DEFINITION

Classification: 435/325

ANIMAL CELL, PER SE (E.G., CELL LINES, ETC.); COMPOSITION THEREOF; PROCESS OF PROPAGATING, MAINTAINING OR PRESERVING AN ANIMAL CELL OR COMPOSITION THEREOF; PROCESS OF ISOLATING OR SEPARATING AN ANIMAL CELL OR COMPOSITION THEREOF; PROCESS OF PREPARING A COMPOSITION CONTAINING AN ANIMAL CELL; CULTURE MEDIA THEREFORE:

(under the class definition) Subject matter including animal cells, per se; compositions containing animal cells; processes of in vitro propagation of animal cells or groups of cells that are not organized tissues; processes of maintaining or preserving animal cells or compositions thereof; processes of isolating or separating an animal cell or composition thereof; processes of preparing a composition containing animal cells; culture media therefore.

(1) Note. Where the tissue is first cultured and then destroyed by subsequent extraction, for example to extract compound or composition from the tissue, the process is not included in this subclass. Such subject matter is provided for in subclasses 41+ of this class.

(2) Note. This subclass provides for the culture of skin cells for a purpose such as transplantation.
