(Submitter supplied) We monitored 9 pluripotent stem cell lines across three time points of hepatic directed differentiation, representing 3 developmental stages: undifferentiated (T0), definitive endoderm (T5), and early hepatocyte (T24). ESCs (n=3) and patient-derived normal (n=3) or PiZZ (n=3) iPSCs were analyzed in the undifferentiated state (T0), after differentiation to definitive endoderm (T5), and upon reaching hepatic stage (T24) for a total of 27 samples. more...

(Submitter supplied) Recent studies suggested that embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) may represent different pluripotent states as defined by gene expression profiles and differentiation potential. Here we addressed a contribution of a lineage stage-specific donor cell memory in modulating the functional properties of iPSCs. iPSCs were generated from hepatic lineage cells at an early (hepatoblast-derived, HB-iPSCs) and end stage (adult hepatocyte, AH-iPSCs) of hepatocyte differentiation as well as from mouse fetal fibroblasts (MEF-iPSCs) using a lentiviral vector encoding four pluripotency-inducing factors Oct4, Sox2, Klf4, and c-Myc. more...

(Submitter supplied) Human induced pluripotent stem cells (hIPSCs) represent a unique opportunity for regenerative medicine since they offer the prospect of generating unlimited quantities of cells for autologous transplantation as a novel treatment for a broad range of disorders. However, the use of hIPSCs in the context of genetically inherited human disease will require correction of disease-causing mutations in a manner that is fully compatible with clinical applications. more...

(Submitter supplied) We profiled the global transcriptomes of 10 featured AATD-patient specific iPSC that underwent directed differentiation towards a hepatic and lung lineage. We used digital gene expression (DGE), a platform for high-fidelity RNA sequencing, and in addition to differentiated iPSC-derived cell types mentioned above (iHeps and iPSC-Lung progenitors), we also collected RNA from undifferentiated iPSCs and from a panel of primary adult human hepatocytes (PHH) for comparison.

(Submitter supplied) Transgenic PiZ mice have been genetically engineered to express ATZ and have been a valuable experimental model for studing liver disease associated with AAT deficiency. ATZ accumulates in these mice within the ER of hepatocytes in a nearly identical manner to livers of affected patients. To investigate the pathogenesis of liver damage induced by ATZ, we performed gene expression analysis in livers of 6-week-old PiZ mice and strain-, age-, and gender-matched wild-type mouse controls. more...

(Submitter supplied) Skin fibroblasts from individuals with PBD-ZSD, a rare autosomal recessive disorder caused by peroxisome assembly defects, show defects in lipid metabolism that provide the basis for clinical diagnostic tests, but are not among the cell types most affected by disease. To explore phenotypes of more clinically relevant cell types, skin fibroblasts from PBD-ZSD patients and healthy controls were reprogrammed into iPS cells with all the hallmark properties of pluripotency. more...

(Submitter supplied) Induced pluripotent stem cells (iPSCs) are similar to embryonic stem cells and can be generated from somatic cells. We have generated episomal plasmid-based and integration-free iPSCs (E-iPSCs) from human fetal foreskin fibroblast cells (HFF1). E-iPSCs were fully characterized and their transcriptomes are more similar to that of hESCs (R2 = 0.9363) in comparison to viral-derived HFF1-iPSCs (R2 = 0.8176). more...

(Submitter supplied) Limbal epithelial stem cell (LESC) deficiency represents a significant clinical problem especially in bilateral cases. Induced pluripotent stem cells (iPSC) may be a promising source of LESC, allowing standardized and continual propagation and banking. The objective of this study was to generate iPSC from human limbal epithelial cultures and differentiate them back into limbal epithelial cells using substrata mimicking the natural LESC niche. more...

(Submitter supplied) The human embryonic stem cells (hESCs) are a unique model system for investigating the mechanisms of human development due to their ability to replicate indefinitely while retaining the capacity to differentiate into a host of functionally distinct cell types. In addition, these cells could be potentially used as therapeutic agents in regenerative medicine. Differentiation of hESCs involves selective activation or silencing of genes, a process controlled in part by the epigenetic state of the cell. more...

(Submitter supplied) Here we performed genome-wide RNA-seq and Reduced Representation Bisulfite Sequencing (RRBS-seq) in isogenic human induced pluripotent stem cells (iPSCs) and somatic cell nuclear transfer-derived embryonic stem cells (nt-ESCs), genetically matched in vitro fertilization-derived ESCs (IVF-ESCs), and their respective differentiated cells (cardiomyocytes and endothelial cells). We generated the transcriptome and DNA methylome map in human pluripotent stem cells and their differentiated cells with single-nucleotide resolution. more...

(Submitter supplied) Two independent protocols for deriving HLCs from hESCs and iPSCs were adopted and further characterization included immunocytochemistry, real-time RT-PCR, and in vitro functional assays. Comparative microarray-based gene expression profiling was conducted on these cells and compared to the transcriptomes of human fetal liver and adult liver progenitors. HLCs derived from hESCs and hiPSCs showed significant functional similarities, similar expression of genes important for liver physiology and common pathways. more...

(Submitter supplied) Induced pluripotent stem cells (iPSCs) have been generated from various somatic cells under feeder-layer conditions. These feeder-derived iPSCs generated in different labs exhibit greater variability than between different traditional embryo derived hESC lines. For that reason, it is important to develop a standard and defined system for deriving autologous patient stem cells. We have generated iPSCs under feeder-free conditions using Matrigel coated vessels in chemically defined medium, mTeSR1. more...

(Submitter supplied) Human induced pluripotent stem cells (iPSCs) - derived mesenchymal stromal cells (iMSCs) are a potentially useful cell type for circumventing ageing-related shortfalls associated with primary mesenchymal or skeletal stromal cells (MSCs/SSCs). To date, the extent of the reflection of ageing-hallmarks in iMSCs differentiated from iPSCs derived from elderly donors remains unclear. In this study, we show that fetal (55 days post conception) femur-derived MSCs and MSCs isolated from aged (60 – 74 years) donors differ in their transcriptome and secretome profile. more...

(Submitter supplied) Recent studies showed that Induced pluripotent stem cells (iPSCs) could hold memory of their origin and exhibit skewed differentiation potential. This finding reveals a severe limit for the application of iPSCs in cell-based therapy in case certain cell types are not available for reprograming from patients. Here we show that under a typical condition for mammary differentiation, iPSCs derived from mouse mammary epithelium cells (ME-iPSCs) exhibit mammary signature gene expression and chromatin epigenetic modification, leading to smooth progress for mammary gland formation. more...
