This study found that acne inversa is primarily an epithelial-driven disease, with cyst-forming tendrils causing inflammation due to rupture and the release of debris, highlighting limitations of punch biopsies for analysis.

This study demonstrated that prevascularized human skin constructs containing engineered hair follicles can successfully induce human hair growth when grafted onto mice by promoting blood supply to the grafted skin.

This study reported that canine dermal papilla cells showed a distinct growth pattern and strong collagen IV and laminin staining compared to dermal fibroblasts.

In this study, researchers observed that low levels of fucose-binding lectin staining characterize limbal epithelial progenitor cells, which maintain a high proliferative capacity and may be enhanced by inhibiting fucosylation, offering insights for regenerative therapy of the limbal stem cell niche.

This study investigated the histogenetic relationship between basal cell carcinoma and hair follicles, revealing specific staining patterns of a monoclonal antibody in different skin tissues.

This study found that basal cell carcinoma exhibits altered expression patterns of CD10, p63, BCL-2, and EMA proteins compared to normal skin, with notable differences in staining and reactivity.

This study suggests that Artemis, particularly phosphorylated at serine 516, may have roles in hair follicle growth by influencing differentiation, proliferation, apoptosis, and cell cycling.

This study demonstrates that T-cell responses in extensive alopecia areata scalp may be aberrantly regulated, with reduced cytokine production but activated phenotype, providing insight into the disease's immune mechanisms.

This study found that monoclonal antibodies identified distinct staining patterns in benign and malignant skin appendage tumors, highlighting their potential as markers for analyzing skin tumors.

This study found a significant reduction in Treg cell frequency in alopecia areata compared to other autoimmune and non-autoimmune skin diseases using immunohistochemical staining.

Warts in HIV-positive men can have serious abnormal cell growth, needing careful analysis and treatment to prevent cancer.

This study found that topical treatment with Maneb led to delayed epithelial cell degeneration in hair follicles of rats due to apoptosis.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.

The researchers reported that mast cell and nerve fiber interactions in mouse skin are highly selective for nerve fiber types and vary depending on the hair cycle phase.

This study found that Muse cells retained their pluripotency and ability to differentiate into various cell types even after being cryopreserved multiple times.

This study established methods to isolate, culture, and expand rat hair follicle stem cells, which showed good proliferation and could serve as a cell source for tissue-engineered applications.

In this study, canine hair follicle stem cells were shown to be multipotent, capable of differentiating into various cell types like adipocytes in vitro.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

This study found that diffuse alopecia in HIV-1-infected patients is characterized by higher rates of follicular stem cell apoptosis compared to controls, suggesting a hair cycle disturbance associated with the infection.

The researchers reported that BCE-like changes overlying dermatofibroma show a differentiation pattern most similar to normal basal cells based on specific keratin markers.

This study found that ruby laser hair removal causes microscopic epidermal damage but does not lead to cellular hyperproliferation, unlike ultraviolet-irradiated cell damage.

This study investigated vitamin D receptor expression in normal hair follicles and those affected by alopecia areata, focusing on various markers using immunohistochemical staining.

This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study reports that the monoclonal antibody BKN-1 specifically stained basal cell epithelioma cells and certain normal skin structures, indicating a similarity in keratin expression between the tumor and follicular epithelium below the isthmus portion.

This study found that immunohistochemistry can effectively distinguish between tricholemmoma and basal cell carcinoma, with BerEP4 and CD34 serving as key differentiators.

In this study, mesenchymal stem cell-conditioned medium gel significantly improved wound healing and accelerated hair growth in rats with third-degree burns compared to a placebo, silver sulfadiazine, or no treatment.

This case report describes a rare aggressive variant of squamous cell carcinoma on the scalp of a non-immunosuppressed older male, highlighting its high biological risk for metastasis and poor outcomes.
