脉络丛(ChP)是血脑屏障(BBB)的组成部分,产生脑脊液(CSF),因此在(i)保护和滋养大脑以及(ii)在神经发育期间协调神经元迁移中发挥作用。到目前为止,由于技术问题,尚未在活体脊椎动物中分析ChP的发育。我们分析了第四脑室ChP的斑马鱼在GFP标记的增强子陷阱转基因系SqET 33-E20(网关)的形成,在体内成像,组织学和突变体分析的组合。这一过程包括脉络膜组织(TC)的形成,菱形唇细胞的募集,最后,TC的聚结导致ChP的形成。在Notch缺陷型mib突变体中,该过程的第一阶段受到GFP过早表达、TC细胞募集缺陷和ChP模式异常的影响。在刺猬缺陷型smu突变体中,ChP形态发生的第二阶段缺乏细胞募集,TC细胞发生凋亡。这项研究是第一个证明在体内形成的ChP揭示了Notch和刺猬信号通路在这一过程的不同发育阶段的作用。
The choroid plexus (ChP), a component of the blood-brain barrier (BBB), produces the cerebrospinal fluid (CSF) and as a result plays a role in (i) protecting and nurturing the brain as well as (ii) in coordinating neuronal migration during neurodevelopment. Until now ChP development was not analyzed in living vertebrates due to technical problems. We have analyzed the formation of the fourth ventricle ChP of zebrafish in the GFP-tagged enhancer trap transgenic line SqET33-E20 (Gateways) by a combination of in vivo imaging, histology and mutant analysis. This process includes the formation of the tela choroidea (TC), the recruitment of cells from rhombic lips and, finally, the coalescence of TC resulting in formation of ChP. In Notch-deficient mib mutants the first phase of this process is affected with premature GFP expression, deficient cell recruitment into TC and abnormal patterning of ChP. In Hedgehog-deficient smu mutants the second phase of the ChP morphogenesis lacks cell recruitment and TC cells undergo apoptosis. This study is the first to demonstrate the formation of ChP in vivo revealing a role of Notch and Hedgehog signalling pathways during different developmental phases of this process.
