Early Embryonic Development
... Stem cells vary in their potency: Totipotent: can give rise to any cell and so can produce a whole organism Pluripotent: potential to develop into many cell types but not all of them. Multipotent: cells retain the capacity to make a few types of cell Unipotent: make one type of cell e.g. Skin cells ...

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.
