Figure 2. mRNA expressions of clones H59 to J55 during various embryonic stages

The spatiotemporal expression of clones H59 through J55 is shown (see text and Table 1 for additional information regarding these clones). Clear expression can be seen in the developing lens in all cases. Also note that in some cases, expression is also observed in tissues beyond the lens. All specimens are oriented so that the anterior end is toward the left and the dorsum is oriented toward the top. H59: Stages 26, 32, and 37. H77: Stages 23, 30, and 35. H84: Stages 24, 31, and 35. H97: Stages 23, 31, and 34. H98: Stages 24, 31, and 35. H151: Stages 27, 31, and 35. H163: Stages 23, 32, and 35. H186: Stages 27, 33, and 34. J55: Stages 26, 32, and 34. In the images, "ov" refers to the otic vesicle, "pa" refers to the pharyngeal arches, "pd" refers to the pronephric duct, "pi" refers to the pineal, "pn" refers to the pronephros, and "so" refers to the somites. The scale bar represents 600 μm.
