Project description:Single-cell RNA-seq of engineered healthy human kidney organoids. These data are part of a larger investigation (data not provided here) showing that SARS-CoV-2 can directly infect engineered human blood vessel organoids and human kidney organoids which can be inhibited by human recombinant soluble ACE2 (hrsACE2), demonstrating that hrsACE2 can significantly block early stages of SARS-CoV-2 infections.
Project description:Here we developed a method to incorporate a genetically engineered endothelial niche into an established protocol for generating human kidney organoids.
Project description:Safety issues of human iPSC-derived kidney organoids as a regenerative therapy need to be evaluated. Therefore, we studied the immunogenicity of human iPSC-derived kidney organoids. We subcutaneously implanted kidney organoids in immune-deficient IL2Ry-/-RAG2-/- mice for 1 month and hereafter performed adoptive transfer of healthy allogeneic human PBMC. We used single cell RNA sequencing (scRNA-seq) to analyze the diversity of kidney organoid cells and immune cell profiles. We investigated whether innate and adaptive immune cells invade kidney organoids, evoke an immune response, and influence the kidney organoid differentiation and functional capacity. Understanding the immunogenicity of kidney organoids will advance studies in the applicability of kidney organoids for regenerative medicine. Furthermore, it can serve as an in-vivo transplantation model to study solid organ transplantation.
Project description:To reveal the key pathways involved in kidney cystogenesis. We performed single nuclei gene expression and ATAC profiling using kidney organoids from ARPKD patients-iPSCs derived organoids.
