Epithelial and Endothelial Cells- How Do They Differ?

While discussing epithelial and endothelial cells, it is not easy to distinguish them but researchers have come up with some distinct features.

The endothelial cells and epithelial cells are derived from the epithelium, but they have differences in position, structure, and function.
