The most complete resource on the techniques, equipment, principles, and practices of animal cell culture, this text offers a complete background related to growth of animal cells in culture.
Because of the continuing expansion of cell culture, and to keep the bulk of the book to a animal biotechnology by freshney size, some specialized protocols are presented as supplementary material online.
Also, care must be taken to avoid the recurrent problem of cross-contamination and to authenticate stocks.
Culture of Animal Cells: A Manual of Basic Technique, 5th Edition
Hence, tissue culture should not be undertaken casually to run one or two experiments. A realistic maximum per batch for most small laboratories with two or three people doing tissue culture might be 1—10 g of cells. With a little more effort and the facilities of a larger laboratory, 10— g is possible; above g animal biotechnology by freshney industrial pilot-plant scale, a level that is beyond the reach of most laboratories but is not impossible if special facilities are provided, when kilogram quantities can be generated.
The cost of producing animal biotechnology by freshney in culture is about 10 times that of using animal tissue.

Semimicroor microscale assays can often be quicker, because of reduced manipulation times, volumes, centrifuge times, etc.
This effect was blamed on dedifferentiation, a process assumed to be animal biotechnology by freshney reversal of differentiation, but later shown to be largely due to the overgrowth of undifferentiated cells of the same or a different lineage.
The development of serum-free selective media see Section Stable markers are required for characterization of the cells see Section Even with short-term cultures of untransformed cells, heterogeneity in growth rate and the capacity to differentiate within the population can produce variability from one passage to the next see Section Specific cell interactions characteristic of the histology of the tissue are lost, and, as the cells spread out, become mobile, and, in many cases, start to proliferate, so the growth fraction of the cell population increases.
When a cell line forms, it may represent only one or two cell types, and many animal biotechnology by freshney cell—cell interactions are lost.
The culture environment also lacks the several systemic components involved in homeostatic regulation in vivo, principally those of the nervous and endocrine systems. Without this control, cellular metabolism may be more constant in vitro than in vivo, animal biotechnology by freshney may not be truly representative of the tissue from which the cells were derived.
Recognition of this fact has led to the inclusion of a number animal biotechnology by freshney different hormones in culture media see Sections Energy metabolism in vitro occurs largely by glycolysis, and although the citric acid cycle is still functional, it plays a lesser role.

It is not difficult to find many more differences between the environmental conditions of a cell in vitro and in vivo see Section Still, although the existence of such differences cannot be denied, many specialized functions are expressed in culture, and as long as the limits of the model are appreciated, tissue culture can become a very valuable tool.
Toward this end, the tissue is cultured at the liquid—gas interface on a raft, grid, or gelwhich ORGAN CULTURE Tissue at gas-liquid interface; histological structure maintained Tissue at solid-liquid interface; cells migrate to form outgrowth favors the retention of a spherical or three-dimensional shape.
Because of the retention of cell interactions found in the tissue from which the animal biotechnology by freshney was derived, organ cultures tend to retain the differentiated properties of that tissue.
