Movement of the Hoxb1 toward the center of the nucleus. The localization of Hoxb1 and Hoxb9 hybridization signals within erosion shells from the edge (shells 1 and 2) toward the center (shells 4 and 5) of the nucleus. Analysis was performed on MAA-fixed nuclei from undifferentiated ES cells (open bars) and from cells after 4 and 10 d of differentiation (hatched and filled bars, respectively). n = 50 cells.
