Large image: Hematoxylin and eosin stained tissue culture of the
mouse P19 embryonal carcinoma cell line induced to neuronal differentiation
by retinoic acid. A gene that we are studying, DBCCR1, appears to
be important in the process.
Top
right: Three color fluorescence microscopy in which the cellular
distribution of two proteins (red and green colors) can be visualized
together with the DNA (blue color).
Bottom
right: Fluorescence in situ hybridization. Three copies of chromosome
9 (green spots) can be seen in this nucleus. The DNA is stained
with a fluorescent blue dye.
