Project description:Podocytes play an important filtration role in the kidney. We examined culture condition for efficient podocyte induction and established a method to selectively induce podocytes from human iPS cells. To understand how expression profiles of human iPS cell-derived podocytes were close to that in vivo, we isolated human adult podocytes for human adult kidney. Purified RNAs from human iPS cells, nephron progenitor cells, human immortalized podocyte cell line, human iPS cell-derived podocytes, and sorted human adult podocytes were analyzed by RNA-seq.

Project description:ATAC-seq samples from 2 species and 2 cell types were generated to study cis-regulatory element evolution. Briefly, previously generated urinary stem cell derived iPS-cells (Homo sapiens) of 2 human individuals and fibroblast derived cynomolgus macaque iPSCs (Macaca fascicularis) of 2 individuals (Geuder et al. 2021) were differentiated to neural progenitor cells via dual-SMAD inhibition as three-dimensional aggregation culture (Chambers et al. 2009; Ohnuki et al. 2014). The NPC lines were cultured in NPC proliferation medium and passaged 2 - 4 times until they were dissociated and subjected to ATAC-seq together with the respective iPSC clones. ATAC-seq libraries were generated using the Omni-ATAC protocol (Corces et al. 2017) with minor modifications.

Project description:ASoC variants are prevalent and cell type-specific ASoC variants were over-represented in intergenic regions and active enhancers. The collection includes ATAC-Seq and RNA-Seq data that were taken from human iPS cells and their derived neuronal cells (neural progenitor cells, cortical glutamatergic neurons, GABAergic neurons, and dopaminergic neurons).

Project description:In this study we have compared functional and molecular properties of highly purified murine induced pluripotent stem (iPS) cell- and embryonic stem (ES) cell-derived cardiomyocytes (CM). In order to obtain large amounts of purified CM, we have generated a transgenic murine iPS cell line, which expresses puromycin resistance protein N-acetyltransferase and EGFP under the control of the cardiomyocyte-specific α-myosin heavy chain promoter (alphaMHC-Puro-IRES-GFP, aPiG). We demonstrate that murine aPIG-iPS and aPIG-ES cells differentiate into spontaneously beating CM at comparable efficiencies. When selected with puromycin both cell types yielded more than 97% pure population of CMs. Both aPIG-iPS and aPIG-ES cell-derived CM express typical cardiac transcripts and structural proteins and possess similar sarcomeric organization. Action potential recordings revealed that iPS- and ES cell-derived CM respond to beta-adrenergic and muscarinic receptor modulation, express functional voltage-gated sodium, calcium and potassium channels and possess comparable current densities. Comparison of global gene expression profiles of CM generated from iPS and ES cells revealed that both cell types cluster close to each other but are highly distant to undifferentiated ES or iPS cells as well as unpurified iPS and ES cell-derived embryoid bodies (EB). Both iPS and ES cell-derived CMs express genes and functional categories typical for CM. They are enriched in genes involved in transcription and genes coding for structural proteins involved in cardiac muscle contraction and relaxation. They also express genes involved in heart and muscle developmental processes, ion export and ion binding processes and various metabolic processes for ATP synthesis. These CMs downregulate genes involved in immune response, cell cycle and cell division, thus demonstrating the CMs population is mitotically inactive. Most surface signaling pathways are also downregulated. Thus, a transgenic aPiG-iPS cell line can provide a robust supply of highly purified and functional CMs for future in vitro and in vivo studies. Seven different experimental groups were included into analysis: undifferentiated murine ES cells (1) and undifferentiated murine iPS cells (2), murine ES cell-derived embyroid bodies (3) and murine iPS cell-derived embryoid bodies at day 16 of differentiation (4), murine ES cell-derived cardiomyocytes (5) and murine iPS cell-derived cardiomyocytes (6) at day 16 of differentiation (they were generated by puromycin selection for 7 days prior to RNA isolation). Adult mouse tail tip fibroblasts (7) were used as a control for iPS cells. Total RNA samples were prepared from three independent biological replicates in groups 1-6. In group 7, single RNA probes were analyzed as three technical replicates.

Project description:The 22q11.2 deletion syndrome (22q11.2DS) is the most common copy number variant (CNV)-associated syndrome, leading to congenital and neuropsychiatric anomalies. Patient-derived, induced pluripotent stem cell (iPS) models have provided important insight into the mechanisms of phenotypic features of this condition. However, patient-derived iPSC models may harbor underlying genetic heterogeneity that can confound analysis of pathogenic CNV effects. Furthermore, the ~1.5 Mb “A-B” deletion at this locus is inherited at higher frequency than the more common ~2.7 Mb “A-D” deletion, but remains under-studied due to lack of relevant models. To address these issues, here we leveraged a CRISPR-based strategy in Cas9-expressing iPS cells to engineer novel isogenic models of the 22q11.2 “A-B” deletion. After in vitro differentiation to excitatory neurons, integrated transcriptomic and cell surface proteomics identified deletion-associated alterations in surface adhesion markers. Furthermore, implantation of iPS-derived neuronal progenitor cells into the cortex of neonatal mice found decreased proliferation and accelerated neuronal maturation within a relevant microenvironment. Taken together, our results suggest potential pathogenic mechanisms of the 22q11.2 “A-B” deletion in driving neuronal and neurodevelopmental phenotypes. We further propose that the isogenic models generated here will provide a unique resource to study this less-common variant of the 22q11.2 microdeletion syndrome.
