Cheek cells. Computer-enhanced light micrograph of squamous epithelial cells from the human mouth. These flat,scale-like cells have small oval nuclei and granular cytoplasm. The epithelia are tissues that cover all body surfaces,cavities and tubes apart from the blood and lymph vessels. Epithelial cells form a protective layer within the mouth. Cells such as these may be taken for genetic tests like DNA (deoxyribonucleic acid) fingerprinting. Magnification: x200 at 5x7cm size | |
