Fig. 4. TIA-1, TIAR, FBP1, and FBP2 are co-expressed during Xenopus
embryogenesis. (A) TIA-1, TIAR, FBP1, and FBP2 temporal expression
patterns were analyzed by RT-PCR. The embryogenesis stages studied are
indicated above each lane. The negative control corresponds to PCR
which has been made without template. Histone H4 was used as internal
control. (B) TIA-1, TIAR, FBP1, and FBP2 spatial expressions were
performed by whole-mount in situ hybridizations.
