Conserved, multimeric protein complexes that promote and modulate the formation of asymmetric cellular architecture in diverse tissue types and organisms. Planar cell polarity (PCP). The polarization of epithelial cells along the plane of the epithelium, orthogonal to the apico–basal axis, directing th...
细胞和有机体生物学BIOL10004Biology of Cells and Organisms: 课程内容: 本课程的目标是让学生熟悉细胞和有机体生物学的现代概念,涵盖了以下关键主题:多细胞生物体的结构和功能,涉及细胞功能、能量转化系统、营养、水吸收、排泄、气体交换、循环和免疫反应;植物和动物的繁殖和发育;涉及反应和协调的机制,如植物和动物的...
Cells of organisms have been studied for hundreds of years. Organisms are entirely made up of cells, thus making it a worldwide unit of life. An organism is any living thing, whether it is a plant, an animal or fungi. Some organisms (known as simple organisms) are composed of only one...
Lysosomes also use their hydrolytic enzymes to destroy disease-causing organisms that might enter the cell. A good example of this occurs in a group of white blood cells called macrophages, which are part of your body’s immune system. In a process known as phagocytosis, a section of the pl...
1. Genes with closely related homologs in cellular organisms (typically, the host of the given virus) present in a narrow group of viruses. 2. Genes that are conserved within a major group of viruses or even several groups and have relatively distant cellular homologs. Virus-specific genes ...
These junctions play a prominent role in maintaining the integrity of tissues in multicellular organisms and some, if not all of them, are involved in signal transduction . Intercellular junctions and hemidesmosomes were first identified in tissues examined by electron microscopy. In contrast, the ...
Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.eBooks This page appears in the following eBook Essentials of Cell Biology, Unit 1.2 Cell Biology for ...

Somitogenesis has been well characterized in model organisms, resulting in detailed description of the somite segmentation clock. Here they generate somitogenic organoids from human pluripotent stem cells that recapitulate somitogenesis, periodic segmentation, and proper polarity. ...
