This study concluded that the follicular route is a significant pathway for delivering gentamicin through the skin, as demonstrated by higher drug permeation in non-plugged pig's ear skin compared to plugged skin.

This study found that implanting microencapsulated dermal papilla cells in rat ears led to hair follicle regeneration, suggesting a potential alternative to fresh isolated dermal papillae for inducing hair growth.

In this review, the authors discuss how understanding and co-regulating multiple signaling pathways could lead to effective regeneration of functional hair cells, highlighting current achievements and future approaches such as small molecule drugs and gene therapy for treating sensorineural hearing loss.

This study found that radiofrequency radiation from mobile phone use may increase DNA damage in hair follicle cells of the ear canal, with greater exposure duration linked to higher damage levels.

This study details the histological structure of the white domesticated pig's ear skin and discusses its relevance as a model for human dermatological research.

In this study, researchers developed a new murine model for transplanting vibrissae that mimics human hair transplantation, achieving successful hair growth in immune-deficient nude mice.

This study found that Black patients with discoid lupus erythematosus had significantly worse CLASI damage scores and higher odds for dyspigmentation, scalp involvement, and scarring alopecia compared to non-Black patients.

In this study, Malassezia pachydermatis infection was more common in German shepherd dogs and occurred more frequently in January and February compared to other months in Diyala Governorate.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

This study found that specialized nipple epidermis in mice is maintained by the repression of TGFβ signaling through estrogen, which highlights the role of hormonal regulation in epidermal maintenance.

This study found that transgenic expression of COX-2 in mouse basal keratinocytes causes epidermal hyperplasia and certain dysplastic features at specific body sites.

This study found that the contribution of the hair follicle pathway to skin permeation of chemicals can be predicted using lipophilicity, with hydrophilic chemicals showing greater permeation reduction from hair follicle plugging than lipophilic ones.

This study found that large excisional wounds in rats across seven strains do not regenerate new hair follicles, unlike in mice, possibly due to differences in epidermal competence and transcriptional profiles.

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 in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

This study found that proton minibeam radiotherapy demonstrated a potential tissue-sparing effect in epidermis models by spatially confining DNA damage, suggesting reduced side effects in radiotherapy.

This review examines skin diseases affecting the pinna of dogs and cats, highlighting those unique to this area and noting its role as a common initial site for several conditions; it reports no new results.

In this study, researchers explored ear pinna development in two rodent species and identified that BMP5 plays a crucial role in chondroblast proliferation but not in their initial specification, with implications for understanding tissue differentiation and potential impacts on reconstructive surgery.

In this study, researchers found that CD4 is expressed on murine K5⁺ keratinocytes, and its expression is crucial for maintaining epidermal stem cell balance and wound repair capacity, particularly during aging.

In this study, the authors found that applying hypobaric pressure to the skin significantly increases the transdermal permeation of large molecules by enhancing diffusion, despite the associated skin stretching and hair follicle enlargement not fully explaining this effect.

This review examines the origins and mechanisms of tumor initiation in common skin cancers, but does not present new experimental findings; it emphasizes the need for further research on cancer stem cells.

This study found that keratin 15 lacks the ability to sequester YAP1 in keratinocytes effectively, unlike keratin 14, and suggests that a higher K15:K14 ratio may promote a progenitor state and inhibit differentiation in epidermal keratinocytes.

Only Deomyinae rodents can regenerate complex tissues.

This review discusses autoimmune blistering diseases across species and highlights new treatment efficacy findings and ongoing trials, but it reports no new clinical results.

The researchers reported that DHT may reduce the inflammatory responses induced by C. acnes in androgen-sensitive human sebocyte cells, suggesting a potential link between androgens and infection in sebaceous disorders.

This study found that encapsulated Garcinia mangostana Linn extract in a cream base penetrated more deeply and homogeneously into porcine ear skin compared to other formulations.
