Rac1 and RhoA are expressed in developing hippocampus. A, Dark-field image of a coronally sectioned P8 rat hippocampus hybridized with an antisense S35-riboprobe against Rac1, showing distribution of Rac1 mRNA in the dentate gyrus and CA1 and CA3 pyramidal cell layers.B, Dark-field image of antisense riboprobe showing distribution of RhoA mRNA. C, Dark-field image of the Rac1 sense riboprobe showing background staining. D,Bright-field image of the same hippocampus shown in Cwith the CA1, CA3, and dentate gyrus (DG) labeled. Scale bar, 2 mm.
