IPSC-derived cardiomyocytes at the single-cell level

ABSTRACT: Currently, cardiomyocytes differentiated from human induced pluripotent stem cells (iPSCs) are routinely generated for disease research and drug development as an alternative to animal models. To assess which cell types are present at day 30 of differentiation, we conducted single-cell RNA sequencing using a female and a male line. Our analysis showed that the majority (84-87%) of cells express marker genes typical of cardiomyocytes. Most iPSC-CMs display either ventricular-like (40%) or atrial-like (35-39%) gene expression profiles, whereas a small subset (8-9%) correspond to immature, proliferative cells. The remaining cells expressed extracellular matrix genes and typical epicardial markers. Most likely, these cells underwent suboptimal WNT inhibition following mesoderm induction and differentiated along an epicardial-derived lineage, as reported previously.

The transcriptome of human iPSC-derived cardiomyocytes

Project description:Currently, cardiomyocytes differentiated from human induced pluripotent stem cells (iPSCs) are routinely generated for disease research and drug development as an alternative to animal models. Although iPSC-derived cardiomyocytes (iPSC-CMs) are generally assumed to resemble myocytes in the fetal heart, a systematic global comparison is still lacking. We established a robust differentiation protocol to generate mature cardiomyocytes from male and female iPSC lines, and investigated their gene expression and splicing profiles, compared to that of human hearts at different stages of development.

Ethanol Exposure during Differentiation of Human Induced Pluripotent Stem Cells Reduces Cardiomyocyte Generation and Alters Metabolism

Project description:In this study, we investigated the effects of ethanol exposure on cardiomyocyte differentiation by treating the cells with various concentrations of ethanol. The results indicated that ethanol exposure during hiPSC-CM differentiation reduced cell viability, cell proliferation, and cardiomyocyte yield, and caused mitochondrial dysfunction, redox imbalance, and changes of proteomic profiles.

Single-cell RNA-seq of a three-dimensional multilineage human organogenesis model showing endothelial-to-hematopoietic-transition in vitro

Project description:Multilineage differentiation of human embryonic stem cells into three-dimensional (3-D) model, termed as progressed elongated embryoid bodies (peEBs), recapitulates crucial features of early human development, including cardio myogenesis and haematopoiesis. Characterisation of peEBs at transcriptome and protein levels at different stages of development to study embryonic haematopoiesis and endothelial-to-hematopoietic-transition (EHT) in vitro.

RNA-seq of hESCs undergoing primed to naive-like resetting via exogenous KLF17 overexpression

Project description:RNA-seq of H9 human embryonic stem cells cultured under naive pluripotency-supportive PXGL conditions either with (Dox) or without (UI) exogenous KLF17 expression for five days. As well as a day 0 control sample (hESCs 24hrs after plating in mTeSR), both UI and +Dox samples were collected at days 1, 2 and 5 after switching to naive-permissive PXGL culture conditions. Only Dox-induced hESCs survive after the first passage and form stable lines in PXGL with naive-like morphology and transcriptome, which could be maintained until naive passage 5 (p5).

Modulation of the bulk cell density as decisive parameter and simple method for mesendodermal patterning of human pluripotent stem cells

Project description:1 million human pluripotent cells cultured as suspension aggregates (hES3-NKX2.5 cell line) were treated with 0, 7.5 or 15µM CHIR99021 in 1 or 3 ml RPMI/B27 (w/o insulin) for 24h to induce the differentiation of human pluripotent stem cells (hPSCs). CHIR99021 is a potent GSK3 inhibitor that results in prominent WNT pathway activation and thereby induces mesendodermal differentiation.

microRNA expression profiling among human embryonic stem cells, differerentiated EBs and adult cells

Project description:Human embryonic stem (hES) cells have unique features: self-renewal ability and pluripotency. They can be continuously cultured in undifferentiated state and give rise to cells and tissues of all three germ layers. Thus hES cells provide a resource not only for cell replacement therapy but also for studying human developmental biology. We aimed to identify the unique signature of miRNAs in human embryonic stem cells. Keywords: cell type comparison design We performed microRNA expression profiling on 3 passages from 2 different hES cell lines (WA09 (H9) and BG01v) and 4 passages from 1 hES cell line (TE06 (I6)), EBs samples derived from WA09 cells at 4 different time points with replicates, and 5 types of adult cells (HUVEC, HMVEC, UASMC NHA, and LFB).

Impairment of autophagic flux by combined EGFR and ROCK inhibition leads to triple-negative breast cancer cell death

Project description:Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with very limited therapeutic options. We have recently shown that the combined inhibition of EGFR and ROCK in TNBC cells results in cell cycle arrest and ultimately cell death. However, the underlying mechanisms by which co-inhibition of EGFR and ROCK induces cell death remain unclear. To investigate the synergistic effect of the combination treatment on TNBC cells, in the present study we applied a mass spectrometry-based proteomic approach to identify proteins altered upon single and combination treatments.

The impact of early WNT pathway inhibition (day 1 of differentiation) during human pluripotent stem cell differentiation towards cardiomyocytes

Project description:Human pluripotent stem cells were aggregated in mTeSR medium for 4 days and subjected to an optimzed small molecule-based cardiac differentiation protocol (modified from Kempf et. al., Stem Cell Reports, 2014) in agitated Erlenmeyer flasks. Differentiation was induced using 7.5µM CHIR99021 (day 0). Cardiac mesoderm specification was carried out using 5µM IWP2 either directly after CHIR99021 exposure after 24h (day 1; optimized protocol) or after 72h hours (day 3; standard procedure). RNA samples were harvested at undifferentiated state (day 0), after differentiation induction (day 1) and after 3 days with and without IWP2 treatment.

Melanoma NRAS - Cooperative induction of apoptosis in nras mutant melanoma by inhibition of mek and rock

Project description:In the present work we propose a new therapy for NRAS mutant melanoma. Simultaneous inhibition of MEK and ROCK caused induction of BimEL , PARP, and Puma, and hence apoptosis. In vivo, MEK and ROCK inhibition suppressed growth of established tumors. Our findings warrant clinical investigation of the effectiveness of combinatorial targeting of MAPK/ERK and ROCK in NRAS mutant melanoma.
