450-480 / 1000+ resultsresearch 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 Identification of somatic and germline mosaicism for a keratin 5 mutation in epidermolysis bullosa simplex in a family of which the proband was previously regarded as a sporadic case
The keratin 5 mutation in a family with epidermolysis bullosa simplex was due to mosaicism, not a new mutation.
research Delayed Cutaneous Wound Healing and Aberrant Expression of Hair Follicle Stem Cell Markers in Mice Selectively Lacking Ctip2 in Epidermis
Lack of Ctip2 in skin cells delays wound healing and disrupts hair follicle stem cell markers in mice.
research Hair follicle epithelial stem cells contribute to interfollicular epidermis during homeostasis
Hair follicle stem cells help maintain skin health by moving to and supporting the skin's surface layers.
research Stem Cell Heterogeneity and Plasticity in Epithelia
Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
research Compartmentalized Epidermal Activation of β-Catenin Differentially Affects Lineage Reprogramming and Underlies Tumor Heterogeneity
Activating β-catenin in different skin stem cells causes various types of hair growth and skin tumors.
research Hair Cycle-Dependent Changes in Skin Immune Functions: Anagen-Associated Depression of Sensitization for Contact Hypersensitivity in Mice
research Hypomyelinating leukodystrophy-10 presenting with an additional atypical feature of increased body hair and Mongolian spots
HLD10 can include increased body hair and Mongolian spots.
research Long‐term culture of skin biopsies: maintenance of fibroblast production and competency of reprogramming
Long-term skin biopsy cultures can produce many fibroblasts that remain functional and can be reprogrammed.
research 85 Primary cutaneous follicle center lymphoma spans yet unrecognised subtypes including polyclonal reactions
PCFCL may have unrecognized subtypes and needs more research.
research One Transgene: Two Outcomes
Modified β-catenin can cause different effects in mouse skin cells, leading to cysts or tumors depending on the cell type.
research P381 Kinetics of Titan cells generation and transcriptome modifications comparing three in vitro protocols
Three different methods were compared for creating Titan cells, a type of fungus cell. The OZ method made the most cells initially, but the number dropped quickly. The EB method also made a lot of cells, but the number also dropped. The AA method made fewer cells, but the number stayed steady. The methods also affected which genes were active in the cells.
research Dysfunction of keratinocyte adhesion
Keratinocyte adhesion problems can cause skin and hair disorders.
research Behavior of Human Foreskin Keratinocytes Expressing a Hair Follicle Stem Cell Marker CD200
CD200 is not a reliable marker for identifying stem cells in all skin types.
research Decision letter: Interplay of opposing fate choices stalls oncogenic growth in murine skin epithelium
Skin cells can naturally limit the growth of cancerous changes by balancing cell renewal and differentiation.
research Heterozygous Arrhythmogenic Cardiomyopathy-desmoplakin Mutation Carriers Exhibit a Subclinical Cutaneous Phenotype with Cell Membrane Disruption and Lack of Intercellular Adhesion
Carriers of a specific gene mutation have subtle skin changes without visible symptoms.
research A Possible Role of Keratinocytes of Skin and Mucous Membranes in Prion Propagation and Transmission
Skin cells might help spread prion diseases like Creutzfeldt-Jakob disease.
research The Phenotypic and Genotypic Spectra of Ichthyosis With Confetti Plus Novel Genetic Variation in the 3′ End ofKRT10
Ichthyosis with confetti is a genetic skin disorder with consistent ectodermal malformations and various KRT10 gene mutations.
research Lineage potential, plasticity and environmental reprogramming of epithelial stem/progenitor cells
Environmental cues can change the fate and function of epithelial cells, with potential for cell therapy.
research Clinical Snippets
A bull with a gene mutation was asymptomatic, synthetic retinoids cause hair loss, and new therapeutic targets were identified for skin diseases.
research Merkel cell polyomavirus infection and persistence modelled in skin organoids
Merkel cell polyomavirus can infect and persist in skin cells, evading the immune system, but certain treatments can control it.
research The Anagen Hair Cycle Induces Systemic Immunosuppression of Contact Hypersensitivity in Mice
Hair growth phase in mice weakens certain immune responses.

Skin cell behavior is influenced by the tightness of nearby cells, affecting their growth and development.
research 708 Polycomb-mediated repression and Sonic hedgehog signaling regulate Merkel cell specification
Sonic hedgehog signaling is needed for the development of touch-receptor cells in the skin, and the loss of Polycomb repressive complex 2 can lead to more of these cells.
research Aged differentiated cells reverse into native stemness-like state by niche cytokines to sustain lifelong homeostasis and tissue repair
Aged corneal cells can revert to a stem-like state to help repair tissue.
research Loss of Ten1 in mice induces telomere shortening and models human dyskeratosis congenita
Loss of Ten1 in mice causes telomere shortening and symptoms similar to human dyskeratosis congenita.
