Project description:Human pluripotent stem cells (hPSCs) have the potential to generate any human cell type, and one widely recognized goal is to make pancreatic β cells. To this end, comparisons between differentiated cell types produced in vitro and their in vivo counterparts are essential to validate hPSC-derived cells. Genome-wide transcriptional analysis of sorted insulin-expressing (INS(+)) cells derived from three independent hPSC lines, human fetal pancreata, and adult human islets points to two major conclusions: (i) Different hPSC lines produce highly similar INS(+) cells and (ii) hPSC-derived INS(+) (hPSC-INS(+)) cells more closely resemble human fetal β cells than adult β cells. This study provides a direct comparison of transcriptional programs between pure hPSC-INS(+) cells and true β cells and provides a catalog of genes whose manipulation may convert hPSC-INS(+) cells into functional β cells RNA is isolated and processed using MARIS from the following samples: H1 human embryonic stem cells (hESCs) in duplicate, HUES8 hESCs in duplicate, human induced pluripotent stem cells (hiPSCs) in duplicate, H1 cells differentiated to a stage in which insulin-expressing cells are present (stage 6) in duplicate, HUES8 cells differentiated to stage 6 in duplicate, hiPSCs differentiated to stage 6, insulin-expressing cells sorted from H1 cells differentiated to stage 6 in duplicate, insulin-expressing cells sorted from HUES8 cells differentiated to stage 6 in duplicate, insulin-expressing cells sorted from hiPSCs differentiated to stage 6 in duplicate, human week 16 fetal pancreata in duplicate, insulin-expressing cells sorted from human week 16 fetal pancreata in triplicate, adult human pancreatic islets in triplicate, and insulin-expressing cells sorted from adult human pancreatic islets in triplicate.

Project description:Abstract: Human pluripotent stem cells (hPSCs) can be directed to differentiate into skeletal muscle progenitor cells (SMPCs). However, the myogenic potential of hPSC-SMPCs compared to human fetal or adult satellite cells (Scs) remains unclear. This study demonstrates hPSC-SMPCs derived by commonly used protocols are functionally less mature than freshly-isolated human fetal or adult Scs. We utilized RNA-SEQ of human fetal Scs to identify differentially expressed genes including NGFR, ERBB3, which enriched for MYOD+ or PAX7+ cells. Furthermore, inhibition of TGFβ (TGFβi) improved hPSC-muscle maturation in three independent lines as measured by TEM and expression of myosins. Engraftment of CRISPR/Cas9-corrected Duchenne Muscular Dystrophy (DMD) hiPSC-SMPC subpopulations treated with TGFβi in vivo, increased dystrophin-positive fibers to levels of engrafted cultured fetal Scs in mdx mouse models of DMD. This work provides the first characterization of the developmental status of hPSC-SMPCs and identifies candidates to enable robust myogenic activity in vitro and in vivo.

Project description:Underdeveloped lungs are the primary cause of death in premature infants, however, little is known about stem and progenitor cell maintenance during human lung development. In this study, we have identified that FGF7, Retinoic Acid and CHIR-99021, a small molecule that inhibits GSK3 to activate Wnt signaling, support in vitro maintenance of primary human fetal lung bud tip progenitor cells in a progenitor state. Furthermore, these factors are sufficient to derive a population of human bud tip-like progenitor cells in 3D organoid structures from human pluripotent stem cells (hPSC). Functional studies showed that hPSC-derived bud tip progenitor organoids do not contain any mesenchymal cell types, maintain multilineage potential in vitro and are able to engraft into the airways of injured mice and respond to systemic factors. We performed RNA-sequencing to assess the degree of similarity in global gene expression profiles between the full human fetal lung (59-127 days gestation), isolated human fetal bud tip progenitors, organoids grown from primary fetal bud tip progenitors, and hPSC-derived bud tip organoids. Results showed that hPSC-derived organoids have molecular profiles similar to organoids generated from primary human fetal lung tissue. Gene expression differences between hPSC-derived bud tip organoids and fetal progenitor organoids may be related to the presence of contaminating mesenchymal cells in primary cultures. hPSC-derived bud tip organoids are generated from a well-defined human cell sources, offering a distinct advantage over rare primary tissue as a means to study human specific lung development, homeostasis and disease.<br>Sample Nomenclature - Description<br> -------------------------------------------------------------------------<br> Peripheral fetal lung the distal/peripheral portion of the fetal lung (i.e., distal 0.5 cm) was excised from the rest of the lung using a scalpel.

