In this study, researchers developed a multilayered gel bead culture model using a microgel-spotting device, successfully mimicking the early development of skin appendages and supporting in vitro hair follicle regeneration with structures resembling native hair follicles.

This study shows that microdiffraction experiments reveal structural layers in keratinous tissues, each with different keratin types, potentially explaining their dual role as mechanical support and chemical barriers.

In this animal study, ultrasound combined with a new microbubble formulation of minoxidil increased hair growth rates and improved follicle characteristics more effectively than minoxidil alone.

This paper reviews the complex histology of skin layers and underscores its importance for accurate and reproducible diagnosis in cutaneous pathology, but reports no new research findings.

This report describes a successful case where repeated autologous lipostructure followed by hair transplantation improved scarring alopecia in a patient with morphea en coup de sabre, suggesting potential benefits from this combined approach.

In this study, researchers developed a method using stencils to create controlled stiffness gradients in alginate hydrogels, revealing that stiffer regions within the gels promote deeper invasion by breast cancer cells, facilitating the study of mechanosensitive cellular behaviors.

Early-stage skin substitutes improve wound healing and skin structure.

This study describes a double embedding technique for preparing tangential sections of hair and wool fibers, recommending specific staining methods for quantitative analysis and demonstrating wool fiber cortical fractions.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

In this study, researchers developed a composite electrospun dressing with fiber gradient changes that mimics skin's natural structure, demonstrating enhanced wound healing, collagen deposition, and reduced fibrosis and scarring in both in vitro and in vivo experiments.

Three new techniques simplify and improve the preparation of tissue samples for skin cancer surgery.

This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.

This clinical study compared single-layer and multiple-layer wound closure after tympanoplasty, finding that single-layer closure was as effective but took less time and reduced surgery costs for patients with chronic suppurative otitis media.

This study developed a prototype pneumatic dual-cell implanter that successfully stacked and implanted cells in tests, reducing hand burden for operators, which may improve alopecia treatments compared to traditional hair transplantation.

This study observed that densely packed follicular unit grafts using the lateral slit technique have high growth rates, even at 72 grafts/cm², contradicting previous findings with older methods.

This article describes a surgical technique combining CO2 SilkTouch Laser and Calvitron Hair Transplant System that offers a natural-looking hairline with moderate session length and minimal bleeding, but reports no new clinical outcomes.

This article describes a hair transplantation technique that provides excellent results, reduces procedure time, and minimizes damage to follicular units compared to traditional methods.

This study compared single and double-layer wound closure in hair restoration surgery and found no significant difference in scar size or quality. Single-layer closure was faster, less costly, and had better scar mobility, according to the researchers' report.

This study developed a multifunctional core-shell fiber dressing that preserves platelet-rich plasma for 180 days, facilitating sustained growth factor release and improved wound healing.

Combining low-level laser therapy with topical corticosteroids effectively improved Lichen Planopilaris symptoms.

This review summarizes the research on bioactive materials that modulate the skin microenvironment to promote wound healing and highlights the essential role of the fascial layer, without presenting new experimental results.

In this narrative review, the authors discuss regenerative substances like platelet-rich fibrin and mesenchymal stem cells in biological aesthetics, noting that while these methods show promise for regeneration, their safety, effectiveness, and durability remain uncertain due to limited and heterogeneous evidence.

Cell movements and forces shape feather growth in chicken skin.

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.

A botanical lotion can increase scalp collagen and extend hair growth phase, potentially improving hair thinning issues.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This article describes an improved trichophytic closure technique for hair restoration surgery, achieving nearly invisible donor scars in over 95% of patients, but emphasizes tailoring the method to individual patient characteristics.

This study found that a novel hybrid bilayer scaffold system enhanced wound healing in an in-vivo model by promoting cell viability, migration, and preventing infection, showing potential as an advanced dressing for cutaneous wounds.
