Insights
四种染料在人类梅博米腺细胞中进行了细胞内脂质检测的测试. 油红O,苏丹III和LipidTOX绿色有效地识别了在分化过程中的脂质积累,与尼罗河红色不同.
科学领域:
- 细胞生物学 细胞生物学
- 眼睛表面研究 眼睛表面研究
- 脂质代谢 脂质代谢是什么
背景情况:
- 细胞内脂质积累对于梅博米腺上皮细胞分化至关重要.
- 需要准确的检测方法来研究人类梅博米腺上皮细胞 (IHMGECs) 中的脂质变化.
研究的目的:
- 为了比较四种常见染料 (Oil Red O,Sudan III,LipidTOX绿色,尼罗河红色) 在IHMGEC中检测细胞内脂质的疗效.
- 为了评估这些染料如何显示由Roxadustat诱导的脂质变化,一个差异化剂.
主要方法:
- 为了诱导分化,IHMGECs被培养并与Roxadustat或没有Roxadustat一起处理.
- 细胞使用Oil Red O,Sudan III,LipidTOX绿色或尼罗河红色进行染色.
- 使用显微镜和ImageJ软件量化了脂质囊泡的大小,数量,面积和染色强度.
主要成果:
- 油红O和苏丹III在接受Roxadustat治疗的细胞中增加了脂质囊泡的大小和面积,而油红O显示出比苏丹III更大的囊泡.
- LipidTOX绿色表示细胞内脂质强度增加,而尼罗河红色没有显示显著变化.
- 所有测试的染料都显示了脂质模式的差异,但油红O,苏丹III和LipidTOX绿色比尼罗河红更有效.
结论:
- 油红O,苏丹III和LipidTOX绿色适用于量化细胞内脂质积累,以区分IHMGECs.
- 尼罗河红色在检测Roxadustat诱导的脂质变化方面效率较低,在这种细胞模型中.
- 染料选择对IHMGECs中脂质动态的评估产生重大影响.

01:03Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

01:26Differential Staining Technique
Differential staining is an essential microbiological technique that exploits variations in cell wall structures to classify and identify microorganisms. It facilitates the distinction of bacteria, aiding in diagnostic and research applications. Two of the most widely used differential staining methods are Gram staining and acid-fast staining, both of which rely on the chemical and structural differences in bacterial cell walls.Gram Staining TechniqueGram staining differentiates bacteria by...
