Are simple squamous epithelial cells and endothelial cells the same thing, or are they different ?
The cells are v similar [almost identical tho vary in different organs/tissues]; Greek epi = on top; endo = inside therefore e.g. endothelium of blood vessels = single layer of squamous [cornflake-shaped] cells called endothelial as they are on inside of vessel; epithelium of cornea [in eye] called Bowman's layer v similar tho not "simple" as 4-5 layers of cells NOT one WHEREAS endothelium of cornea {Descemet's membrane] v similar but one layer [so simple squamous].

Hope this helps clarify matters.

Be safe!
