Because of the significance of zebrafish Dapper2 in mesoderm induction, the mouse dapper2 was cloned following its homolog. The study of its spatial and temporal expression pattern showed that it expressed specifically in otic vesicle, somite,gut and roof plate of mouse embryos.

鉴于Dapper2对于胚胎中胚层发育的重要性，本文首先克隆出小鼠Dapper2基因，并研究其时空表达谱，发现它在体节形成期后在体节、耳泡、神经顶板、肠等组织中特异性表达。

MethodsNeural tubes isolated from the region between midotic placode and third somite of mouse embryo at ED 8.5d were cultured in DMEM/F12 serum-free medium containing basic fibroblast growth factor and epidermal growth factor. The cell cycle of CNCCs was analyzed with flow cytometry, the proliferation capability was determined by MTT method, AP-2α expression was detected by immunocytochemistry as a biological marker of cardiac neural crest cells. The features of migration, multi-directional differentiation were observed as well.

材料与方法成年2月龄C57／BL6小鼠交配，取ED8.5d小鼠胚胎枕中部至第3体节神经管，应用包含碱性纤维生长因子和表皮细胞生长因子的无血清培养基培养，利用MTT法检测细胞增殖能力，利用流式细胞仪检测细胞周期，采用转录激活因子2α(AP-2α，Activator protein-2α)作为其生物学标记物，观察其增殖状况、细胞周期、迁移、分化等生物学特性。

In 10.5 day mouse embryo, by the induction of notochord, mesenchymal cells of ventromedial somite differentiate into sclerotome, cells migrate towards notochord, forming perinotochord tube around notochord, the cartilage is till invisible, alcian dying is faintly positive.

椎体区域发生骨化后（E16.5），阿利辛兰染色呈阴性，茜素红染色呈阳性，仅有Ihh在椎体边缘有表达，无PTHrP表达；在椎间盘区域，仍然保持阿利辛兰染色阳性，仅有PTHrP的表达，无Ihh表达。

To address this issue, we microinjected Morpholino Oligonucleotides, which acts as a specific translational inhibitor, into 1-cell stage zebrafish embyos to knockdown the expression of FoxD5. Results showed that the newly forming somites of the FoxD5-MO-injected embryos were malformed both in the stage when the somitogenesis was completed (24-hpf) and in the stage when the somitogenesis was in progress (14-hpf).

在本篇研究中，为了了解FoxD5在体节生成时的功能，利用专一抑制基因转译之Morpholino Oligonucletides对1-cell时期之斑马鱼胚胎进行显微注射以抑制FoxD5的转译，并在体节发育已完成之24 hpf时、及体节仍在形成之14 hpf (约12-somite stage)时分别观察FoxD5-MO注射个体(FoxD5 morphants)，发现新生成之体节处有产生体节发育畸形的现象。
