In this study, researchers used a mouse model to identify an adipocyte-to-fibroblast conversion pathway that promotes mast-cell recruitment and dermal fibrosis in atopic dermatitis, suggesting a potential therapeutic approach to block this process and reduce inflammation and fibrosis.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This review discusses the roles of dermal white adipose tissue in skin functions and pathology, underscoring its antibacterial activity and potential anti-fibrotic role, but reports no new experimental results.

This review explores the roles of dermal sheath cells in wound healing, highlighting their multifunctional contributions to inflammation, proliferation, and extracellular matrix remodeling, and proposes new insights into tissue regeneration and repair, especially in differentiating between hairy and non-hairy skin sites.

This study found that in murine dermis, fibroblast state switching between proliferation and ECM deposition plays a crucial role in tissue architecture and wound healing.

This review highlights that injectable biostimulatory agents like poly-L-lactic acid, polycaprolactone, and calcium hydroxyapatite are effective in regenerative aesthetics by enhancing collagen production, stimulating adipogenesis, and improving dermal quality, although further research is needed to standardize protocols and confirm long-term safety and efficacy.

This study found that non-thermal plasma treatment increased epidermal thickness and dermal collagen density in mouse skin tissue without causing damage, potentially promoting growth factors and tissue remodeling.

In this study, a hydrogel loaded with SHP099 was shown to improve wound healing by targeting different cell types during various stages of the healing process.

This study found that the expression levels of Siah1 and Siah2 in mice skin vary dynamically during postnatal hair follicle development, suggesting their specific roles in modulating the HIF pathway.

Wound healing is a complex process involving different cells and stages, leading to scar tissue formation and strength increase over time.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This review explores the role of macrophage subsets in adult cutaneous wound healing and emphasizes their potential for therapeutic targeting, but reports no new experimental results.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This review discusses the potential of exosome-based therapies in dermatology, highlighting their ability to treat conditions like alopecia and accelerate wound healing, though further research is needed to understand long-term safety and develop standardized clinical protocols.

This review examines the use of platelet rich fibrin for treating post-acne scars and reports no new clinical results; it highlights that fibrin's matrix enables a prolonged release of growth factors.

This study found that CD26+ fibroblasts are crucial for effective extracellular matrix production and achieving rapid epidermal and dermal homeostasis in human tissue-engineered skin substitutes transplanted onto rodents.

This study found that inhibiting the interaction between HOTAIR and EZH2 can block pro-fibrotic gene expression in fibroblasts and interfere with tissue remodeling in systemic sclerosis patient skin.

In this pilot study, the researchers observed that transplanting anagen hair follicles into human scars can promote remodeling of fibrotic tissue and inhibit pro-fibrotic factors, offering potential new treatments for mature scars.

This chapter reviews the clinical evidence of adding platelet-rich plasma to lipofilling for tissue regeneration, with suggestions of benefits in skin rejuvenation and wound healing, but lacks well-designed trials.

This study found that the DexIEME hydrogel promotes complete skin regeneration and scar attenuation in murine and porcine models, suggesting potential for treating deep dermal injuries.

Radiofrequency devices effectively tighten skin without surgery.

This study suggests that the hairless gene encodes a nuclear factor important for hair follicle integrity, and its absence leads to hair follicle loss and defects in tissue development.

This study highlights restorative dermopigmentation as a growing field in aesthetic medicine, aiming to address skin concerns like alopecia and age-related pigment loss by improving aesthetic and structural dermal deficits.

In this study, epidermal stem cells were found to enhance blood vessel formation and support successful one-step transplantation of tissue-engineered skin in a rat model.

This study found that topical rebamipide, originally a gastric ulcer medication, can activate hair follicle stem cells and promote hair regeneration by modulating dermal adipocyte metabolism, with potential targeting of the prostaglandin E receptor EP4.

This study found that a mesenchymal stromal cell-derived regenerative extracellular matrix (rECM) significantly accelerated wound closure and improved healing in diabetic mice, also enhancing nerve and blood vessel formation compared to controls.

This study found that "micro skin tissue columns" improved wound healing by enhancing re-epithelialization, collagen deposition, dermal remodeling, and reducing inflammation without causing long-term donor site morbidity.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.
