List of distinct cell types in the adult human body

There are about 210 distinct human cell type
Cell type
A cell type is a distinct morphological or functional form of cell. When a cell switches state from one cell type to another, it undergoes cellular differentiation. A list of distinct cell types in the adult human body may include several hundred distinct types.-References:...

s,. There are between 50 and 75 trillion cells in the human body.

Cell types can be classified by their tissue of origin. However, it is possible for some cells to have their behavior induced by surrounding tissue.
