单细胞测序技术(single-cell-sequencing)-综述(一)
单细胞生物学最近几年是非常热门的研究方向。在这一领域中,最前沿的则是单细胞测序技术。传统测序方法一次处理成千上万个细胞,得到的变异水平也是成千上万个细胞的平均后水平。但是,就如同世界上没有完全相同的两片树叶一样,没有两个细胞是完全相同的。所以,单细胞测序对于研究单个细胞就显得至关重要。单细胞测序可以

如何从单细胞水平探寻金属元素的药理学意义?
细胞是生命结构和生命活动的基本单位,基于单细胞的研究是生命研究的基础。单细胞分析可获得细胞在微环境中准确的个体信息,大量细胞个体呈现的差异性信息对于研究细胞的信号传导、生理病理和重大疾病的早期诊断具有十分重要的意义。 传统的细胞内金属含量的分析方法通常是:将细胞进行消解,然后通过原子吸收光谱(AAS