Project description:This paper describes the first time a high-content environmental chemicals screen using pancreatic β-like cells derived from human pluripotent stem cells (hPSCs), and discovered that a commonly used pesticide, propargite, induces pancreatic β-cell DNA damage and necrosis. More interestingly, we found out the genetic background of β-like cells affects their response to propargite-induced toxicity, based on isogenic hPSC platform, including for variants GWAS identified associated with T1D, since isogenic GSTT1-/- and PTPN2-/- pancreatic β-like cells are hypersensitive to propargite-induced β-cell death both in vitro and in vivo. In summary, our study identified an environmental chemical that contributes to the loss of β-cells and provides an innovative platform for using hPSC-derived cells to explore gene-environment interactions that impact diabetes disease progression.

Project description:The developmental trajectory of human skeletal myogenesis and the transition between progenitor and stem cell states are unclear. To address this, we employed single cell RNA-sequencing to profile human skeletal muscle tissues from embryonic, fetal and postnatal stages. In silico, we identified myogenic as well as other cell types and constructed a “roadmap” of human skeletal muscle ontogeny across development. In a similar fashion, we also profiled the heterogeneous cell cultures generated from multiple human pluripotent stem cell (hPSC) myogenic differentiation protocols, and mapped hPSC-derived myogenic progenitors to an embryonic-to-fetal transition period. Additionally, we found differentially enriched biological processes and discovered co-regulated gene networks and transcription factors present at distinct myogenic stages. In summary, this work serves as a resource for advancing our knowledge of human myogenesis. It also provides a tool for better characterization and understanding of hPSC-derived myogenic progenitors for translational applications in skeletal muscle based regenerative medicine.

Project description:Understanding distinct gene expression patterns of normal adult and developing fetal human pancreatic a and b cells is crucial for developing stem cell therapies, islet regeneration strategies, and therapies designed to increase b cell function in patients with diabetes (type 1 or 2). Toward that end, we have developed methods to highly purify a, b, and d cells from human fetal and adult pancreata by intracellular staining for the cell-specific hormone content, sorting the sub-populations by flow cytometry and, using next generation RNA sequencing, we report on the detailed transcriptomes of fetal and adult a and b cells. We observed that human islet composition was not influenced by age, gender, or body mass index and transcripts for inflammatory gene products were noted in fetal b cells. In addition, within highly purified adult glucagon-expressing a cells, we observed surprisingly high insulin mRNA expression, but not insulin protein expression. This transcriptome analysis from highly purified islet a and b cell subsets from fetal and adult pancreata offers clear implications for strategies that seek to increase insulin expression in type 1 and type 2 diabetes. RNA-sequencing of highly purified human adult and fetal islet cell subset was performed using our newly developed method. Using this data, we can study and compare the detailed transcriptome or alpha and beta cells during development.

Project description:Heterozygous human INS gene mutations are known to promote ER stress, leading to β-cell dysfunction and neonatal diabetes. Recent literature challenged the long-standing notion that neonatal diabetes occurs due to ER stress-induced β-cell apoptosis. Importantly, mechanisms of β-cell failure during the disease progression and why the other wild-type (WT) INS allele is unable to function still remain unclear. Here, our computational modelling studies, short-term and long-term expression studies in β-cells revealed the presence of ER stress, organelle changes and insulin processing defects, resulting in decreased insulin secretion but not insulin secretory capacity. By nine weeks of expression of mutant INS, dominant negative effects of mutant INS were evident and β-cell insulin secretory capacity declined. INS+/C109Y patient-derived β-like cells and single cell RNA-Sequencing analyses then revealed compensatory upregulation in genes involved in insulin secretion, processing and inflammatory response. Our results provide deeper insights into the mechanisms of β-cell failure during INS mutation-mediated diabetes disease progression. Decreasing CHOP-10, sXBP1 or inflammatory response could be avenues to restore the function of the remaining WT INS allele.

Project description:The generation of insulin-producing pancreatic cells from stem cells in vitro would provide an unprecedented cell source for drug discovery and cell transplantation therapy in diabetes. However, insulin-producing cells previously generated from human pluripotent stem cells (hPSC) lack many functional characteristics of bona fide β cells. Here we report a scalable differentiation protocol that can generate hundreds of millions of glucose-responsive β cells from hPSC in vitro. These stem cell derived cells (SC) express markers found in mature β cells, flux Ca2+ in response to glucose, package insulin into secretory granules and secrete quantities of insulin comparable to adult β cells in response to multiple sequential glucose challenges in vitro. Furthermore, these cells secrete human insulin into the serum of mice shortly after transplantation in a glucose-regulated manner, and transplantation of these cells ameliorates hyperglycemia in diabetic mice. Differentiated cells were sorted and processed for RNA isolation using the MARIS protocol published previously (PMID: 24516164.) Human embryonic stem cell (hESC) line HUES8 was differentiated into SC-beta cells. Two biological replicates were analyzed. Those data were normalized together with and compared to existing, previously published data from Hrvatin et al. ( (PMID: 24516164) from human islet -derived insulin+ cells, undifferentiated HUES8 hES cells, and insulin+ cells derived from HUES8 cells according to previously published protocols.
