AbstractDifferentiation of human pluripotent stem cells into insulin-producing stem cell-derived beta cells harbors great potential for research and therapy of diabetes. The SOX9 gene plays a crucial role during development of the pancreas and particularly in the development of insulin-producing cells as SOX9+ cells form the source for NEUROG3+ endocrine progenitor cells. For the purpose of easy monitoring of differentiation efficiencies into pancreatic progenitors and insulin-producing cells, we generated new reporter lines by knocking in a P2A-H-2Kk-F2A-GFP2 reporter genes into the SOX9 locus and a P2A-mCherry reporter gene into the INS locus mediated by CRISPR/CAS9-technology. The knock-ins enable co-expression of the endogenous genes and reporter genes, report the endogenous gene expression and enable the purification of pancreatic progenitors and insulin-producing cells using FACS or MACS. Using these cell lines we established a new differentiation protocol geared towards SOX9+ cells to efficiently drive human pluripotent stem cells into glucose-responsive beta cells.

Chemical Functionality

It is shown that hydroxyl functionality is required to induce stasis in human embryonic stem cell colonies immersed within wholly synthetic block copolymer worm gels with comparable storage moduli. Thus gel softness does not appear to be an essential parameter for stasis induction.

Background: Umbilical cord blood (UCB) used to be considered waste material and was discarded at birth. However, cord blood is now considered a rich source of adult stem cells that can be used to treat many conditions and diseases. This study was performed to determine pregnant women’s knowledge and attitudes toward cord blood stem cell banking and donation in Lebanon. Methods: A descriptive study was conducted in antenatal clinics in Beirut and data were collected using a questionnaire distributed to pregnant women after provision of informed consent. A total of 244 women responded. Results: Less than half of the women (46%) reported knowledge about cord blood banking. However, participants with university and secondary education had significantly higher odds of considering UCB storage compared to those with primary education (odds ratio (OR) 8.62, 95% confidence interval (CI) 2.74–27.15 and OR 21.23,95% CI 6.55–68.86, respectively). Older pregnant women were less likely to think about UCB stem cells storage (OR 0.92, 95% CI 0.85–0.98). Conclusion: Respondents who had an existing knowledge about UCB stem cells banking in general were more likely to consider storing UCB in blood banks if affordable (45.9%). Therefore, it is necessary to inform pregnant women about stem cell banking so that they can make the appropriate decisions for themselves.

Human pluripotent stem cells can in principle be used as a source of any differentiated cell type for disease modelling, drug screening, toxicology testing or cell replacement therapy. Type I diabetes is considered a major target for stem cell applications due to the shortage of primary human beta cells. Several protocols have been reported for generating pancreatic progenitors by in vitro differentiation of human pluripotent stem cells. Here we first assessed one of these protocols on a panel of pluripotent stem cell lines for capacity to engender glucose sensitive insulin-producing cells after engraftment in immunocompromised mice. We observed variable outcomes with only one cell line showing a low level of glucose response. We, therefore, undertook a systematic comparison of different methods for inducing definitive endoderm and subsequently pancreatic differentiation. Of several protocols tested, we identified a combined approach that robustly generated pancreatic progenitors in vitro from both embryo-derived and induced pluripotent stem cells. These findings suggest that, although there are intrinsic differences in lineage specification propensity between pluripotent stem cell lines, optimal differentiation procedures may consistently direct a substantial fraction of cells into pancreatic specification.

ABSTRACTRetinal organoids generated from human pluripotent stem cells exhibit considerable variability in temporal dynamics of differentiation. To assess the maturity of neural retina in vitro, we performed transcriptome analyses of developing organoids from human embryonic and induced pluripotent stem cell lines. We show that the developmental variability in organoids was reflected in gene expression profiles and could be evaluated by molecular staging with the human fetal and adult retinal transcriptome data. We also demonstrated that addition of 9-cis retinal, instead of widely-used all-trans retinoic acid, accelerated rod photoreceptor differentiation in organoid cultures, with higher rhodopsin expression and more mature mitochondrial morphology evident by day 120. Our studies thus provide an objective transcriptome-based modality for determining the differentiation state of retinal organoids, which should facilitate disease modeling and evaluation of therapies in vitro.Summary StatementThree-dimensional organoids derived from human pluripotent stem cells have been extensively applied for investigating organogenesis, modeling diseases and development of therapies. However, substantial variations within organoids pose challenges for comparison among different cultures and studies. We generated transcriptomes of multiple distinct retinal organoids and compared these to human fetal and adult retina gene profiles for molecular staging of differentiation state of the cultures. Our analysis revealed the advantage of using 9-cis retinal, instead of the widely-used all-trans retinoic acid, in facilitating rod photoreceptor differentiation. Thus, a transcriptome-based comparison can provide an objective method to uncover the maturity of organoid cultures across different lines and in various study platforms.
