Programmatic Introduction of Parenchymal Cell Types in Blood Vessel Organoids

ABSTRACT: We developed a bottom-up engineering approach to building vascularized human tissue by combining genetic reprogramming with chemically directed organoid differentiation. As a proof of concept, we created neuro-vascular and myo-vascular organoids via transcription factor overexpression in vascular organoids. We characterized neuro-vascular organoids (iN-VOs) by single cell RNA-sequencing (scRNA-seq) to determine cell type composition and gene expression. Using droplet based scRNA-seq we analyzed over 26,000 cells across day 45 organoids grown under three conditions: 45 days of NEUROD1 overexpression (iN-VO, 45 Days Induction), 15 days of NEUROD1 overexpression (iN-VO, 15 Days Induction) and without overexpression (iN-VO, No Induction). We find that organoids contain a neural cell population only upon induction of NEUROD1 while maintaining the full set of endothelial and mesenchymal lineages present in uninduced vascular organoids.

Transcription profiling of Atlantic salmon following dietary substitution of fish oil with vegetable oils

Project description:There is an increasing drive to replace fish oil (FO) in finfish aquaculture diets with vegetable oils (VO), driven by the short supply of FO derived from wild fish stocks. Little is known of the consequences for fish health after such substitution. The effect of dietary VO on hepatic gene expression was determined in Atlantic salmon (Salmo salar) byg a cDNA microarray analysis. Post-smolt farmed salmon were reared for x weeks on diets where the FO component of the feed was replaced with one of three different VOs - rapeseed (RO), soybean (SO) or linseed (LO). RNA from five fish fed on each diet was extracted. A total of 20 cDNA microarray hybridisations - TRAITS / SGP Atlantic salmon 17k feature cDNA microarray - were performed - 4 diets (three VO + FO control) x 5 individuals - using a common pooled reference control design. Data were obtained from 19 of the 20 hybridisations.

A high-resolution single-cell multiomic atlas of the human fetal lung - Organoid

Project description:Individual TFs were overexpressed in fetal lung tip organoids from a doxycycline-inducible construct for 3 days, and organoids were maintained in the self-renewing (tip cell-promoting) medium throughout to rigorously assay the lineage-determining competence of the TF, followed by scRNA-seq. ASCL1, NEUROD1, and NEUROG3 were selected as key neuroendocrine regulators. We also selected the GHRL+ NE-specific RFX6 and NKX2.2, the pan-NE PROX1, and, as controls, the basal cell-specific TFs DeltaNTP63, TFAP2A, PAX9, and mNeonGreen-3xNLS.

Single Nuclei Sequencing of old and young mice hearts under senolytica (Ageing impairs the neuro-vascular interface in the heart)

Project description:Aging is a major risk factor for impaired cardiovascular health. The aging myocardium is characterized by microcirculatory and diastolic dysfunction and increased susceptibility to arrhythmias. Nerves align with vessels during development. However, the impact of aging on the cardiac neuro-vascular interface is entirely unknown. Here, we report that aging reduces nerve density specifically in the left ventricle and dysregulates vascular-derived neuro-regulatory genes. Aging leads to a down-regulation of miR-145 and de-repression of the neuro-repulsive factor Semaphorin-3A. miR-145 deletion, which increased Sema3a expression, or endothelial Sema3a overexpression reduced axon density, thus mimicking the observed aged heart phenotype. Removal of senescent cells, which accumulated with chronological age in parallel to the decline in nerve density, rescued age-induced denervation, reduced Sema3a expression, preserved heart rate variability and reduced electrical instability. These data suggest that senescence-associated regulation of neuro-regulatory genes is associated with reduced nerve density and, thereby, contributes to age-associated cardiac dysfunction.

