Inducible three-factor direct reprogramming to nephron progenitors using piggyBac transposons

ABSTRACT: All nephrons in the mammalian kidney arise from a transient nephron progenitor population that is lost after birth. The recreation of nephron progenitors (NPs) and/or their maintenance in culture has been a major focus of renal regenerative strategies. Using a lentiviral screening approach, we previously generated an induced nephron progenitor (iNP) state in vitro using a pool of six transcription factors (SIX1, SIX2, HOXA11, OSR1, EYA1, SNAI2). Here, using an inducible piggyBac transposon system, we demonstrate efficient reprogramming to iNPs with only three transcription factors (SNAI2, EYA1 and SIX1). Coupled with maintenance in culture conditions supportive of this progenitor state, the resulting population can contribute to developing nephrons in vitro, ex vivo and in vivo. This approach provides a rapid and efficient method for the generation of NPs from human somatic cells.

Chromatin remodelers interact with Eya1 and Six2 to control nephron progenitor cell self-renewal maintenance

Project description:Eya1 interacts with Six1/2 to induce nephron fate and promote nephron progenitor self-renewal. Haploinsufficiency for these genes in humans causes kidney agenesis or hypoplasia. However, how the Eya1-centered network operates remains elusive. Here we identify Eya1's interacting factors via mass-spectrometry and show that Eya1 and Six2 interact with Brg1-based SWI/SNF chromatin-remodeling complex in the kidney. Depletion of Brg1 results in lack of metanephric mesenchyme and depletion of nephron progenitor cells, which is linked to loss of Eya1 expression. Transcriptional profiling reveals conspicuous downregulation of the proto-oncogene Pbx1 and the Dchs1/Fat4 signaling but premature upregulation of a large subset of genes for podocyte lineages and aberrant activation of oncogenic factors in Brg1-deficent cell. ChIP-seq identifies Brg1-occupancy to enhancers at Pbx1 to a distal enhancer of Eya1 that drives nephron progenitor-specific expression. We demonstrate Six2-dependent Brg1 enrichment to the proximal-promoter of Mycn and two distal enhancers of Pbx1, all of which govern nephron progenitor-specific expression in response to binding to Six2. Together, our results suggest a possible mechanism through which the functional specificity of Brg1-BAFs and Eya1-Six2 in cell cycle regulation and self-renewal of the nephron progenitors may be in part achieved.

Transcriptional profiling of human and mouse nephron progenitor cells

Project description:Nephron endowment is determined by the self-renewal and induction of a nephron progenitor pool established at the onset of kidney development. In the mouse, the related transcriptional regulators Six1 and Six2 play non-overlapping roles in nephron progenitors. Transient Six1 activity prefigures, and is essential for, active nephrogenesis. In contrast, Six2 maintains later progenitor self-renewal from the onset of nephrogenesis. We compared Six2’s regulatory actions in mouse and human nephron progenitors by chromatin immunoprecipitation followed by DNA sequencing (ChIP-seq). Surprisingly, SIX1 was identified as a SIX2 target unique to the human nephron progenitors. Further, RNA-seq and immunostaining revealed overlapping SIX1 and SIX2 progenitor activity in the 16 week human fetal kidney. Human SIX1 ChIP-seq revealed a similar set of targets to SIX2, and predicted both factors bind DNA through an identical recognition site. In contrast to the mouse where Six2 binds its own enhancers but doesn’t interact with DNA around Six1, both human SIX1 and SIX2 bind homologous SIX2 enhancers and putative enhancers positioned around SIX1. Transgenic analysis of a putative human SIX1 enhancer in the mouse revealed a transient, mouse-like, pre-nephrogenic, Six1 regulatory pattern. Together, these data demonstrate a divergence in SIX-factor regulation between mouse and human nephron progenitors. In the human, an auto/cross-regulatory loop drives continued SIX1 and SIX2 expression during active nephrogenesis. In contrast, the mouse establishes only an auto-regulatory Six2 loop. It is tempting to speculate that differential SIX-factor regulation may contribute to species differences in the duration of progenitor programs and nephron output.

