The ghosts of HeLa: How cell line misidentification …
WebIf a cell line is thought to be contaminated, it is usually tested for authenticity. The widespread contamination of HeLa cells was initially recognized by Walter Nelson-Rees using simple Giemsa stain karyotyping under a light microscope. This technique works well in recognizing HeLa because these cells have distinctive chromosome aberrations. WebNo story exemplifies cellular contamination better than the HeLa saga. In the 1960s, a researcher discovered that 100% of that era's commonly used cell lines had been incidentally replaced with cells from the Henrietta Lacks cell line. As that anecdote illustrates, widespread cellular contamination can occur through cross-contamination … gurps boxing
