The ciliated human keratinocyte
Journal of Ultrastructure Research, 1984Human keratinocytes were investigated for the presence of single cilia. Almost all basal keratinocytes were found to carry a single cilium in normal, occluded, and psoriatic skin. The ciliary structure was progressively reduced in keratinocytes approaching the surface. No remnants of the ciliary apparatus were found in the granular layer.

CILIATED ADENOCARCINOMA OF THE ENDOMETRIUM
Acta Obstetricia et Gynecologica Scandinavica, 1985Abstract. Two cases of ciliated endometrial adenocarcino‐ma which came to attention in less than one year are described. This entity deserves emphasis, as its ciliation may distract from its histological malignant features. Association of cilia with atypical nuclear features in the same cell is the diagnostic characteristic which distinguishes it from

Karyorelict ciliates have near diploid somatic nuclei (macronuclei) incapable of division. If selective pressure favors nuclear division, how could such macronuclei have evolved? I propose that they initially evolved in the context of a diplophase stage that consisted entirely of a non-dividing trophont that was terminated by the induction of meiosis ...

Control of ciliation in embryogenesis
Nature Cell Biology, 2015The protrusion of cilia into extracellular space provides cells with sensors of localized environmental cues that include fluid flow, mechanical force and important growth factors such as Hedgehog. Live imaging has now captured the initial appearance of cilia during embryogenesis, and defined lineage-specific determinants that restrict extra-embryonal ...

Ciliated Carcinoma of the Endometrium
International Journal of Gynecological Pathology, 2020We report a case of ciliated carcinoma of the endometrium in a 55-yr-old woman with stromal hyperthecosis of the ovaries. The patient presented with postmenopausal uterine bleeding and an endometrial curetting revealed an atypical epithelial proliferation that met the criteria for endometrioid adenocarcinoma notwithstanding an abundance of ciliated ...

Abstract The occurrence of cilia in endometrim that is normal, hyperplastic, atrophic, and adenocarcinomatous has been studied. Cilia are frequent in normal cyclic endometria and in hyperplastic endometria, are less frequent in those exhibiting atrophy, and are rare in carcinomatous endometria.

Abstract Balantidium coli belongs to the phylum Ciliophora of the kingdom Protista, which comprises all protozoa with cilia and mitochondria with tubular, often curved cristae, which in anaerobic species may be replaced by hydrogenosomes (Corliss, 1994).

Ectosymbiosis in Ciliated Protozoa
2001The picture of the ectosymbiotic associations between ciliates and bacteria that can be drawn from this paper is complex, although, in all likelihood, it is far from complete: other different, as yet undiscovered relationships may exist. From the ecological point of view these kinds of associations certainly contribute to the differentiation of the ...

The Breakpoint Graph in Ciliates
2005The gene assembly process in ciliates (single-cell organisms) is interesting from both the biological and computational point of view. This paper studies the computational nature of the gene assembly process. Motivated by the breakpoint graph known from another branch of DNA transformation research, we introduce the reduction graph as a tool for the ...

Intracellular bacteria in ciliates
International Microbiology, 2001Ciliates are frequently colonized by other micro-organisms. The large size of ciliate cells offers habitats for hundreds to thousands of bacteria in different compartments, such as cytoplasm, nuclei and even perinuclear spaces. Size, phagocytic feeding habit and other features appear to be favorable pre-adaptations of ciliates for symbiosis with ...
