Expression analysis of λH1-hESC derived β-like cells

ABSTRACT: Purpose: Pancreatic islet transplantation is an effective cell therapy for type 1 diabetes (T1D), but its clinical application is limited by the shortage of donor pancreata. Among the potential alternatives, the differentiation of human embryonic stem cells (hESc) into insulin-producing β-cells has taken an early lead. However, while the proportion of β-cells obtained through current methods is relatively high, a significant percentage of undefined non-endocrine cell types are still generated. Most importantly, there is the potential for carry-over of non-differentiated cell types that may produce teratomas upon transplantation. In order to address these issues, we sought to modify hESc so that their differentiated progeny could be selectively devoid of tumorigenic cells and enriched for cells of the desired phenotype (in this case, pancreatic β-cells). Methods: mRNA profiles of λH1-hESC derived β-like cells were developed by mRNA sequencing, in triplicate, using Illumina HiSeq PE Cluster Kit v4 and Illumina HiSeq Flow Cell v4 with 50 nt paired end reads plus dual index reads using the Illumina HiSeq SBS kit v4. Sequence reads that passed quality filters were analyzed at the transcript isoform level following alignment using TopHat v2.1.0 followed by exon and gene level counting using Bioconductor easyRNASeq v 2.4.7. Conclusions: Our study demonstrates that λH1-hESC derived β-like cells have a transcriptional expression profile similar to ESC derived β-like cells.

Expression analysis of BMP7 responsive P2RY1/ALK3 expressing progenitor like cells within the human exocrine pancreas

Project description:Purpose: Here we demonstrate ALK3Bright/PDX1+ cells residing within the human pancreatic ducts have progenitor like characteristics. Using flow cytometery, live-cell sorting of ALK3bright/PDX1+ cells is possible using a surrogate surface marker for PDX1 (P2RY1). Treating ALK3bright/P2RY1+ cells with BMP7 results in their expansion. Later removal of BMP7 results in the differentiation of these cells to β-like cells. Here we compare the mRNA expression profiles of these three different cell types (in triplicate). Methods: mRNA profiles of ALK3Bright/P2RY1+ cells isolated from human non-endocrine pancreatic tissue, ALK3Bright/P2RY1+ cells treated with BMP7 and ALK3Bright/P2RY1+ cells differentiated to β-like cells after BMP7 removal were generated by deep sequencing, in triplicate, using Illumina HiSeq PE Cluster Kit v4 and Illumina HiSeq Flow Cell v4 with 50 nt paired end reads plus dual index reads using the Illumina HiSeq SBS kit v4. Sequence reads that passed quality filters were analyzed at the transcript isoform level following alignment using TopHat v2.1.0 followed by exon and gene level counting using Bioconductor easyRNASeq v 2.4.7. Conclusions: Our study represents the first detailed analysis of ALK3Bright/P2RY1+ sorted cells with biological replicates. We demonstrate ALK3Bright/P2RY1+ cells were shown to form progenitor-like epithelial colonies characterized by NKX6.1 and PDX1 expression. Unlike the negative fraction controls, these colonies responded to BMP-7 by generating new β-like cells as well as cells from other pancreatic lineages. The transcriptional profile of these cells and their BMP7 treated counterparts suggest a mitotic and progenitor like state. Our studies confirm the progenitor-like nature of ALK3Bright/PDX1+ cells within the human pancreas and suggest a specific anatomical location within the ductal network.

SUFU and SPOP mediated downregulation of Hh signaling promotes pancreatic beta-cell differentiation through the regulation of organ-specific stromal niche signals

