In this case study, researchers describe a rare instance of pilomatricoma with ossification in a 32-year-old woman, highlighting specific histopathological features and the role of bone morphogenic proteins and macrophages in its development.

This study found that neural crest-derived hair follicle cells in mice can differentiate into osteoblast-like cells, suggesting a potential application for bone regenerative therapies.

In this study, researchers observed that Melan A, a melanocytic marker, was significantly expressed in hair follicles of alopecia areata patients and correlated with immune infiltrates, suggesting melanocytes might contribute to the autoimmune response in this condition.

This study found that the enzyme Acer1 plays a crucial role in skin health and tumor prevention by regulating ceramide metabolism in mice.

This study found that trichoblastomas and nodular basal cell carcinomas have similar cytokeratin expression patterns, indicating differentiation towards the outer root sheath epithelium.

This study presents two new mouse models using the CreER T2-loxP system to target and study melanocytic cells, with implications for melanoma research.

This study found that Merkel cell hyperplasia is specific to certain skin diseases and not related to general epidermal proliferation.

This study found that the patchwork mutation in mice affects melanocyte survival in hair follicles, leading to a variegated coat pattern without partially pigmented hairs due to a community effect among melanoblasts.

This study suggests that 3D spheroid cultivation of dermal papilla cells can restore their hair-inductive capabilities, which are lost in 2D-cultured cells.

The study examined cytokeratin expression in different bovine epithelial tissues, finding that hair follicles and nasolabial glands express both acidic and basic types, while other epithelia express only one type.

This study found that inhibiting AP-1 activity in mice modified tumor development, leading to transdifferentiation between squamous and sebaceous tumors, with molecular analysis suggesting AP-1's role in maintaining tumor cell identity.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

In this study, researchers found that bone marrow-derived epithelial cells significantly contribute to the development of cutaneous tumors and dysplastic ulcers in mice, indicating a potential systemic role in skin cancer development.

This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study identified that copper depletion in dermal papilla cells reduced hair growth by boosting ROS levels, but ROS scavengers like NAC and ascorbic acid partially alleviated this effect.

This study suggests that keratin expression in keratoacanthomas resembles that in the upper part of hair follicles, implying a potential origin, but it is indistinguishable from squamous cell carcinomas in terms of keratin reactivity.

This study describes "alarm reaction" histologic changes in pilosebaceous structures, including regression of hair matrix and alterations in sebaceous glands, affecting follicular and sebaceous gland morphology.

This study concluded that label-retaining cells in mouse epidermis differ in their sensitivity to proliferative stimuli, influencing their division and potential transdifferentiation without consistently depleting their population.

This review discusses melanocyte biology and its genetic and molecular basis, highlighting its relevance in understanding diseases like vitiligo and albinism, and reports no new findings.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This case study reports a peculiar variant of an epidermal cyst in a patient, featuring unique characteristics like brownish, lumpy contents resembling bone marrow.

This study found that Notch signaling is crucial for maintaining proper melanocyte distribution and preventing premature differentiation in the melanocyte lineage within hair follicles.

This study found that overexpressing the PML protein in transgenic mice decreased skin tumor occurrence and delayed their progression, highlighting PML's potential role in influencing keratinocyte growth and differentiation.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

This study found that in superficial angiomyxomas, S100A4-positive mesenchymal niches may induce non-neoplastic adnexal epithelial growth, and highlighted evidence of mesenchymal-to-epithelial transition in eccrine duct branching, especially in Carney's complex cases.

This study found that keratin immunohistochemistry suggests neoplastic cells in eccrine and apocrine poromas are closely related to dermal sweat duct cells, but cannot differentiate these poromas based solely on keratin patterns.

This study identified a novel MTS24-positive murine keratinocyte population with increased colony-forming ability, suggesting these cells may serve as a new reservoir of proliferative progenitor or stem cells in hair follicles.

This study found that anagen stage protein homogenates and specific epitopes from melanogenesis proteins activated CD8 T cells, suggesting alopecia areata is an anagen-specific disease.
