Spatial expression of Jak1 kinase during early embryogenesis. The developmental profile of Jak1 RNA was revealed by in situ hybridization, using digoxigenin-labeled antisense RNA probes. In agreement with results from RT–PCR quantitation, Jak1 kinase is present through the blastula stage of development and then rapidly disappears. The message is uniformly distributed among all blastomeres. The scale bar equals 0.5 mm.
