A multicellular organism is orchestrated by cell growth, death, differentiation, and communication at the single-cell level. To understand various crucial biological phenomena, we should massively perturb and measure transcriptomes and epigenomes at the single-cell level.
Our team will develop novel methods of comprehensive analysis and perturbation of transcriptome and epigenome at the single-cell level, in particular, by applying massively parallel DNA sequencing, genome editing, microfluidics, and machine learning. We focus on the development of methods for quantifying and controlling cell function, fate, and cell-cell communication at the single-cell level.
We have already reported novel single-cell RNA-sequencing methods, such as Quartz-Seq and RamDA-seq,which are highly reproducible and sensitive methods of quantifying single-cell transcriptome. Our team will not only develop new techniques but also collaborate with various life scientists within and outside of RIKEN using our new sequencing technologies.
With these techniques, our team seeks to promote the social well-being by contributing insights into how humans can achieve health and longevity.
Research Theme
- Development of novel single-cell omics techniques
- Collaboration with various biologists to apply novel single-cell omics technologies
