This study identified differentially expressed microRNAs between back and belly skin in Rex rabbits, highlighting their potential roles in skin development processes.

This study reports that skin bacteria can accelerate hair follicle regeneration and improve wound healing through IL-1β signaling, by activating keratinocytes in a pathway involving IL1R/Myd88.

This animal study found that dermal papilla cells in hair follicles of chimeric mice can originate from various fibroblasts in the skin, challenging assumptions about their specific lineage.

In this study, researchers examined skin growth and quality in Pekin ducks from 1 to 6 weeks of age, finding that skin factors like strength and collagen content increased with age and were influenced by gene expressions related to cell proliferation and collagen synthesis.

This study found that, in mice, different precursor populations give rise to Merkel cells in hairy versus glabrous skin, but their formation is controlled by a common genetic program involving FGFR2 signaling.

This study found that a large number of pelage hair follicle mesenchymal stem cells can be efficiently isolated using two-step Ficoll Density Gradient Sedimentation, promoting hair growth by secreting exosomes in mice.

This study reported that pelage hair follicle mesenchymal stem cells isolated from mice using Ficoll Density Gradient Sedimentation can be obtained in large numbers and may promote hair growth via exosome secretion.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

This study found that GFRα2 influences cell size but not survival or target innervation of Ret-positive low-threshold mechanoreceptors in mouse dorsal root ganglia, differing from its role in nonpeptidergic nociceptors.

This study found that splenic melanosis in C57BL/6 mice is associated with synchronized skin melanization during hair cycles, but decreases with age.

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 reported that Dkk4-knockout mice showed disrupted hair follicle patterning, suggesting a WNT-DKK axis may influence regional specificities in hair follicle induction related to androgenetic alopecia.

This study found that the combined oral contraceptive containing ethinyl estradiol and chlormadinone acetate was effective in reducing moderate papulopustular acne and other androgen-related skin disorders compared to placebo.

This review discusses the design strategies and applications of long-acting polymeric microneedles, noting their potential to improve patient compliance and reduce side effects in chronic disease management, but reports no new experimental results.

This review discusses human hair follicle development and highlights the potential of creating human in vitro models and skin substitutes with hair follicles, reporting no new clinical results.

This study found that Brandt's hedgehog has the thickest skin on its back and the thinnest on the cloacal region, with sebaceous and sweat glands primarily located in the nostril area.

This study observed significant differences in immune cell infiltration and gene expression across different skin sites, with the back displaying higher tolerance-promoting immune mechanisms, which may enhance epicutaneous immunotherapy outcomes.

This report from the International Journal of Dermatology highlights their commitment to diversity and equity in the dermatology field, emphasizing representation in research for individuals with skin of color and discussing their record-breaking submission year with global participation.

This study observed that dermal dendritic cells migrate to the epidermis in mouse tail and back skin, correlating with changes in epidermal physiology like ortho- and parakeratosis.

This study examined the skin structure of European Brown Bears, finding that the thickest skin is on the back and the thinnest on the ventral abdomen, with distinct layers and fiber networks.

In this study, researchers observed that abdominal wounds in laboratory rats healed faster, completing epithelialization in 20 days versus 30 days for back wounds, possibly due to a higher expression of skin stem cell marker genes in the abdominal area.

This clinical report details the case of a 22-year-old man experiencing severe pustular eruptions on his chest and back, which improved after increasing minocycline to 100 mg twice daily.

In this case report, a 6-year-old spayed female Samoyed dog presented with non-pruritic alopecia and hyperpigmentation on the hips and back, with unremarkable bloodwork and negative Cushing's disease and skin tests.

In this study, the researchers reported the detailed anatomical structure of horse skin, including the composition and organization of the epidermis, dermis, and associated glands and follicles.

This study found that transplanting GFP transgenic tail skin onto wild-type mice leads to partial replacement of dermis, nerves, and blood vessels by recipient tissue after six months, while epidermis, hair follicles, and sebaceous glands persist from the graft.

This study translated and culturally adapted the Skindex-16 questionnaire into Arabic, finding it to be a reliable and valid measure of quality-of-life impacts from skin diseases in Saudi patients.

In this study, hair color changes in piebald rats after skin grafting suggest that such changes are more likely due to the surgical process than the new environment.

This study found that by using an automated system to analyze skin histology, 108 structural features were significantly affected by age, and it identified four new aging biomarkers and notable sex-based differences in skin aging.

This study investigated the effects of 10600nm CO2 dot laser and Nd: YAG laser on Wistar rats' skin, finding that CO2 laser treatment resulted in higher positive expression of MMP-1 and TIMP-1 compared to Nd: YAG laser, with statistically significant differences noted.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.
