For example, supposed thyroid lines were actually melanoma cells, supposed prostate tissue was actually bladder cancer, and supposed normal uterine cultures were actually breast cancer. [1] This is a list of cell lines that have been cross-contaminated and overgrown by other cells.
Primary cell culture is the ex vivo culture of cells freshly obtained from a multicellular organism, as opposed to the culture of immortalized cell lines.In general, primary cell cultures are considered more representative of in vivo tissues than cell lines, and this is recognized legally in some countries such as the UK (Human Tissue Act 2004). [1]
Cell culture is a fundamental component of tissue culture and tissue engineering, as it establishes the basics of growing and maintaining cells in vitro. The major application of human cell culture is in stem cell industry, where mesenchymal stem cells can be cultured and cryopreserved for future use. Tissue engineering potentially offers ...
HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...
Colon cancer: In a study to understand the effects of Mycoplasma contamination on the quality of cultured human colon cancer cells, a positive correlation was found between the number of M. hyorhinis cells present in the sample and the percentage of CD133-positive cells (a glycoprotein with an unknown function).

Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [2] was an African-American woman [5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [B] and one of the most important cell lines in medical research.
Causes of melanoma. Ultraviolet light exposure from the sun or from tanning beds causes most melanomas. Melanoma may appear at a spot where you have an existing mole. But if an unusual spot shows ...
The alternative, performing an analysis on primary cells from multiple tissue donors, does not have this advantage. [citation needed] Immortalised cell lines find use in biotechnology, where they are a cost-effective way of growing cells similar to those found in a multicellular organism in vitro.
