Outline of human anatomy; Cell types. by origin; This is a list of cells in humans derived from the three embryonic germ layers – ectoderm, mesoderm, and endoderm.
LINE1 (an abbreviation of Long interspersed nuclear element-1, also known as L1 and LINE-1) is a family of related class I transposable elements in the DNA of many groups of eukaryotes, including animals and plants, classified with the long interspersed nuclear elements (LINEs). [1]
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...
HeLa (/ ˈ h iː l ɑː /) is an immortalized cell line used in scientific research. It is the oldest human cell line and one of the most commonly used. [1] [2] HeLa cells are durable and prolific, allowing for extensive applications in scientific study.
The terminal cell elongates more than the deeper cells; then the production of a lateral bisector takes place in the inner fluid, which tends to divide the cell into two parts, of which the deeper one remains stationary, while the terminal part elongates again, forms a new inner partition, and so on.
In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells.