Six1 and Six2 of the sine oculis homeobox subfamily are not functionally interchangeable in mouse nephron formation

Project description:The vertebrate Six1 and Six2 arose by gene duplication from the Drosophila so (sine oculis) and have since diverged in their developmental expression patterns. Both genes are expressed in nephron progenitors of human fetal kidneys, and mutations in SIX1 or SIX2 cause branchio-oto-renal or renal hypodysplasia respectively. Since ~80% of SIX1 target sites are shared by SIX2, it is speculated that SIX1 and SIX2 may be functionally interchangeable by targeting common downstream genes. In contrast, in mouse kidneys, the expression of Six1 and Six2 only transiently overlaps in the metanephric mesenchyme before the onset of ureteric branching, and only Six2 expression is maintained in the nephron progenitors throughout development. This non-overlapping expression between Six1 and Six2 in mouse nephron progenitors promoted us to examine if Six1 can replace Six2. Surprisingly, forced expression of Six1 failed to rescue Six2-deficient kidney hypoplasia. We found that Six1 mediated Eya1 nuclear translocation and inhibited premature epithelialization of the progenitors but failed to rescue the proliferation defects and cell death caused by Six2-knockout. Genome-wide binding analyses showed that Six1 only bound to a small subset of Six2 target sites, but many Six2-bound loci that are crucial to the renewal and differentiation of nephron progenitors lacked Six1 occupancy. Thus, these data indicate that Six1 cannot substitute Six2 to drive nephrogenesis in mouse kidneys, demonstrating that these two transcription factors have not maintained equivalent biochemical properties since their divergence early in vertebrate evolution.

Repression of interstitial cell identity in nephron progenitor cells by Pax2 establishes the nephron-interstitium lineage boundary throughout mammalian kidney development

Project description:The kidney contains the functional units, the nephrons, surrounded by the renal interstitium. Previously, we discovered that, once Six2-expressing nephron progenitor cells and Foxd1-expressing renal interstitial progenitor cells form at the onset of kidney development, descendant cells from these populations contribute exclusively to the main body of nephrons and renal interstitial tissues, respectively, indicating a lineage boundary between the nephron and renal interstitial compartments. Currently, it is unclear how lineages are regulated during kidney organogenesis. We demonstrate that nephron progenitor cells lacking Pax2 activity failed to differentiate into nephron cells, but can switch fates into renal interstitium cell types. These data suggest that Pax2 function maintains nephron progenitor cells by repressing transdifferentiation into renal interstitial cell states. Thus, the lineage boundary between the nephron and renal interstitial compartments is maintained by the Pax2 activity in nephron progenitor cells during kidney organogenesis.

SWI/SNF chromatin remodelers target enhancers via interaction with Eya1 and Six2 to specify metanephric fate and maintain nephron progenitor pool

Project description:Eya1 is a critical regulator for establishing nephron fate and acts upstream of Six2. However, how Eya1-centered network operates remains elusive. Here we identified Eya1's interacting factors via mass-spectrometry and show that Eya1 and Six2 interact with Brg1-based SWI/SNF chromatin-remodeling complex in the kidney. Brg1 specifies the nephron fate and regulates Eya1 expression through binding to multiple cis-regulatory-elements. In the nephron-progenitors, Brg1/Six2 co-occupy cis-regulatory-elements at key loci and Brg1-recruitment to many of these regions is disrupted in the absence of Six2. We demonstrate Six2-dependent Brg1-occupancy to Mycn promoter and two distal enhancers of Pbx1, all of which direct nephron-progenitor-specific expression in response to binding to Six2. RNA-seq analysis reveals that depletion of Brg1 leads to upregulation of genes for podocyte-lineages and aberrant activation of cell-death inducing factors. Together, this study highlights an essential function of the Brg1-BAFs in cooperation with Eya1/Six2 in enhancer-mediated regulation of gene expression in the nephron-progenitors.

