Fig. 3. Spliced Tsix RNA is eliminated in the placenta. The absence
of the splicing products of Tsix was confirmed in the E13.5 placenta
carrying Tsix
SA in the same
manner as in ES cells shown in Fig. 2A and
B. It is evident that the splicing products are not detected in
the placenta of Tsix
SA/+ and
Tsix
SA/Y embryos despite the
presence of the antisense transcription.
