The role of basal immunoglobulin signaling in immature B cell development

This series represent several subgroups of experiments designed to investigate the role of basal immunoglobulin signaling in immature B cell development. The first subgroup of arrays (Ctrl Mhi, Cre Mhi, Cre Mlo) was done to identify the changes in gene expression in immature B cells as a consequence of inducible deletion of surface IgM expression via Cre-LoxP mediated excision of Ig heavy chain. The second subgroup of arrays (GFPneg, GFPpos, FxE Ctrl, FxE HA) was done to identify the changes in gene expression in immature B cells as a consequence of blockade of tyrosine kinase signaling with herbimycin A treatment. The third subgroup of arrays (FxD, FxE, B6 Mneg, HEL Mhi) was done to establish gene expression profiles of immature B, pre B and pro B cells as reference platforms for the other two subgroups.
