Palatogenesis was studied in the ferret (Mustela putorius) from day 27 to day 29 of gestation. At day 27 the primary palate is present as a flattened shield area, and the two secondary palatal shelves are directed at 45 degrees to the horizontal plane, passing downward on the lateral sides of the tongue, which occupies the space between them. By day 28 the primary palate is bulging convexly in the oral cavity, and the secondary palatal shelves have elevated and are in contact in the midline. Finally, at day 29 the primary palate and nasal septum are in contact with the two secondary palatal shelves. During fusion of the secondary palatal shelves, no structures (leading edges or filopedia) associated with cell movement were apparent. It is suggested there are two stages of secondary palate formation in the ferret; an initial contacting of the secondary palatal shelves with the production of cell debris, and further midline movement of the shelves and cell migration out of the epithelial seam.
在雪貂（鼬属）妊娠期的第27天至第29天对腭形成过程进行了研究。在第27天，原发腭表现为一个扁平的盾形区域，两个继发腭板与水平面呈45度角，向下延伸至占据它们之间空间的舌的两侧。到第28天，原发腭在口腔中呈凸出状隆起，继发腭板已抬高并在中线处接触。最后，在第29天，原发腭和鼻中隔与两个继发腭板接触。在继发腭板融合过程中，未观察到与细胞运动相关的结构（前缘或丝状伪足）。有人提出雪貂继发腭形成有两个阶段：继发腭板最初接触并产生细胞碎片，以及继发腭板进一步向中线移动和细胞从上皮缝中迁移出来。
