How many consecutive cell divisions are required to form the adult human body from the single cell zygote?

An estimation of the number of cells in the human body
A current estimation of human total cell number calculated for a variety of organs and cell types is presented. These partial data correspond to a total number of 3.72 × 10^13 (37.2 Trillion) 1 The question is: what would be the approximate number of cell divisions required to reach that number (Ignoring the fact that different tissues may reach full differentiation at different times)? Between 50 and 70 billion cells die each day due to apoptosis in the average human adult. For an average child between the ages of 8 and 14, approximately 20 billion to 30 billion cells die a day. For every cell that dies a new one must be born, so there must be at least between 50 and 70 billion cell divisions to replenish these cells in an adult human (no net growth). Over the course of an average life, the estimated 37 trillion cells in our body will regenerate by dividing about 50 to 70 times
