RNA-seq of definitive endoderm and pancreatic progenitor cells derived in vitro from human pluripotent stem cells in order to study the role of transcription factor GATA6 in human pancreas development

ABSTRACT: Mutant GATA6 hPSCs were obtained by TALEN genome editing or re-programmed from patient fibroblasts. Along with wild-type H9 cells, these GATA6 mutant cell lines were differentiated into SOX17+/CXCR4+ endodermal cells (day 3) and PDX1+ pancreatic progenitor cells (day 12). The purpose of this work was to study the role of GATA6 in the development of the human pancreas at a molecular level.

Heterozygous de novo mutations in GATA6 are the most frequent cause of pancreatic agenesis in humans. In mice, however, a similar phenotype requires the biallelic loss of Gata6 and its paralog Gata4. To elaborate the human-specific requirements for GATA6, we chose to model GATA6 loss in vitro by combining both gene-edited and patient-derived pluripotent stem cells (hPSCs) and directed differentiation toward β-like cells. We find that GATA6 heterozygous hPSCs show a modest reduction in definitive ...[more]

Heparin promotes cardiac differentiation of human pluripotent stem cells in chemically defined albumin-free medium enabling consistent manufacture of cardiomyocytes

Project description:Cardiomyocytes can be differentiated from human pluripotent stem cells (hPSCs) in defined conditions, but efficient and consistent cardiomyocyte differentiation often requires expensive reagents such as B27 supplement or recombinant albumin. Using a chemically defined albumin-free (E8 basal) medium, we identified heparin as a novel factor that significantly promotes cardiomyocyte differentiation efficiency, and developed an efficient method to differentiate hPSCs into cardiomyocytes. The treatment of heparin helped cardiomyocyte differentiation consistently reach at least 80% purity (up to 95%) from more than 10 different hPSC lines in chemically defined DMEM/F-12 based medium on either Matrigel or defined matrices like Vitronectin and Synthemax. One of heparinâs main functions was to act as a WNT modulator that helped promote robust and consistent cardiomyocyte production. Our study provides an efficient, reliable, and cost-effective method for cardiomyocyte derivation from hPSCs that can be used for potential large-scale drug screening, disease modeling, and future cellular therapies. 12 human pluripotent stem cells (hPSCs) at three different cardiac differentiation times (0 Days, 3 Days, 6 Days, 10 Days) under different culture conditions (+/- Heparin, +/- IWP2).

scRNA-seq to investigate endoderm differentiation from induced human pluripotent stem cells

Project description:Single-cell RNA-seq (scRNA-seq) on nocodazole and DMSO treated cells before and after differentiation into endoderm. hPSC colonies were treated with DMSO or 100ng/ml nocodazole for 16 hours and induced to differentiate into definitive endoderm for three days. Single cells were subsequently collected in either undifferentiated conditions (Und) or after 3 days of endoderm differentiation (Endoderm) and then sorted onto 384 well plates for Smart-Seq2 processing.

Single-cell RNA-seq of naive and primed human embryonic stem cells

Project description:This study aims to profile the transcriptomes of single naive and primed human embryonic stem cells. Cells from the H9 line were cultured to select for naive or primed phenotypes, and a sequencing library was generated from each single cell using the Smart-seq2 method. This was repeated for multiple experimental batches, i.e., independent cultures. Batch 1 consists of sequencing runs 2383 and 2384; batch 2 consists of runs 2678, 2679, 2739 and 2740; and batch 3 consists of runs 2780 and 2781. Transcriptional profiles for all cells were obtained from the sequencing data and used to explore substructure and heterogeneity in the population for each phenotype.

Effect of a retinoic acid analogue on BMP-driven pluripotent stem cell chondrogenesis.

Project description:Osteoarthritis is the most common degenerative joint condition, leading to articular cartilage (AC) degradation, chronic pain and immobility. The lack of appropriate therapies that provide tissue restoration combined with the limited lifespan of joint-replacement implants indicate the need for alternative AC regeneration strategies. Differentiation of human pluripotent stem cells (hPSCs) into AC progenitors may provide a long-term regenerative solution but are still limited due to the continued reliance upon growth factors to recapitulate developmental signalling processes. Recently, TTNPB, a small molecule activator of retinoic acid receptors (RARs), has been shown to be sufficient to guide mesodermal specification and early chondrogenesis of hPSCs. Here, we modified our previous differentiation protocol, by supplementing cells with TTNPB and administering BMP2 at specific times to enhance early development.

Development of human cartilage circadian rhythm in a stem cell-chondrogenesis model

Project description:The circadian clock in murine articular cartilage is a critical temporal regulatory mechanism for tissue homeostasis and osteoarthritis. However, translation of these findings into humans has been hampered by the difficulty in obtaining circadian time series human cartilage tissues. As such, a suitable model is needed to understand the initiation and regulation of circadian rhythms in human cartilage. We used a chondrogenic differentiation protocol on human embryonic stem cells (hESCs) as a proxy for early human chondrocyte development. Chondrogenesis was validated using histology and expression of pluripotency and differentiation markers. The molecular circadian clock was tracked in real time by lentiviral transduction of human clock gene luciferase reporters. Differentiation-coupled gene expression was assessed by RNAseq and differential expression analysis.

Directing differentiation of pluripotent stem cells towards retinal pigment epithelium lineage

Project description:Development of efficient and reproducible conditions for directed differentiation of pluripotent stem cells into specific cell types is important not only to understand early human development but also to enable more practical applications, such as in vitro models of disease, drug discovery, and cell therapies. The differentiation of stem cells to retinal pigment epithelium (RPE) in particular holds promise as a source of cells for therapeutic replacement in age-related macular degeneration. Here we show development of a robust and efficient method to derive RPE with high reproducibility in an adherent, monolayer system using sequential inhibition and activation of the Activin and BMP signalling pathways. We use whole genome transcript analysis to characterize cells at different stages of differentiation to gain further understanding of the developmental dynamics and fate specification of RPE.
