RE: Science Lesson: DNA (Part 1)
Ron Sender, Shai Fuchs and Ron Milo state in their research:
For human cells we identify the dominant role of the hematopoietic lineage to the total count of body cells (≈90%), and revise past estimates to reach a total of 3.0·10^13 human cells in the 70 kg ″reference man″ with 2% uncertainty and 14% CV.
I was wondering whether you have the answer to my question: Does a 200 lb. human have say twice as many cells as a 100 lb. human or is it that the bigger individual's cells are bigger with a similar number of cells? Or both? I have not been able to find an answer to that question and I thought you may know.
BTW thanks, @justtryme90, I thoroughly enjoyed this article and am in the process of reviewing your series.
Larger bodies have more cells, heavier bodies (fatter bodies) have more and larger adipose cells. Exercise (weight lifting) increases the volume of muscle cells but generally does not generate additional cells. So I would say there is some combination of both, depending on what ways the two bodies differ.
