... Taurine (2-aminoethanesulphonic acid) is a semi-essential amino acid, which is not incorporated into proteins. In mammalian tissues, taurine is ubiquitous and is the most abundant free amino acid in the heart, retina, skeletal muscle, brain, and leukocytes, exhibiting multiple functions and tissue-p ...

... lineage tracers leak from one macromere into the others during stages 7–8. We have now found that the fusion of the macromeres occurs in a two-step process with a set time course. The first step is the fusion of A′′′ and B′′′ to form a cell we designate as A/B. When we injected β-galactosidase into ...

Cell culture



Cell culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment. In practice, the term ""cell culture"" now refers to the culturing of cells derived from multicellular eukaryotes, especially animal cells, in contrast with other types of culture that also grow cells, such as plant tissue culture, fungal culture, and microbiological culture (of microbes). The historical development and methods of cell culture are closely interrelated to those of tissue culture and organ culture. Viral culture is also related, with cells as hosts for the viruses. The laboratory technique of maintaining live cell lines (a population of cells descended from a single cell and containing the same genetic makeup) separated from their original tissue source became more robust in the middle 20th century.
