Cajal body. Cajal bodies (CBs), also coiled bodies, are spherical nuclear bodies of 0.3–1.0 μm in diameter found in the nucleus of proliferative cells like embryonic cells and tumor cells, or metabolically active cells like neurons. CBs are membrane-less organelles and largely consist of proteins and RNA.
Nuclear bodies (also known as nuclear domains or nuclear dots) are biomolecular condensates, membraneless structures found in the cell nuclei of eukaryotic cells. [1] Nuclear bodies include Cajal bodies, the nucleolus, nuclear speckles (also called splicing speckles), histone locus bodies, and promyelocytic leukemia protein (PML) nuclear bodies ...
Cajal–Retzius cell. Cajal–Retzius cells (CR cells) (also known as horizontal cells of Cajal) are a heterogeneous population of morphologically and molecularly distinct reelin -producing cells. They are found in the marginal zone/layer I of the developing cerebral cortex and in the immature hippocampus of different species and at different ...
Small nucleolar RNA. In molecular biology, small nucleolar RNAs (snoRNAs) are a class of small RNA molecules that primarily guide chemical modifications of other RNAs, mainly ribosomal RNAs, transfer RNAs and small nuclear RNAs. There are two main classes of snoRNA, the C/D box snoRNAs, which are associated with methylation, and the H/ACA box ...
Santiago Ramón y Cajal (Spanish: [sanˈtjaɣo raˈmon i kaˈxal]; 1 May 1852 – 17 October 1934) [1][2] was a Spanish neuroscientist, pathologist, and histologist specializing in neuroanatomy and the central nervous system. He and Camillo Golgi received the Nobel Prize in Physiology or Medicine in 1906. [3] Ramón y Cajal was the first person ...
Interstitial cells of Cajal (ICC) are interstitial cells found in the gastrointestinal tract. There are different types of ICC with different functions. ICC and another type of interstitial cell, known as platelet-derived growth factor receptor alpha (PDGFRα) cells, are electrically coupled to smooth muscle cells via gap junctions, that work ...
Pick one word to describe Republicans and Donald Trump, the focus group moderator asked, and one word to describe Democrats and Kamala Harris. “Crazy,” said the White woman in her 40s, who ...
Centrosome. Cell membrane. The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.
