Analysis of kidney development and disease models at a single-cell level

1, Establishment of a kidney disease model with human iPS cell-derived organoids
Chronic kidney disease (CKD) affects approximately 13 million people in Japan, which increases the risk of cardiovascular disease, end-stage renal disease, and mortality. On the other hand, there is no effective treatment.
Over the past decade, significant advances have been made in understanding the pathophysiology of CKD, mainly through the study of rodent models. However, the problem with rodent models is that they do not adequately recapitulate the morphological and genetic characteristics of human kidney diseases. Therefore, we would like to understand the pathogenesis of kidney disease by using human iPS cell-derived organoids to recapitulate human kidney disease and further analyze it at a single-cell level.

2. Elucidate the mechanism of the DoHAD theory
Low birth weight infants are more likely to develop lifestyle-related diseases such as CKD in adulthood. The phenomenon that the onset of lifestyle-related diseases is influenced by the intrauterine environment are called the DoHAD (Developmental Origins of Health and Disease) theory. We try to elucidate the DoHAD theory using PIC (Photo Isolation Chemistry)-RNAseq, a technique that can detect gene expression at the single-cell level.
