This study found that interleukin-1α and interleukin-7 secreted by keratinocytes enhance the proliferation of γδT-cells and epidermal stem cells, revealing mechanisms of stem cell activation during wound healing in mice.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

This review discusses recent findings on fibrotic lipodystrophy, highlighting the critical roles of lipid-filled cells in tissue function and their loss during fibrogenesis, with implications for fibrosis in tissues like skin, lung, and liver.

This review discusses the roles of extracellular vesicles in skin health and disease and reports no clinical results; the authors highlight potential therapeutic uses and call for more research.

This review article discusses microneedling as a non-surgical treatment option in dermatology, highlighting its benefits for scar improvement through collagen induction and reporting its popularity among practitioners due to its cost-effectiveness and simplicity.

This review discusses the cosmetic applications and healing phases of microneedling and reports no new clinical findings; the authors highlight its use for skin and hair treatments without epidermal damage.

This study found that gelatin microspheres loaded with platelet-rich plasma enhanced wound healing in rats by improving inflammatory and angiogenic responses compared to untreated wounds or PRP alone.

This article reviews the diverse regulatory roles of alpha-melanocyte-stimulating hormone in skin biology, highlighting its potential involvement in maintaining tissue homeostasis and protecting against inflammation-induced DNA damage but reports no new clinical findings.

In this case report, an 8-year-old girl with burn-induced cicatricial alopecia showed improved graft survival after hair transplantation due to preparatory microfat grafting, which enhanced tissue conditions and possibly increased follicular unit survival rates to about 80%, higher than typically expected.

This study found that targeting IL-17 signaling in aged skin reduces inflammation and delays age-related traits, suggesting a potential strategy to prevent age-associated skin ailments.

This study found that dexamethasone treatment inhibited the inflammatory response and the induction of ornithine decarboxylase activity in mouse skin after TPA application, although the effect on ODC was weaker during the hyperplastic stage.

This study explored a novel finasteride-loaded nanoparticle gel for treating alopecia areata, finding that it significantly increased hair follicle number and size without causing skin irritation, presenting an effective alternative to traditional minoxidil treatments.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

This study found that PDGF-BB affects human melanocytes differently depending on their differentiation stage, stimulating melanoblast proliferation but inhibiting melanocyte proliferation while promoting their differentiation.

This narrative review concluded that facial aging involves complex anatomical changes that require multimodal rejuvenation approaches, integrating fillers, collagen stimulators, botulinum toxin, and energy-based devices for effective results, while emphasizing the need for scientific evidence and patient safety in aesthetic treatments.

In a mouse model of androgenetic alopecia, this study developed a treatment combining a copper-curcumin nanoparticle oleogel with traditional Gua Sha therapy, which augmented hair regeneration more effectively than minoxidil by improving the follicular microenvironment and regulation of inflammatory responses.

This study found that fibromodulin significantly reduces scar formation and boosts scar strength in rodent and porcine models, suggesting potential for FMOD-based therapies in cutaneous wound repair.

This study applied a novel method to the Italian economy and found that declining labor productivity from 1981-2004 was mostly due to a fall in total factor productivity growth.

This review discusses the advancements and challenges in skin bioprinting techniques and applications, including hair follicles and pigmentation, while addressing the need for improvements in vascularization, safety, and clinical translation, according to the authors.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.

This study found that extracts from the fungus YL161, Agaricus blazei, and the bark of Camptotheca cuminata promoted dermal papilla cell growth more effectively than pentadecanoic acid, suggesting potential for stimulating hair growth.

Different substances affect hair and skin cell growth in various ways.

Different substances affect hair and skin cell growth in various ways, with some promoting and others inhibiting cell proliferation.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study identified three genes with significantly higher expression in androgen-sensitive beard dermal papilla cells compared to androgen-insensitive scalp cells, suggesting potential novel signaling pathways in hair follicles.

This review explores the role of hair follicle dermal stem cells in skin regeneration and restorative therapies, but it reports no new experimental results.

Skin cells can help create early hair-like structures in lab cultures.

This study suggests that androgens enhance growth factor production in dermal fibroblasts, which in turn may alter keratinocyte differentiation and contribute to acne lesion formation.

This review discusses using cultured dermal papilla cells to investigate hair follicle biology, emphasizing their potential to inform treatments, but reports no new clinical results.

In this study, researchers developed a new 3D skin equivalent assay using mouse epidermal and dermal cells that successfully regenerated organized hair follicles, outperforming a 2D model in hair follicle orientation and quantity, and enhanced hair growth when Wnt3a was added.
