Project description:Human iPSC-derived kidney organoids used for genome-wide CRISPR screening were profiled using scRNA-seq to characterize the maturation state at day 21, 28 and 35. Unsupervised clustering attributed cell types to segmented epithelium, podocytes and stroma and revealed stable cell type identity over time with a fibrotic signature in the stroma.

Project description:Analysis of gene expression changes in differentiated human podocytes treated with the serum from patients with (DKD+) or without (DKD-) diabetic kidney disease when compared to normal subjects (C). The hypothesis is that the three groups can be distinghed by their differential gene expression pattern. The results obtained revealed important information regarding differences in gene expression in human podocytes treated with the serum from patients with (DKD+) or without (DKD-) diabetic kidney disease when compared to normal subjects (C). Human podocytes were contacted with the serum from patients with diabetes and kidney disease (DKD+) or without kidney disease (DKD-) and compared to normal human podocytes contacted with serum from patients without diabetes (C).

Project description:The transcriptome is the complete set of all RNA transcripts produced by the genome in a cell and reflects the genes that are being actively expressed. Transcriptome analysis is essential for understanding the genetic mechanism controlling the phenotype of a cell. Using DNA microarray technique we examined transcriptomes of 2,000 individually collected inner (IHCs) and outer hair cells (OHCs), two types of auditory sensory cells critical for hearing. Among approximately 16,645 and 17,711 transcripts considered to be expressed, 1,296 and 256 genes showed significant differential expression in IHCs and OHCs, respectively. The top ten differentially expressed genes include Slc17a8, Dnajc5b, Slc1a3, Atp2a3, Osbpl6, Slc7a14, Bcl2, Bin1, Prkd1, Map4k4 in IHCs, and Slc26a5, C1ql1, Strc, Dnm3, Plbd1, Lbh, Olfm1, Plce1, Tectb, Ankrd22 in OHCs. Many unknown sequences and non-coding RNAs were also expressed in hair cells. The differentially expressed genes underlie the genetic mechanism for unique functions of IHCs and OHCs. The total RNA was extracted from the collected pools of single outer hair cell (OHC) and inner hair cell (IHC). Their whole-genome transcriptome expression was detected using GeneChip microarray analysis. The analysis and comparison between OHC and IHC allow us to determine what genes are expressed and what genes are uniquely or differential expressed in each population.

Project description:A critical event during kidney organogenesis is the differentiation of podocytes, specialized epithelial cells that filter blood plasma to form urine. Podocytes derived from human pluripotent stem cells (hPSC-podocytes) have recently been generated in nephron-like kidney organoids, but the developmental stage of these cells and their capacity to reveal disease mechanisms remains unclear. Here, we show that hPSC-podocytes phenocopy mammalian podocytes at the capillary loop stage (CLS), recapitulating key features of ultrastructure, gene expression, and mutant phenotype. hPSC-podocytes in vitro progressively establish junction-rich basal membranes (nephrin+ podocin+ ZO-1+) and microvillus-rich apical membranes (podocalyxin+), similar to CLS podocytes in vivo. Ultrastructural, biophysical, and transcriptomic analysis of podocalyxin-knockout hPSCs and derived podocytes, generated using CRISPR/Cas9, reveals defects in the assembly of microvilli and lateral spaces between developing podocytes, resulting in failed junctional migration. These defects are phenocopied in CLS glomeruli of podocalyxin-deficient mice, which cannot produce urine, thereby demonstrating that podocalyxin has a conserved and essential role in mammalian podocyte maturation. Defining the maturity of hPSC-podocytes and their capacity to reveal and recapitulate pathophysiological mechanisms establishes a powerful framework for studying human kidney disease and regeneration.

Project description:Like many cell types, the mechanisms and pathways underlying healthy aged-related changes to podocytes are not fully understood. Candidate pathways include oxidative stress, epigenetic changes, senescence, sirtuins, reduced autophagy and increased apoptosis, although detailed mechanisms underlying each pathway is not well defined. While detailed gene analysis has been undertaken on whole portions of the aging kidney, transcriptomic changes specific to podocytes in the aged kidney are not known. To address this, we used an inducible podocyte specific reporter mouse in which a cohort of podocytes are permanently labeled over the life time of the animal. RNA-seq was then used to measure transcriptional changes in genes in labeled podocytes in mice with advanced age, compared to podocytes from a cohort of young reporter mice.

Project description:To further understand the biological properties of hair cells of the mammalian cochlea, we examined the transcriptome of adult inner and outer hair cells. Morphologically distinct inner and outer hair cells were isolated from the organ of Corti from adult CBA/J mice. One thousand inner and outer hair cells were separately collected for each biological replicate, using the suction pipette technique. RNA sequencing of two biological replicates of IHCs and three biological replicates of OHCs, each with two technical repeats, was performed. The resulting sequenced reads were mapped. Comparisons between inner and outer hair cells allow identification of enriched genes, as well as differentially expressed genes that result in cellular specialization. Our dataset provides an extensive resource for understanding the molecular mechanisms underlying morphology, function, and pathology of adult mouse inner and outer hair cells.
