我们详细介绍了一种研究和量化果蝇生殖系干细胞(GSCs)不对称细胞分裂(ACD)过程中染色质特征的分步方案。我们描述了使用双色组蛋白来研究新旧组蛋白的遗传。我们详细介绍了姐妹染色单体凝聚动力学和核小体密度变化的成像和分析步骤。此外,该方案还可以应用于干细胞的鉴定,而在完整的组织中鉴定干细胞可能具有挑战性。有关本议定书的使用和执行的完整细节,请参阅、和。双色组蛋白的产生以研究新旧组蛋白的遗传模式在干细胞分裂过程中染色单体凝聚的动力学和核小体密度详细描述了果蝇,但可以应用于其他生物来识别干细胞出版商的注释:进行任何实验方案都需要遵守当地实验室安全和伦理的机构指南。我们详细介绍了一种研究和量化果蝇生殖系干细胞(GSCs)不对称细胞分裂(ACD)过程中染色质特征的分步方案。我们描述了使用双色组蛋白来研究新旧组蛋白的遗传。我们详细介绍了姐妹染色单体凝聚动力学和核小体密度变化的成像和分析步骤。此外,该方案还可以应用于干细胞的鉴定,而在完整的组织中鉴定干细胞可能具有挑战性。
We detail a stepwise protocol for the investigation and quantification of chromatin features during asymmetric cell division (ACD) of Drosophila germline stem cells (GSCs). We describe the use of a dual-color histone to study the inheritance of new and old histones. We detail steps for imaging and analysis of sister chromatid condensation dynamics and nucleosome density changes. In addition, this protocol could be applied to identify stem cells, which can be challenging to identify in intact tissues. For complete details on the use and execution of this protocol, please refer to, and. Generation of dual-color histone to study inheritance pattern of old and new histones Dynamics of chromatids condensation and nucleosome density during stem cell division Detailed for Drosophila, but can be applied to other organisms to identify stem cell Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
