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

In this study, researchers documented the immunohistochemical distribution of CD34 in basal cell carcinoma and found distinct patterns of CD34 expression, with variations in CD34 positivity between different areas of BCC tumor stroma and adjacent skin regions.

Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.

This study introduces a modular fiber model to investigate how changes in microstructural properties of wool affect its critical buckling load, highlighting potential uses and areas needing further research in wool fiber biophysics.

This study identified and sequenced several keratin cDNA clones showing distinct expression patterns in mouse epithelia, with in situ hybridization highlighting differences in keratin distribution between normal and hyperproliferative tissues.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This study found that mutations in phosphorylation sites on the PIN3 protein disrupt its phosphorylation and subcellular trafficking, affecting auxin transport and root growth in a cell-type-specific manner.

The study found that, unlike in actinic keratosis and squamous cell carcinoma, basal cell carcinoma tissues showed higher expression of nidogen1 and Col4 in both basement membranes and surrounding stroma compared to normal skin.

This article reviews the characteristics and presentation of fibrosing alopecia in a pattern distribution, a form of scarring alopecia similar to androgenetic alopecia and lichen planopilaris, but provides no new clinical findings.

This study found that in mice, type XVII collagen is essential for controlling epidermal cell proliferation through Wnt signaling, with its deficiency or altered distribution leading to skin hyperproliferation and aging-like changes.

In this study, researchers found that women with telogen effluvium had lower MCV/RDW ratios, MPV, and ferritin levels compared to healthy controls, suggesting iron deficiency's involvement in this chronic hair loss condition.

This review summarizes the cell type distribution and functional significance of human keratins, emphasizing their roles in tumor diagnosis and potential clinical applications, and reports no new clinical findings.

This study found that poly(adenosine diphosphate-ribose) synthesis in human skin varies by cell type and condition, with distinct patterns in psoriatic, cancerous, and normal tissues.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.

This study found that ERBB2 mutations and amplifications are likely key drivers of extramammary Paget disease, suggesting potential for targeted therapies and cancer immunotherapy due to the moderately high mutational load observed.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study suggests that the absence of alpha5(IV)/alpha6(IV) chains in certain subepidermal basement membrane spots may relate to interactions with melanocytes in human skin.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This review discusses the impaired functionality of regulatory T cells in the pancreas during the development of Type 1 diabetes, highlighting their role in disease pathogenesis, potential of Treg-based therapies, and challenges in clinical applications.

Antisense oligonucleotides show promise for treating Myotonic Dystrophy type I.

This case study in a renal transplant patient observed that eruptive KA-type SCCs exhibited aggressive behavior and genetic expression changes following intralesional chemotherapy, indicating potential caution against routine use of such treatments in similar cases.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibits 5α-reductase type 1, reducing 5α-DHT production by 52% in a cell-based assay with human hair dermal papilla cells.

This study introduced RoPod, a customizable tool for low-stress live imaging of Arabidopsis roots, which improves data reproducibility and provides new insights into plant autophagy by revealing detailed, cell type-specific responses to chemical modulators.

This study examined the molecular communication in psoriasis cells, highlighting unique immune cell interactions and identifying new features of the hair follicle cell-psoriasis axis. It suggests the potential for targeted therapies at the single-cell level to improve psoriasis treatment.

This study found that most completely excised basal cell carcinomas in the head and neck were nodular, with a 2.7% recurrence rate, particularly in median areas, likely due to anatomical and histopathological factors.

In this case report, a 21-year-old female with familial partial lipodystrophy type 2 and hyperandrogenism was found to have a rare Sertoli cell tumor of the ovary, highlighting an unusual presentation where links between these two rare conditions are still unknown.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

This study found that melatonin treatment increased epidermal thickness, subcutaneous fat, and dermal-related factors in postmenopausal rats, suggesting benefits for skin structure after menopause.
