[Abstract]  In this protocol, we provide an experimental procedure that perform time-lapse observation of intra-cellular structures such as chromosomes, cytoskeletons and cell organelles during meiotic cell divisions in Drosophila males. As primary spermatocyte is the largest dividing diploid cell in Drosophila, which is equivalent in size to mammalian cultured cells, one can observe dynamics of cellular components during division of the model cells more precisely. Using this protocol, we have showed that a microtubule-associated protein plays an essential role in microtubule dynamics and initiation of cleavage furrowing through interaction between microtubules and actomyosin filaments. We have also reported that nuclear membrane components are required for a formation and/or ... [摘要]  在这个协议中,我们提供了一个实验程序,在果蝇男性的减数分裂细胞分裂期间,进行细胞内结构如染色体,细胞骨架和细胞器的延时观察。由于主要精母细胞是果蝇中最大的分裂二倍体细胞,其大小与哺乳动物培养细胞相当,可以更准确地观察模型细胞分裂期间细胞组分的动力学。使用该方案,我们已经表明,微管相关蛋白在微管动力学中起重要作用,并通过微管和肌动球蛋白丝之间的相互作用开始裂解沟槽。我们还报道说,需要核膜组分来形成和/或维持在果蝇细胞中细胞分裂所必需的主轴包络。

在果蝇中,也可以在标准培养条件下良好培养的良好培养细胞系。然而,它们的单元尺寸,特别是细胞质体积,比哺乳动物细胞的小得多。这在细胞分裂过程中损害了细胞成分的检查。精母细胞,在另一方面,实现第一次减数分裂开始之前不同的细胞生长。主要精母细胞是出现在果蝇发育中的增殖细胞中最大的二倍体细胞。因此,可以使用光学显微镜容易地细分观察分裂细胞中的细胞结构。在果蝇黑腹果蝇中,提供了先进和复杂的遗传技术(Ashburner等人,2004)。染色体分离和细胞分裂中的减数分裂缺陷出现在完成2< 减数分裂后精子细胞的细胞组织中。通过观察这种早期精子细胞,人们可以很容易地发现甚至微小的减数分裂异常(2012); 2012年; ...

[Abstract]  Regeneration of fish fins and urodele limbs occurs via formation of the blastema, which is a mass of mesenchymal cells formed at the amputated site and is essential for regeneration. The blastema transplantation, a novel technique developed in our previous studies (Shibata et al., 2016; Yoshinari et al., 2012) is a useful approach for tracking and manipulating the blastema cells during fish fin regeneration. [摘要]  鱼鳍和尿le肢的再生通过形成大气泡,其是在截肢位点处形成的质量的间充质细胞并且对于再生是必需的。胚胎移植是我们以前研究(Shibata等人,2016; Yoshinari等人,2012)开发的一种新技术,是一种有用的方法,用于跟踪和操纵鱼翅再生期间的blastema细胞。

背景在诸如鱼,两栖动物和哺乳动物之类的动物模型的早期胚胎阶段常规进行细胞移植研究,但将移植细胞靶向特定组织是困难的。在我们的研究中开发的Blastema移植是将间充质供体细胞引入宿主翅片射线的有效方法。它使我们能够在鱼翅再生期间跟踪细胞命运和/或操纵细胞信号,如成纤维细胞生长因子(Fgf)。实际上,在我们最近出版的作品中,我们将携带hsp701:显性负性fgf受体和β-肌动蛋白:dsRed2转基因的blastema细胞移植到野生型类型blastema区域并且在鳍状线间充质细胞的子集(Shibata等人,2016)中马齿抑制Fgf信号传导。该方法适用于分析其他细胞信号和通过活细胞成像跟踪细胞命运。

[Abstract]  Leptolyngbya boryana (L. boryana) (formerly Plectonema boryanum) is a versatile, filamentous cyanobacterium that has the ability to fix nitrogen under microoxic conditions and to grow heterotrophically with glucose in the dark, providing an excellent system to investigate photosynthesis, nitrogen fixation, and their regulatory mechanisms. While L. boryana is not naturally transformable different from the unicellular cyanobacterium Synechocystis sp. PCC 6803, it can be transformed by electroporation. Here we describe the transformation of L. boryana by electroporation to isolate mutants in which a targeted gene is disrupted. [摘要]   Leptolyngbya boryana ( L。boryana )(以前称为Plectonema boryanum)是一种多用途的丝状蓝细菌,具有在微氧条件下固氮的能力, 在黑暗中与葡萄糖异养生长,提供了研究光合作用,固氮和它们的调节机制的优良系统。 而 L。 boryana 不是天然可转化的,不同于单细胞蓝细菌集胞藻。 PCC 6803,它可以通过电穿孔转化。 这里我们描述了 L的变换。 boryana通过电穿孔分离其中靶基因被破坏的突变体。
