Single-cell RNA sequencing (scRNA-seq) allows the creation of large collections of individual cells transcriptome. Unsupervised clustering is an essential element for the analysis of these data, and it represents the initial step for the identification of different cell types to investigate the cell subpopulation organization of a sample.

Programming Cell–Cell Communications with Engineered Cell Origami Clusters
Journal of the American Chemical Society, 2020Cells existing in the form of clusters often exhibit distinct physiological functions from their monodispersed forms, which have a close association with tissue and organ development, immunoresponses, and cancer metastasis. Nevertheless, the ability to construct artificial cell clusters as in vitro models for probing and manipulating intercellular ...

Mast cells in cluster headache
Acta Neurologica Scandinavica, 2009Temporal skin biopsies were performed in six cluster headache patients and controls. In biopsies, mast cells were examined by light and electron microscopy for possible deviations in number, distribution and morphology. Three patients were in a headache phase, the other three in a headache-free interval.

Ceramide and cell death receptor clustering
Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2002Acid sphingomyelinase (ASM) has been shown to be activated by a variety of receptor molecules and stimuli including CD95, the tumor necrosis factor receptor (TNF-R), CD40, CD28, LFA-1, CD5, during development, irradiation, heat shock, UV light or bacterial and viral infections.

Glycosphingolipid Clustering and Mast Cell Degranulation
International Archives of Allergy and Immunology, 1981It was shown using spin-labelled probes that challenge of sensitized rat peritoneal mast cells results in clustering of sphingolipids located in the outer leaflet of the plasma membrane bilayer. This clustering is partially inhibited by antiallergic drugs of the chromone type.

Luminescent Cell-Penetrating Pentadecanuclear Lanthanide Clusters
Journal of the American Chemical Society, 2013A novel pentadecanuclear lanthanide hydroxy cluster [{Ln15(μ3-OH)20(PepCO2)10(DBM)10Cl}Cl4] (Ln = Eu (1), Tb (2)) featuring the first example with peptoids as supporting ligands was prepared and fully characterized. The solid-state structures of 1 and 2 were established via single-crystal X-ray crystallography. ESI-MS experiments revealed the retention

Supraependymal cell clusters in the rat hypothalamus
Anatomy and Embryology, 1983The fine structure of supraependymal cell clusters of the median eminence was studied with TEM. The cluster cells were identified on the basis of ultrastructure and histochemical determination of glial fibrillar acidic protein (GFA). The phagocytic properties were also studied by means of intraventricular injections of HRP. Neurons, neuroglia cells and

Clustering-Based Touching-Cells Division
2011 Eighth Web Information Systems and Applications Conference, 2011Automated cell segmentation of microscopy cell images play an important role in various applications of cell images analysis. Nowadays, the automated methods for cell segmentation is still challenging in situations, not only the fuzzy microscopy cell images but also where there might be touching cells.

Cell and Cell-Cluster Models for Liquids
The Journal of Chemical Physics, 1956The theory of the cell model is developed in its most general form, allowing an arbitrary volume and a variable number of occupants to each cell. Kirkwood's principle of minimizing the free energy is used to determine the best cell distribution functions and thermodynamic functions.
