The paper develops vascular organoids that integrate into retinal organoids, revealing diabetic retinopathy-like gene expression patterns in endothelial-like cells.

This study transplants human iPSC-derived cardiomyocyte aggregates into non-human primates with myocardial infarction, showing efficient engraftment and functional recovery with lower cell doses than previous single-cell approaches.

This study introduces a biallelic inducible Caspase9 suicide gene system in hiPSCs to prevent drug-resistant escapees, showing no escapees in biallelic cells versus rare escapees in monoallelic cells.