NeuroD1 reprograms chromatin and transcription factor landscapes to induce the neuronal program

Project description:Cell fate specification relies on the action of critical transcription factors that become available at distinct stages of embryonic development. One such factor is NeuroD1, which is essential for eliciting the neuronal development program and possesses the ability to reprogram other cell types into neurons. Given this capacity, it is important to understand its targets and the mechanism underlying neuronal specification. Here, we show that NeuroD1 directly binds regulatory elements of neuronal genes that are developmentally silenced by epigenetic mechanisms. This targeting is sufficient to initiate events that confer transcriptional competence, including reprogramming of transcription factor landscape, conversion of heterochromatin to euchromatin and increased chromatin accessibility, indicating potential pioneer factor ability of NeuroD1. The transcriptional induction of neuronal fate genes is maintained via epigenetic memory despite a transient NeuroD1 induction during neurogenesis. Our study not only reveals the NeuroD1-dependent gene regulatory program driving neurogenesis but also increases our understanding of how cell-fate specification during development involves a concerted action of transcription factors and epigenetic mechanisms. 1. Ectopic NeuroD1 was induced for 48 hours (+Dox) in ES cells for checking initiation of neuronal transcriptional program in comparison to uninduced condition (-Dox) 2. ChIP-seq was performed after 24 hours of NeuroD1 induction in ES cells.

Cyclosporin ameliorates right ventricular remodeling of postnatal mice with volume overload.

Project description:We reported the RNAseq analyses of right ventricular free wall of myocardium in three groups of mice（3 in each group）at postnatal day 14 (P14). The mice in volume overload (VO) group underwent an abdominal surgery by puncture from aorta to inferior vena cava at P7, mice in Sham group underwent the same surgery except for the puncture. The mice in CsA group were VO mice who were also injected with cyclosporin A(CsA) for seven days. The results revealed that there were differentially expressed genes between VO and sham group at P14, Inhibiting the immune response with CsA caused the gene expression profile of VO mice to shift towards that of sham mice.

Effect of volume overload on right ventricular remodeling in neonatal SD rats

Project description:We reported the RNAseq analyses of right ventricualr free wall myocardium in neonatal volume overload (VO) SD rat. VO was induced by the fistula between abdominal aorta and inferior vena cava (AVF) within 24 hours postnatally (P1). RNAseq analyses of RV free wall at P7 from VO and sham-operated rat revealed that there were 454 differentially expressed genes between VO and sham group at P7. GO analysis showed that in the VO and sham comparison, the upregulated genes mainly mediated immune system response and the downregulated genes mainly mediated apoptotic process at P7. VO has no effect to neonatal right ventricular cardiomyocyte proliferation.

mRNA expression data from adenoma, gene modified, and colorectal cancer organoid.

Project description:We established human colorectal tumor organoids from benign adenoma, primary colorectal cancer or metastasized colorectal cancer. The gene signature of tumor organoids associated with their tumor progression status. We also generated genome-edited organoids from human intestinal organoids recapitulating adenoma-carcinoma sequence. Gene expression signature of the genome engineered organoids were similar to that of adenoma organoids. This result indicated multiple (up to five) genetic mutations were insufficient for gene expression reprogramming of colorectal cancer. We used microarrays to detail the global program of gene expression in human colorectal tumor organoids and artificially mutation introduced organoids. To assess the expression profiling of genome-engineered organoids, we prepared total-RNA from cultured adenoma, carcinoma and genome-engineered organoids. We produced two types of genome-engineered organoids using the CRISPR/Cas9 or lentivirus vector system. Each engineered gene and engineered methods are described as a single alphabet and method name, respectively, in the sample characteristics field. The abbreviations for the engineered genes are as follows. 1) Genome-engineered organoids with CRISPR/Cas9 A = APC deletion; K = KRAS G12V knock in; S = Smad4 deletion; T = TP53 deletion; P = PIK3CA E545K knock in. 2) Genome-engineered organoids with Lent virus vector B = CTNNB1 S33Y overexpression; K = KRAS G12V overexpression; S = Smad4 shRNA overexpression; T = TP53 shRNA overexpression; P = PIK3CA E545K overexpression.
