and typically resolve spontaneously.

This study found that water extract of olive leaf may enhance markers linked to epidermal and dermal stem cell activity and potentially improve skin aging, especially in individuals who do not exercise regularly.

This review discusses the relationship between zinc deficiency and skin disorders, emphasizing zinc transporters' roles, but it reports no new clinical results; the authors highlight potential benefits of regulating zinc levels via transporters.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study found that mesenchymal cell processes from the dermal papilla contact epithelial hair matrix cells through gaps in the basal lamina during hair matrix cell differentiation in mouse vibrissa follicles.

In this study, researchers found that androgen receptor activation in dermal papilla cells mainly affected the focal adhesion pathway and downregulated caveolin-1 gene expression, which could help identify new therapeutic targets for testosterone-related diseases.

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.

This study observed that both TCA (35%) and GA (70%) chemical peels improved skin morphology and stimulated bulge stem cells in albino rats, with no significant difference between the two agents.

In this study, topical piperonylic acid was found to improve wound healing in mice by activating EGFR and modulating gene expression related to the healing process.
