Fig. 9. Darkfield photomicrographs illustrating the localization of
TRH precursor and TRH receptor mRNAs in the pituitary of whiteadapted
Xenopus laevis. A: A moderate density of proTRH mRNA was
observed in the distal lobe (pd), but no hybridization signal was seen
in the intermediate lobe (pi). B: xTRHR1 mRNA was not present in
the distal lobe or in the intermediate lobe of the pituitary. C: Moderate
expression of xTRHR2 mRNA was seen in the distal lobe but not
in the intermediate lobe. D: xTRHR3 mRNA was virtually absent in
the distal lobe, although a strong hybridization signal was observed in
the intermediate lobe. Scale bar 20 um. |
