Image of the Month - February 2007
Loss of the retinoblastoma protein permits differentiated enteroendocrine cells to remain in the cell cycle and hyperproliferate.
Intestinal section from a mouse that was heterozygous for a conditional knockout mutation of the retinoblastoma gene was stained by immunofluorescence for the cell proliferation marker Ki-67 and the enteroendocrine marker serotonin. The merged image shows staining with anti-Ki67 in green, anti-serotonin in red and DAPI in blue.
