Description: Notch signaling has been shown to play important roles during hematopoiesis. However, a clear understanding of the expression pattern of Notch family genes is still to be determined. Although expression of Notch receptors and ligands has been detected in a very broad range of tissues, the findings were often contradictory. I have addressed this question by assessing beta-galactosidase (beta-gal) expression in several reporter strains of mice: Dll1+/lacZ , Notch2+/lacZ, Notch3+/lacZ, and MFng lacZ/lacZ. I detected lacZ expression by flow cytometry using di-beta-D-galactopyranoside (FDG), a fluorogenic beta-gal substrate, to stain viable cells based on their lacZ expression. Using this method I was able to detect beta-gal in subsets of lymphoid and myeloid cells from Notch2+/lacZ, Notch3 +/lacZ and MFnglacZ/lacZ mice. In particular, I detected high beta-gal expression in activated T and B cell from Notch2+/lacZ  mice, suggesting a role for Notch2 in T and B cells activation and/or proliferation.
