单细胞测序是近十年来生命科学领域最重要的技术突破之一,该技术已经成为生命科学领域的底层技术,在发育、进化,人类疾病等领域全面应用,使得人们可以在单细胞分辨率研究生命的多组学图谱,理解生命起源和生老病死。
华大研究院过去在单细胞测序工具研发方向不断取得突破,目前在单细胞基因组/外显子组测序(Xu et al., Cell, 2012, Hou et al., Cell, 2012), 单细胞全长转录组 (Wu et al., GigaScience, 2015), 单细胞多组学(Liu et al., Nature Communications, 2019)等领域均处于世界领先地位。
当前单细胞测序技术在成本,通量等方向存在挑战,为了进一步实现单细胞组学全方位规模化应用,推动全球单细胞组学研究和临床应用。华大研究院自主研发了高通量的单细胞建库系统DNBelab C4, 该系统具有便携,低成本等方面具备显著优势,可以实现高通量单细胞转录组,表观组和多组学测序。目前该系统已经转化华大智造,于2019年10月正式对外发布。通过全球合作,该系统已经在发育,疾病,动植物演化,衰老,脑科学等领域实现全面应用。与此同时,结合华大自主研发的DNBSEQ高通量的测序系统以及自动化建库系统,华大目前在深圳,青岛,北京,欧洲等地已全面实现单细胞数据规模化生产。
