Centenary of Gaule and Lewin, pioneers in cell counting methodology.
We commemorate the one hundredth anniversary of the publication of a pioneering paper on cell counting, by Gaule and Lewin. Their paper describes a new method for counting cells in tissue sections. First they found the mean number of cell profiles per cell by examining 50 selected cells in serial sections. Then they counted the total number of cell profiles in the ganglion, and finally divided this total profile number by the mean number of profiles per cell. They thought this method more accurate than counting cells by counting only profiles that showed the nucleolus because they noted that a cell's nucleolus sometimes appeared in more than one section and that a single cell could have more than one nucleolus.
