How many different types of cells are in the human body?

Many. As the cells descend from the fertilized zygote there are changes to which genes are even able to be expressed by altered proportions of transcription factors along with methylation of selected chromosomal regions. The distinction into 'types' is fairly arbitrary. Two cells of the same 'type' can be quite different in patterns of expressed genes. but for your convenience here is the link which might prove helpful. http://en.wikipedia.org/wiki/List_of_distinct_cell_types_in_the_adult_human_body Jun 12 07, 1:45 PM
