Unformatted text preview: 6. Cell differentiation “markers” These “markers’ refer to gene products (usually proteins) that are characteristic and unique to a specific cell type. (e.g., the ephrinB2 transmembrane protein found only in differentiated arterial ECs). EphrinB2 is not expressed in undifferentiated ECs or in venous endothelial cells. 7. Immunocyto (histo) chemistry A technique used to identify and locate cell-specific markers on cells or tissues by using a labeled antibody and a microscopic technique to visualize the label. 8. Scanning confocal fluorescence microscopy A microscopic technique used to visualize fluorescently labeled antibodies or other fluorescent molecules bound to cells or tissues. 9. “E” “E” refers to the age of embryos. For example, E15.5 refers to a mouse embryo that is 15.5 days old (has developed in utero for 15.5 days since conception). Mice have a gestation period of 21 – 22 days....
