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 reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

This study showed that ultrapulse carbon dioxide laser ablation can precisely remove rabbit skin without scarring, facilitating normal skin and hair restoration within one month.

This study found that using cultured mesenchymal stem cells from mouse whisker hair follicle outer root sheath in wound healing reduced inflammation, accelerated closure, and resulted in less hypertrophic scarring in mice.

This review examines the role of endothelial precursors and cellularized scaffolds in wound repair and revascularization for treating full thickness skin loss, but reports no new clinical results.

This study found that photoepilation in mice may disrupt normal dermal wound healing and increase the risk of hypertrophic scars or keloids.

This review examines the diversity and role of stem cells in the adult dermis, noting a lack of precise understanding about their hierarchy and relationship to dermal fibroblast subpopulations, and reports no new results.

This study found that intradermal bleomycin injections induced dermal fibrosis in C57BL/6 mice, evidenced by hair follicle obliteration and dermal thickening, though no significant trends in gene expression were observed, indicating the need for further research to understand the link between fibrosis and dyschromia.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

This review explores the evolution and development of skin-associated adipose tissue and proposes new nomenclature for the cells and adipose tissue underlying the reticular dermis, without reporting clinical results.

This practical guide introduces methods to study human dermal white adipose tissue but does not report new clinical results, emphasizing available techniques and staining protocols.

This study found that new methods for isolating human dermal papilla cells were more efficient than traditional methods, maintaining higher levels of specific markers and improving the cells' research potential.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This study developed a protocol for acellular dermal matrix manufacturing from pig skin, demonstrating effective removal of cellular components while preserving the collagen scaffold's structural organization through a series of physical and chemical treatments.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

A new method improves the isolation of hair follicle cells for better hair growth research.

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

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 advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

This study suggests that dermal adipocytes might play a key role in skin aging due to their transformation into fibrotic structures in chronically photo-damaged skin.

This study found that ECMs from papillary and dermal papilla fibroblasts support normal basement membrane formation, suggesting potential improvements for therapeutic biomaterials in skin engineering.

This study reports that in systemic sclerosis, CD34+ dermal fibroblasts transition to CD34−, podoplanin+, and CD90+ fibroblasts across the dermis, suggesting a role in unchecked fibrosis.

In this study, CD109 overexpression in transgenic mice led to reduced inflammation and improved collagen organization during wound healing without affecting wound closure.

This abstract provides no research results, focusing instead on navigation and subscription details for JAMA Dermatology content access.

This review examines advancements in hydrogel formulations aimed at preventing dermal fibrosis and promoting scarless wound healing, highlighting their role in regulating myofibroblast differentiation and controlling the wound microenvironment.

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.

Skin organoids can mimic human skin responses to injury and inflammation, making them useful for studying skin diseases and testing treatments.

This study describes a novel method using force-triggered density gradient sedimentation for efficiently isolating dermal papilla cells from neonatal mouse skin, showing promise for hair follicle regeneration research.
