Cross-contamination between cell lines is a longstanding and frequent cause of scientific misrepresentation. Estimates from national testing services indicate that up to 36% of cell lines are of a different origin or species to that claimed. To test a standard method of cell line authentication, 253 human cell lines from banks and research institutes worldwide were analyzed by short tandem repeat profiling. The short tandem repeat profile is a simple numerical code that is reproducible between laboratories, is inexpensive, and can provide an international reference standard for every cell line. If DNA profiling of cell lines is accepted and demanded internationally, scientific misrepresentation because of cross-contamination can be largely eliminated.

Cell culture techniques are invaluable to the modern researcher but difficult to carry out successfully. As part of the series of Handbooks in Practical Animal Cell Biology, this volume offers a concise practical guide to the basic essentials of the technique. Researchers new to cell culture will find a clear explanation of the essential equipment of a tissue culture facility, including tissue culture media and sera. It describes methods for growing suspension and adhesion cultures, including how to store cells and prepare primary cultures from cells. For those already culturing cells, the handbook will act as a handy reference to the basic techniques. The essence of the book is to deal with the generalities of cell culture to give a grasp of the basic concepts before involvement in more specialized work in the field. Ideal for anyone moving into tissue cell culture techniques or looking for a concise reference book.
