180-210 / 1000+ results research Rippled‐pattern trichomatricoma
A unique hair tumor with a rippled pattern was identified, showing incomplete differentiation and unusual cell arrangements.
research 560 Isolation of an “early” transit amplifying keratinocyte population in interfollicular human epidermis: a role for CD271 receptor
Scientists found a new type of skin cell that could help with skin repair and these cells work better with a certain protein.
research The clinicopathological spectrum of trichoepitheliomas: a retrospective descriptive study
Trichoepitheliomas can be hard to distinguish from other skin conditions and often start in teenage years.
research Severe follicular hyperplasia and spontaneous papilloma formation in transgenic mice expressing theneu oncogene under the control of the bovine keratin 5 promoter
ErbB2 signaling is crucial for skin cell growth and cancer development in mice.
research Human hair follicle and interfollicular keratinocyte reactivity to mouse HPV16-transformed cells: An in vitro study
HPV16-transformed cells can change human skin cell properties, aiding tumor growth.
research Analysis of proliferation, apoptosis and keratin expression in cultured normal and immortalized human buccal keratinocytes
SVpgC2a cells show abnormal growth and keratin changes, modeling early cancer development.
research The ultrastructure of the interfollicular epidermis of the hairless (hr/hr) mouse
research Merkel Cells in Hyperplastic and Neoplastic Lesions of the Skin
Merkel cell increase is specific to certain skin diseases, not general skin growth.
research Upregulation of the truncated basic hair keratin 1(hHb1‐ΔN) in carcinoma cells by Epstein‐Barr virus (EBV)
EBV infection increases a specific keratin variant in carcinoma cells, possibly affecting cell structure and cancer progression.
research Kinetic topographical heterogeneity in follicular thyroid neoplasms and growth patterns
Different growth patterns in thyroid tumors are influenced by where cell growth and death occur.
research Differentiation of the basal cell epithelioma-like changes overlying dermatofibroma.
Basal cell epithelioma-like changes are most similar to normal basal cells.
research Expression patterns of hair and epithelial keratins and transcription factors HOXC13, LEF1, and β‐catenin in a malignant pilomatricoma: a histological and immunohistochemical study
The malignant pilomatricoma showed strong epithelial keratin expression, suggesting it may not calcify.
research Defining compartmentalized stem and progenitor populations with distinct cell division frequency in the ocular surface epithelium
Stem and progenitor cells in the eye have different division rates and locations, affecting how they respond to injury.
research Evidence of proliferative activity in human Merkel cells: implications in the histogenesis of Merkel cell carcinoma
research Expression of E6 and E7 papillomavirus oncogenes in the outer root sheath of hair follicles extends the growth phase and bypasses resting at telogen.
E6/E7 oncogenes in hair follicles cause continuous hair growth by skipping the resting phase.
research Deregulated expression of E2F1 induces hyperplasia and cooperates with ras in skin tumor development
Overexpression of E2F1 can lead to skin tumors and disrupt hair growth.
research Transduction‐induced overexpression of Merkel cell T antigens in human hair follicles induces formation of pathological cell clusters with Merkel cell carcinoma‐like phenotype
Overexpressing Merkel cell virus proteins in human hair follicles can create clusters of cells that resemble Merkel cell cancer.
research Epithelial-Stromal Interactions in Basal Cell Cancer: The PDGF System
research Interparietal nodule in a 49‐year‐old woman
A rare scalp tumor was removed from a 49-year-old woman, with a good outlook if benign but needing careful monitoring if malignant.
research Differential epithelial outgrowth of plucked and microdissected human hair follicles in explant culture
research Differential epithelial outgrowth of plucked and microdissected human hair follicles in explant culture
research Linear trichoepithelioma on the neck of a 15-year-old girl
A 15-year-old girl has a benign skin tumor on her neck.
research β1 Integrin Signaling Maintains Human Epithelial Progenitor Cell Survival In Situ and Controls Proliferation, Apoptosis and Migration of Their Progeny
β1 integrin is essential for the survival, growth, and movement of human epithelial progenitor cells.
research “Dark Cells” in Normal, Hyperplastic, and Promoter-Treated Mouse Epidermis Studied by Conventional and High-Voltage Electron Microscopy
research LB1019 The early region of trichodysplasia spinulosa polyomavirus drives proliferation, altered differentiation, and ectopic expression of hair follicle differentiation markers in interfollicular tail epidermis
The early genes of a specific virus can cause abnormal skin cell growth and hair follicle changes.
research Ability of Transplanted Cultured Epithelium to Respond to Dermal Papillae
Cultured epithelium can form hair follicles when combined with dermal papillae.
research Immunolocalization of telomerases in human hairs identifies proliferating cells in the bulb matrix and outer root sheath
Telomerase-positive cells are mainly in the bulb matrix and outer root sheath of hair follicles.
research Pathologic Quiz Case: A Nodule on the Back
The nodule on the woman's back was a benign hair follicle tumor, not cancer, but needed removal.
research LB1081 Three-dimensional imaging of tight junction-network across multiple layers of human epidermis by array tomography using backscattered electron-mode scanning electron microscopy
The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.
