Pax3 and Pax7 are closely related transcription factors that are widely expressed in the developing nervous system and somites. In the CNS, both genes are expressed in the dorsal part of the neural tube during development. Pax3 and Pax7 are involved in the sonic hedgehog (Shh) signaling pathway and are inhibited by Shh overexpression. The present study(More)
OBJECTIVE Sonic hedgehog(SHH) is early expressed in the floor plate and notochord during the development of chicken embryo, which is required for the establishment of dorsal axis and the formation of spinal cord, but the mechanism of SHH affecting the patterns of spinal development is still unclear. METHODS In this study using in vivo electroporation(More)
In utero electroporation (IUE) is a simple and rapid approach to in vivo investigate exogenous gene function in mouse brain, and intensive studies using IUE have greatly contributed to analyze the characterization of specific steps during mouse brain development. Because the efficiency of IUE is highly dependent on the plasmid used and its concentration,(More)
Pax3 is a transcription factor that belongs to the paired box family. In the developing spinal cord it is expressed in the dorsal commissural neurons, which project ascending axons contralaterally to form proper spinal cord-brain circuitry. While it has been shown that Pax3 induces cell aggregation in vitro, little is known about the role of Pax3 in cell(More)
N-cadherin is a calcium-sensitive cell adhesion molecule that plays an important role in the formation of the neural circuit and the development of the nervous system. In the present study, we investigated the function of N-cadherin in cell–cell connection in vitro with HEK293T cells, and in commissural axon projections in the developing chicken spinal cord(More)
Niemann-Pick disease, type C1 (Npc1), is an atypical lysosomal storage disorder caused by autosomal recessive inheritance of mutations in Npc1 gene. In the Npc1 mutant mice (Npc1-/- ), the initial manifestation is enlarged spleen, concomitant with free cholesterol accumulation. Telocytes (TCs), a novel type of interstitial cell, exist in a variety of(More)
Few researchers have investigated the direction of commissural axon projections on the contralateral side of the vertebrate embryonic spinal cord, especially for comparison between its different regions. In this study, pCAGGS-GFP plasmid expression was limited to different regions of the chicken embryonic spinal cord (cervical, anterior limb, anterior(More)
Chicken embryos are used widely in the fields of developmental biology and neurobiology. The chicken embryo also serves as a model to analyze gene expression and function using in ovo electroporation. Plasmids may be injected into the spinal cord or tectum of the chicken central nervous system by microinjection for electroporation. Here, we developed a(More)
