Differentiation of human amniotic fluid kidney progenitor cells into podocytes and comparison with human conditionally immortalized podocytes

Project description:In this work, we isolated and characterized a novel cell population derived from human amniotic fluid cells (hAKPC-P), and we differentiated them into podocytes. We used microarrays to study global changes in gene expression before and after differentiation in hAKPC-P and human immortalized podocytes (hIPod, positive control) and performed a detailed comparison between the different populations hAKPC-P were isolated by FACS sorting from the total human amniotic fluid cell population and differentiated into podocytes using VRADD media. Morphological, phenotypical and functional analysis were performed to assess their differentiation. To confirm the results, cells were compared with human conditionally immortalized podocytes.

Gene expression in a conditionally immortalized mouse podocyte cell line

Project description:The specialized glomerular epithelial cell (podocyte) of the kidney is a complex cell that is often damaged in glomerular diseases. Study of this cell type is facilitated by an in vitro system of propagation of conditionally immortalized podocytes. Here, genes that are differentially expressed in this in vitro model of podocyte differentiation are evaluated. Conditionally immortalized undifferentiated mouse podocytes were cultured under permissive conditions at 33*C. Podocytes that were differentiated at the non-permissive conditions at 37*C were used for comparison.

Gene expression profiling of human iPS cell-derived podocytes and sorted human adult podocytes

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.

Characterizing human pluripotent stem cell derived kidney organoids by single-cell RNA sequencing of whole organoids and bulk RNA sequencing of organoid-derived podocytes for comparison with immortalized podocytes and in vivo podocytes

Project description:We performed single-cell sequencing to characterize the cell types that are present in human induced pluripotent stem cell derived (iPS) kidney organoids and their transcriptional profile. Furthermore, using bulk RNA sequencing we compared the transcriptional profile of kidney organoid derived podocytes from a wildtype iPS line, an iPS line with 2 mutations in podocin (NPHS2) which causes clinical manifestation of nephrotic syndrome and an iPS line with one of these mutations repaired which causes no clinical symptoms. For reference and comparison we took along human in vivo glomeruli and a human conditionally immortalized podocyte cell line.

Differentiated mouse podocytes (SVI)

Project description:Transcriptomes of differentiated cells of the conditionally immortalized mouse podocyte cell line SVI (Schiwek et al., Kidney Int. 66: 91-101, 2004) were determined as described in Kabgani et al. (PLoS One 7:e34907, 2012). The transcriptomes of the podocyte cell line were mapped on a protein-protein interaction network of the podocyte (PodNet). Together with other transcriptomes taken from GEO, we analyzed differential gene regulation and differential regulation of protein-protein interactions between cultured podocytes and differentiated in vivo podocytes. Three independent batches were used.

Mechanical stress enhances CD9 expression in cultured podocytes

Project description:Transcriptomes of differentiated cells of the conditionally immortalized mouse podocyte cell line SVI (Schiwek et al., Kidney Int. 66: 91-101, 2004) were determined as described in Warsow et al. (Kidney Int. 84: 104-115, 2013) after application of mechanical stress (Endlich et al., J. Am. Soc. Nephrol. 12: 413-422, 2001) as compared to control conditions. Elevated glomerular pressure represents a high risk for the development of severe kidney diseases and causes an increase of mechanical load to podocytes. In this study we investigated whether mechanical stress alters gene expression in cultured podocytes using gene arrays. We found that tetraspanin CD9 is significantly upregulated in cultured podocytes after mechanical stress. The differential expression of CD9 was confirmed by RT-PCR and Western blot under stretched and unstretched conditions. Furthermore, mechanical stress resulted in a relocalization of CD9. To get an insight into the functional role of CD9, podocytes were transfected with pEGFP-CD9. The expression of CD9 induced the formation of substratum-attached thin arborized protrusions (TAPs). Ca2+ depletion revealed that podocytes over-expressing CD9 possess altered adhesive properties in contrast to the control transfected cells. Finally, elevated CD9 expression increased migration of podocytes in a wound assay. In summary, our results suggest that upregulation of CD9 may play an important role in podocyte morphology, adhesion and migration. Three independent batches were used.