Project description:Purpose: Human Embryonic Stem Cell (hESC)-derived insulin-producing beta cells offer a promising cell-based therapy for diabetes. However, efficient hESC to beta cell differentiation has proven difficult, possibly due to the lack of cross-talk with the appropriate mesenchymal niche. To define organ-specific niche signals, we isolated pancreatic and gastrointestinal stromal cells and analyzed their transcriptomes during development. Methods: mRNA profiles from E13.5 mice were generated from mesenchymal cells dissected from wild-type (WT) intestine, stomach, pancreas and mutant Sufu-/- Spop -/- pancreatic mesenchyme, in duplicate, by illumina HiSeq 2500. Reads were aligned to the mm10 assembly and unambiguously mapping reads were analyzed at the gene level for differential expression between tissue types alignment using STAR and differential analysis using DESeq2. Results: Using our workflow, we mapped about 30 million reads per sample to mm10. Differential expression (DE) analysis identified over 900 significantly differentially expressed genes between WT pancreatic mesenchyme and gastrointestinal mesenchymes, and over 1100 genes differentially expressed between WT and mutant pancreatic mesenchyme. Our findings reveal the importance of tightly-regulated Hh signaling in the pancreatic mesenchyme. In vivo inactivation of mesenchymal Hh signaling leads to annular pancreas, and stroma-specific activation of Hh signaling via loss of Hh regulators, Sufu and Spop, impairs pancreatic growth and beta cell genesis. Genetic rescue and transcriptome analyses show that these Sufu and Spop knockout defects occur through GLI2-mediated activation of gastrointestinal stromal signals such as Wnt ligands. Importantly, inhibition of Wnt signaling in organoid and hESC cultures significantly promotes insulin-producing cell generation, revealing the requirement for organ-specific regulation of stromal niche signals.

Total RNA sequencing of IFN-stimulated and HIV-1-infected macrophages

Project description:Monocyte-derived macrophages were stimulated with 25 ng/ml of the indicated IFNs or infected with HIV-1-BaL-HSA. Total RNA was isolated 18 h following stimulation/infection using RNeasy minikit (Qiagen). Intact poly(A) RNA was purified from total RNA samples (100 to 500 ng) with oligo(dT) magnetic beads, and stranded mRNA sequencing libraries were prepared as described using the Illumina TruSeq Stranded mRNA Library Preparation kit (catalog no. RS-122-2101 and RS-122-2102). Purified libraries were qualified on an Agilent Technologies 2200 TapeStation using a D1000 ScreenTape assay (catalog no. 5067-5582 and 5067-5583). The molarity of adapter-modified molecules was defined by quantitative PCR using the Kapa Biosystems Kapa Library Quant kit (catalog no. KK4824). Individual libraries were normalized to 10 nM, and equal volumes were pooled in preparation for Illumina sequence analysis. Sequencing libraries (25 pM) were chemically denatured and applied to an Illumina HiSeq v4 single-read flow cell using an Illumina cBot system. Hybridized molecules were clonally amplified and annealed to sequencing primers with reagents from an Illumina HiSeq SR cluster kit v4-cBot (catalog no. GD-401-4001). Following transfer of the flow cell to an Illumina HiSeq 2500 instrument (HCSv2.2.38 and RTA v1.18.61), a 50-cycle single-read sequence run was performed using HiSeq SBS kit v4 sequencing reagents (catalog no. FC-401-4002).

Project description:Purpose: Diffuse large B cell lymphomas (DLBCL) frequently harbor mutations in the histone acetyltransferase CREBBP, however their functional contribution to lymphomagenesis remains largely unknown. This study aims at elucidating and characterizing the molecular pathways affected by mutations in CREBBP. Methods: U2932, a DLBCL cell line that has wild type expression of CREBBP was manipulated by CRISPR-Cas9 strategy to mutate one allele of CREBBP and examine the pathways affected. RNA was isolated using the NucleoSping RNA Kit (Macherey-Nagel) from five wild type (CREBBP+/+) and five heterozygous clones (CREBBP+/-). RNA quality was assessed by Bioanalyzer 2100 followed by library preparation using the TruSeq RNA Sample Prep Kit v4 (Illumina). Sequencing was subsequently performed on the Illumina HiSeq 2500 instrument. RNA-seq reads were quality-checked with fastqc, which computes various quality metrics for the raw reads. RNA-seq reads were mapped to the GRCh38 reference human genome using STAR and reads were counted according to Ensembl gene annotation using the featureCounts function in the Rsubread Bioconductor package. Statistical analysis of differential expression was conducted with the DESeq2 package.
