在这里,我们提出了一种方案,可以在受精后至少 1 到 7 天之间的任何阶段将具有高空间和时间分辨率的细胞移植到斑马鱼胚胎和幼虫中。
我们的实验室研究细胞连接在发育和再生过程中如何在神经系统中形成模式。我们通过使用细胞移植来研究环境信号如何影响神经行为,以解决当它们被放置在不同的遗传、空间或时间环境中时它们的行为如何变化。虽然移植在斑马鱼胚胎中很常见,但通常在囊胚和原肠阶段进行,此时细胞基本上未分化。
这对于生成遗传镶嵌很有价值,但它限制了该技术询问时空信号动力学如何影响这些阶段之后的发育的能力。在这里,我们提出了一种方案,允许在受精后至少 7 天内移植细胞,包括胚胎和幼虫中的分化神经元。我们可以移植具有高空间和时间分辨率的低至一个细胞,并使用遗传荧光标记来长期追踪宿主动物中移植的细胞。
