Gene Expression Study in E17.5 Mouse Embryos

In situ hybridizations of cryosections from E17.5 mouse embryos demonstrate the nearly identical expression patterns of Trip4 (A, C, and E) and of Ascc1 (B, D, and F) mRNA. At the lower thoracic level (A and B), the highest expression levels were seen in the spinal cord, dorsal root ganglia, paraspinal sympathetic ganglia, muscle, lung, and brown fat tissue. In the parasagittal sections, the highest expression levels were seen on the thyroid and submandibular salivary gland and the trigeminal ganglion. Abbreviations are as follows: B, brain; BFT, brown fat tissue; CB, cerebellum; DRG, dorsal root ganglion; GUT, gut; H, heart; KID, kidney; LIV, liver; LU, lung; PC, pancreas; SC, spinal cord; SM, skeletal muscle; SMG, submandibular salivary gland; ST, sympathetic tract; TG, trigeminal ganglion; TG, thyroid gland; TM; thymus; VC, vertebral column.
