摘要

背景:以前的研究表明,青鳉的咽齿是独立于视黄酸(RA)信号诱导的,这与斑马鱼(Danio rerio)不同。在斑马鱼中,咽齿的形成取决于咽齿形成部位前方的胚胎内胚层袋与邻近的外胚层裂隙之间适当的物理接触,这是一个依赖于视黄酸的过程。在这里,我们验证了一个假设,即胚胎青鳉的咽齿形成与斑马鱼一样,都需要适当的咽袋-咽裂接触。在严格控制时间的实验中,我们使用 4-[二乙基氨基]苯甲醛(DEAB)药理学抑制 RA 的产生,从而抑制咽袋-咽裂接触,并使用高分辨率成像对这些实验进行分析:结果:青鳉的咽齿只有在相应的前袋到达外胚层时才会出现(即建立了物理上的前袋-后袋接触),这与斑马鱼的情况类似。即使在正常口腔牙齿出现前约 4 天开始治疗,口腔牙齿也会出现:结论:斑马鱼和青鳉的咽齿形成对 RA 的依赖性并无不同。我们认为,青鳉的口腔牙齿和咽部牙齿对 DEAB 的不同反应可能是由于这两个区域参与牙齿形成的上皮细胞起源于不同的胚层。

Differential retinoic acid sensitivity of oral and pharyngeal teeth in medaka (Oryzias latipes) supports the importance of pouch–cleft contacts in pharyngeal tooth initiation

Background

Previous studies have claimed that pharyngeal teeth in medaka (Oryzias latipes) are induced independent of retinoic acid (RA) signaling, unlike in zebrafish (Danio rerio). In zebrafish, pharyngeal tooth formation depends on a proper physical contact between the embryonic endodermal pouch anterior to the site of tooth formation, and the adjacent ectodermal cleft, an RA-dependent process. Here, we test the hypothesis that a proper pouch–cleft contact is required for pharyngeal tooth formation in embryonic medaka, as it is in zebrafish. We used 4-[diethylamino]benzaldehyde (DEAB) to pharmacologically inhibit RA production, and thus pouch–cleft contacts, in experiments strictly controlled in time, and analyzed these using high-resolution imaging.

Results

Pharyngeal teeth in medaka were present only when the corresponding anterior pouch had reached the ectoderm (i.e., a physical pouch–cleft contact established), similar to the situation in zebrafish. Oral teeth were present even when the treatment started approximately 4 days before normal oral tooth appearance.

Conclusions

RA dependency for pharyngeal tooth formation is not different between zebrafish and medaka. We propose that the differential response to DEAB of oral versus pharyngeal teeth in medaka could be ascribed to the distinct germ layer origin of the epithelia involved in tooth formation in these two regions.
