Fig. 2. Expression ofZfp488 coincides with that of differentiated
oligodendrocyte markers Mbp and Plp1/DM20 in the embryonic
spinal cord. In situ hybridization on transverse spinal cord sections from
E12.5 (A-C), E14.5 (D-F) and E18.5 (G-I) with probes to
murine Zfp488, Pdgfra, Mbp and Plp1/DM20.
(A-C) At E12.5, Pdgfra is expressed in the ventral spinal cord
(arrow) but Zfp488 and Mbp are not. (D-F) Expression of
Zfp488, Mbp and Plp1/DM20 is initially detected at
E14.5 in the ventral ventricular domain (D-F, red arrows) and Zfp488
is absent in the dorsal root ganglia (blue arrows). (G-I) At E18.5, expression
of Zfp488, Mbp and Plp1/DM20 occurs in a similar
distribution of cells in the ventral lateral white matter of the spinal cord
(arrows).
