We developed induction of pluripotency from pooled cells (iPPC) to efficiently reprogram many somatic cells into induced pluripotent stem cells (iPSCs). This scalable method allows for multiplexed analysis of in vitro phenotypes and reprogramming ability.
Area of Science:
- Stem cell biology
- Genomics
- Biotechnology
Background:
- Reprogramming somatic cells into induced pluripotent stem cells (iPSCs) is crucial for in vitro studies.
- Current methods lack high throughput and scalability for analyzing diverse cell populations.
Purpose of the Study:
- To develop a scalable and efficient method for reprogramming pooled somatic cells into iPSCs.
- To enable multiplexed analysis of individual reprogramming efficiencies and in vitro phenotypes.
Main Methods:
- Developed induction of pluripotency from pooled cells (iPPC) procedure.
- Utilized a deconvolution algorithm with pooled sequencing of single-nucleotide polymorphisms (SNPs) to determine individual donor proportions.
- Concurrently reprogrammed over one hundred donor lymphoblastoid cell lines (LCLs).
Main Results:
- iPPC demonstrated efficient, scalable, and reliable reprogramming of pooled LCLs into iPSCs.
- Accurate estimation of individual donor proportions in pooled iPSCs using SNP deconvolution.
- Consistent individual donor reprogramming ability across experiments, with potential influence from immunoglobulin precursor gene expression.
- Successfully differentiated pooled iPSCs into cerebral organoids.
Conclusions:
- iPPC provides a robust multiplex framework for generating pooled iPSC libraries.
- Facilitates large-scale investigation of in vitro phenotypes and donor-specific reprogramming efficiencies.
- Enables advanced downstream research applications using diverse iPSC collections.
