||(Abstract:) "A systematic calculation of the total cell number of the whole human body and of the single organs was carried out using bibliographical and/or mathematical approaches."
||P.468 left column 3rd paragraph: "[Researchers'] current estimation of human total cell number was calculated only on a variety of organs and cell types, as listed in Appendix B, Table B1 (online only, BNID 109708). These partial data correspond to a total number of 3.72±0.81×10^13 (Figure 2 - link ). This number invalidates previous references, at least those indicating 10^12 as the human total cell number and creates the starting point for a complete work that considers all the components of the human body." Note that about 70% of these cells are red blood cells.
