Light micrograph of cervix revealing carcinoma
{"Image ImageDescription": "Light micrograph of a biopsy section through the human cervix revealing carcinoma-in-situ (severe dysplasia, CIN 3). The cervix is lined by a stratified squamous epithelium. Normally, all cell division is confined to the basal epithelial layer (centre of image). As a cell matures & rises up the layers, its cytoplasm expands & nucleus shrinks in size - a normal superficial cell is flat, with a small nucleus & a large cytoplasm. In carcinoma-in-situ the gradual stratification in cell maturation seen in normal epithelium is absent: dysplastic (abnormal) cells extend throughout the entire epithelium. The basement membrane remains defined & intact.", "Image XResolution": "72", "Image YResolution": "72", "Image ResolutionUnit": "Pixels/Inch", "Image YCbCrPositioning": "Centered", "Image Copyright": "Science Photo Library"}
