P.63 right column bottom paragraph: "The extent of the daily cellular renewal is of an amazing magnitude. The investigation of the physiology and pathophysiology of cellular renewal was made
possible by the extensive use of radionuclides, notably of tritiated thymidine (3HTdR), but also of DF32P, 59Fe, 51Cr or 35S. These studies lead to the conclusion that the daily turnover in the actively renewing cell system amounts to
490×10^9 cells in the hematopoietic renewal system [BNID 113413], 0.7×10^9 cells in the skin and 56×10^9 cells in the mucosa of the gastrointestinal tract [primary source]. " |
