This study found that transplanted cultured epithelium from adult rat sole keratinocytes can respond to growth signals from dermal papillae and form follicular structures, especially with dermis support.

This study demonstrated that clonal dermal papilla and dermal sheath cell lines from hair follicles can differentiate into lipid and bone cells, suggesting their potential as a stem cell source for tissue engineering.

This study found that topical patches containing allicin from garlic extract may be a promising and cost-effective option for treating alopecia areata, offering better aesthetic acceptance than mashed garlic.

In this study, the researchers reported that using a biodegradable ECM scaffold for large-area wound regeneration accelerated wound coverage and improved hair follicle neogenesis by activating the adaptive immune system.

This study introduced a pH-responsive polymeric wound dressing that enhances healing in chronic wounds by changing shape and drug delivery based on wound pH, achieving a 94.88% healing rate in diabetic mice by day 14.

This study found that Dermal Fibroblast Progenitors have repressed chromatin profiles which hinder their ability to reform skin in allograft assays despite their differentiation potential.

This study describes a preliminary examination showing that an intraepidermal injection of autologous epidermal cell suspension contains a significant number of viable cells after 7 days of culture, suggesting potential use in treating skin disorders like alopecia and as an anti-aging therapy.

This study found that mesenchymal stem cells, especially when injected intradermally, significantly accelerated wound healing in rats compared to chitosan treatment.

This study reports the creation of a human dermal mesenchymal-like stem cell line from an androgenetic alopecia patient, which may serve as an in vitro model to explore alopecia mechanisms.

This review highlights that skin organoids, advanced three-dimensional models mimicking human skin, are emerging as effective alternatives to traditional culture models and human skin, overcoming limitations of two-dimensional systems and ethical concerns, and are being increasingly used in areas like developmental biology and disease modeling.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This review explores the potential of alginate as a promising alternative to donor tissue for corneal transplantation due to its adaptability, transparency, and low immunogenicity, and discusses how chemical modifications can enhance its properties for use in corneal tissue engineering.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

This study describes a protocol for generating hair follicle germ-like organoids from human skin cells, which may aid in alopecia drug discovery and understanding hair follicle regeneration.

One type of progenitor cell can maintain normal skin in mice.

This article describes the Dermatologic Surgery journal's coverage of a wide range of skin surgery topics but reports no new research findings.

In this study, microporous electrospun scaffolds pre-seeded with dermal fibroblasts accelerated wound healing and improved dermal matrix structure and hair follicle regeneration compared to acellular scaffolds in a rat model.

This study explains how the development of keratin-associated proteins in embryonic epidermis is crucial for forming protective barriers in vertebrates, enabling them to adapt to terrestrial environments.

This study found that microencapsulated dermal papilla cells implanted into mice ears led to the successful regeneration of hair follicles, with APA microencapsulations of 400µm diameter allowing effective nutrient exchange.

This study found that a collagen patch made with fibroblast-derived extracellular matrix (fdECM) extracted from human lung fibroblasts enhanced wound healing by promoting wound contraction, angiogenesis, and skin remodeling in full-thickness skin wound models, including those with diabetic ulcers.

In this study, poly (ɛ-caprolactone)–chitosan–poly (vinyl alcohol) nanofibrous scaffolds used on canine skin wound models were found to significantly accelerate healing rates of excision and burn wounds, without inducing immunogenic reactions.

This study demonstrates that trichogenic dermal papilla cells are crucial for hair regeneration in engineered skin substitutes, with adult murine cells showing higher activity than adult human cells.

This study found that dermal papilla cells and dermal sheath fibroblasts can induce hair follicle formation when combined with hair follicle epithelial cells, both in vitro and in vivo in nude mice.

This study observed that patients with different types of alopecia exhibited variable epidermal thickness and consistent dermal changes, including hair follicle destruction and lymphohistiocytic infiltrates, which may suggest inflammation.

This study developed protocols to create skin organoids with hair follicles and other appendages from human induced pluripotent stem cells, representing a significant step towards understanding hair follicle development and potential applications in modeling skin diseases and reconstructive surgeries.

This article discusses the structure and protective function of pangolin scales, emphasizing their composition of α-keratins and β-keratins, and highlights evolutionary keratin diversification in tetrapods; it reports no new empirical findings.

This review outlines the role of dermal fibroblasts in wound healing and highlights their potential in developing new cellular therapies, but reports no new clinical results.

The researchers reported that using exosomes from hair follicle stem cells with acellular nerve allografts helped bridge facial nerve defects in rats and may match the effectiveness of autograft therapy.
