Summary

在这里,我们讨论了一种工作流程,用于准备、解剖、安装和成像来自黑 腹果蝇 第三龄幼虫的活外植体大脑,以观察生理条件下的细胞和亚细胞动力学。

Transcript

我们的研究重点是研究不对称细胞分裂或ACD对干细胞增殖和分化的影响。我们使用果蝇神经干细胞或神经母细胞作为模型来了解不对称细胞分裂对发育和神经发生的机制、法规和影响。人工智能的最新发展在图像量化和分析方面取得了重大进展,这大大推动了生命细胞成像领域的发展。

保持长期电影的采样质量是一项长期挑战。虽然观察样品 8 到 10 小时很有见地,但后勤限制,如样品的成像要求和可用的成像工具,使其变得困难。我们的实验方案通过在不影响样品质量的情况下展示长期成像来解决这个问题。

我们的技术可以很容易地被新来者采用和应用于该领域。通过一些时间和实践,人们可以制作短期和长期电影,这些电影有可能产生有见地和有意义的数据。
