Question: what type of cells have you looked at

Paul Laurance-Young answered on 9 Nov 2019:

All of them! Literally all of them over the years: Blood cells, fat cells, brain cells, muscle cells, bone cells, cells that produce collagen, cells that produce mucus, cells with tiny cilia on the end waving out the rubbish in your lungs, egg cells, sperm cells, eye cells, skin cells….
there are thousands of types of cells to look at.