The chromatin remodeler Brg1 cooperates with tissue-specific transcription-factors to regulate Sox2 activation via multiple enhancers to establish proneurosensory identity within otic ectoderm

Project description:Specification of Sox2+ proneurosensory progenitors within otic ectoderm is a prerequisite for the production of sensory cells and neurons for hearing. However, the underlying molecular mechanisms driving this lineage specification remain unknown. Here, we show that Brg1-based SWI/SNF chromatin-remodeling complex interacts with the neurosensory-specific transcriptional regulators Eya1/Six1 to induce Sox2 expression and proneurosensory-lineage specification. Ablation of the ATPase-subunit Brg1 or both Eya1/Six1 results in loss of Sox2 expression and lack of neurosensory identity. Brg1 and Six1 co-occupy three distal 3' Sox2 enhancers and Brg1-recruitment to these regions is disrupted in Eya1- or Six1-null otocyst. Eya1 as a coactivator of Six1 synergistically regulates the activity of these enhancers, which drives expression in otic neurosensory cells in response to binding to Six1. Thus, through interaction with Six1/Eya1, the Brg1-based SWI/SNF complex specifies otic proneurosensory lineage. Furthermore, genome-wide and transcriptome analyses reveal that Brg1 also suppresses expression of non-otic genes.

Tet2 and Tet3 mediated active cytosine hydroxymethylation in Six2 progenitor cells is critical for nephron progenitor differentiation and nephron endowment

Project description:Nephron endowment is a key determinant of later life hypertension and kidney disease. Here we studied whether epigenetic changes, specifically the ten–eleven translocation (Tet) DNA demethylase family, Tet1, Tet2, and Tet3-mediated active DNA hydroxymethylation is necessary for gene expression regulation and kidney differentiation. We generated mice with deletion of Tet1, Tet2 or Tet3 in Six2 positive nephron progenitors (NP). We did not observe changes in development or kidney function in mice with nephron progenitor-specific deletion of Tet1, Tet2, Tet3 or Tet1/Tet2 or Tet1/Tet3. On the other hand, mice with combined Tet2 and Tet3 loss in Six2-positive NPCs failed to form nephrons leading to kidney failure and perinatal death. Tet2 and Tet3 loss in Six2-positive NPs resulted in defect in mesenchymal to epithelial transition and renal vesicle differentiation. Whole genome bisulfite sequencing, single cell RNA sequencing, and gene and protein expression assay identified a defect in expression in genes in the WNT-β-catenin signaling pathway in absence of Tet2 and Tet3 due to a failure in demethylation of these loci. Our results indicate the key role of Tet2 and Tet3-mediated active cytosine hydroxymethylation in NPs in kidney development and nephron endowment.

Chromatin remodelers and lineage specific factors interact to target enhancers to establish pro-neurosensory fate within otic ectoderm

Project description:Specification of Sox2+ pro-neurosensory progenitors within otic ectoderm is a prerequisite for the production of sensory cells and neurons for hearing. However, the underlying molecular mechanisms driving this lineage specification remain unknown. Here, we show that Brg1-based SWI/SNF chromatin-remodeling complex interacts with the neurosensory-specific transcriptional regulators Eya1/Six1 to induce Sox2 expression and promote pro-neurosensory-lineage specification. Ablation of the ATPase-subunit Brg1 or both Eya1/Six1 results in loss of Sox2 expression and lack of neurosensory identity, leading to abnormal apoptosis within the otic ectoderm. Brg1 binds to two of three distal 3' Sox2 enhancers occupied by Six1, and Brg1-binding to these regions depends on Eya1-Six1 activity. We demonstrate that the activity of these Sox2 enhancers in otic neurosensory cells specifically depends on binding to Six1. Furthermore, genome-wide and transcriptome profiling indicate that Brg1 may suppress apoptotic factor Map3k5 to inhibit apoptosis. Together, our findings reveal an essential role for Brg1, its downstream pathways, and their interactions with Six1/Eya1, in promoting pro-neurosensory fate induction in the otic ectoderm and subsequent neuronal lineage commitment and survival of otic cells.

Genome-wide maps of SIX1, SIX2, and active loci in human fetal kidneys generated from ChIP-seq data.

Project description:SIX2 is expressed by the self-renewing nephron progenitors in the human fetal kidney. We have also discovered that SIX1 is expressed in nephron progenitor population of the human fetal kidney, which is in contrast to the mouse. We performed ChIP-seq of SIX1 and SIX2 in order to identify the target genes of each factor and compare the role that each factor plays in transcriptional regulation of the nephron progenitors. We additionally performed ChIP-seq for p300 and H3K27ac in order to identify active loci and complement the transcription factor data.
