| Fig. 2. In situ hybridisation analysis of XFmi expression in whole embryos. (A) Sagittal section through an early gastrula (stage 10+) embryo. Faint expression of XFmi can be seen in the zone of internal involution just above the dorsal blastopore groove, and also in the ectodermal cells closer to the animal pole (the vegetal pole of the embryo is at the bottom, the animal pole at the top). (B) Dorsal view of the same stage embryo (10+). XFmi expression begins at a defined border above the dorsal blastopore lip (marked by the two lines), corresponding to the involuted cells. (C) Dorsal view of two early neurula (stage 13) embryos, the posterior end (marked by yolk plug; arrow heads) is on the right. No expression is detectable at this stage. (D) Lateral view of a mid neurula (stage 17) embryo, dorsal side uppermost. A faint staining is apparent at the anterior end of the embryo. (E) Lateral view of an early tail bud (stage 22) embryo, anterior to left. (F) Lateral view of a tail bud (stage 26) embryo, anterior to left. (G) Enlargement of the head of the embryo shown in (E). (H) Dorsal - anterior view of the embryo shown in (F), with the anterior-most end upwards. The anterior limit of XFmi expression is indicated by the two lines. A group of cells scattered around the midline, and anterior to this line, also express XFmi and are indicated by *. (I) Section through the embryo shown in (F) across indicated plane (�I�). The dorsal side is at the top. (J) Section through the embryo shown in (F) across the indicated plane (�J�). The dorsal side is at the top.
