PDX1-/NKX6.1+ progenitors derived from human pluripotent stem cells as a novel source of insulin-secreting cells
<p>PDX1-/NKX6.1+ progenitors derived from hESCs were differentiated to pancreatic beta cell stage where they generated glucose-responsive, insulin-secreting cells. The transcriptome profile of hESC- derived PDX1-/NKX6.1+ progenitors were compared with hPSC-derived PDX1+/NKX6.1+ pancreatic progenitors as described in the article entitled "<strong>PDX1<sup>-</sup>/NKX6.1<sup>+</sup>progenitors derived from human pluripotent stem cells as a novel source of insulin-secreting cells</strong>" by Memon et al. 2020. Furthermore, beta cells derived from PDX1-/NKX6.1+ progenitors (3D-beta) were compared with their own endocrine progenitors at an earlier stage (stage 5, 3D-S5) to map their development. </p> <p>The file name is : Sample name_replicate_sample ID_read direction_001 where:</p> <p>-3D-beta: insulin-expressing cells derived from self-detached, 3D, PDX1-/NKX6.1+ progenitors</p> <p>-3D-S5: endocrine progenitors from stage 5, derived from self-detached, 3D, PDX1-/NKX6.1+ progenitors</p> <p>- RNA-seq data were generated from two biological replicates in most cases.</p> <p>- Read direction: R1 (Forward), R2 (Reverse).</p>

Data from: Comparison of osteoclast differentiation protocols from human induced pluripotent stem cells of different tissue origins
<p class="MsoNormal"><span class="apple-converted-space"><span><strong>Background</strong>: </span></span><span class="apple-converted-space"><span>Ever since their discovery, induced pluripotent stem cells (iPSCs) have been extensively differentiated into a large variety of cell types. However, a limited amount of work has been dedicated to differentiating iPSCs into osteoclasts. </span></span><span>While several differentiation protocols have been published, it remains unclear which protocols or differentiation methods are preferable regarding the differentiation of osteoclasts.</span></p> <p class="MsoNormal"><span><strong>Methods</strong>: </span><span>In this study, we compare the osteoclastogenesis capacity of a peripheral blood mononuclear cell (PBMC)-derived iPSC line to a fibroblast-derived iPSC line in conjunction with either embryoid body-based or monolayer-based differentiation strategies. Both cell lines and differentiation protocols were investigated regarding their ability to generate osteoclasts and their inherent robustness and ease of use. The ability of both cell lines to remain undifferentiated while propagating using a feeder-free system was assessed using alkaline phosphatase staining. This was followed by evaluating mesodermal differentiation and the characterization of hematopoietic progenitor cells using flow cytometry. Finally, osteoclast yield and functionality based on resorptive activity, Cathepsin K, and tartrate-resistant acid phosphatase (TRAP) expression were assessed. Results were validated using qRT-PCR throughout the differentiation stages.</span></p> <p class="MsoNormal"><span><strong>Results</strong>: </span><span class="apple-converted-space"><span>Embryoid-body-based differentiation yielded CD45<sup>+</sup>, CD14<sup>+</sup>, and CD11b<sup>+</sup> subpopulations, which in turn differentiated into osteoclasts which demonstrated TRAP positivity, Cathepsin K expression, and mineral resorptive capabilities. This was regardless of which iPSC line was used. Monolayer-based differentiation yielded lower quantities of hematopoietic cells that were mostly CD34<sup>+</sup> and did not subsequently differentiate into osteoclasts.</span></span></p> <p class="MsoNormal"><span class="apple-converted-space"><span><strong>Conclusions</strong>: </span></span><span>The outcome of this study demonstrates the successful differentiation of osteoclasts from iPSCs in conjunction with the embryoid-based differentiation method, while the monolayer-based method did not yield osteoclasts. No differences were observed regarding osteoclast differentiation between the PBMC and fibroblast-derived iPSC lines.</span></p>

Global gene expression profiles of cardiac progenitors differentiated from human pluripotent stem cells in 3D culture under simulated microgravity
Efficient generation of cardiomyocytes from human pluripotent stem cells is critical for their regenerative applications. Microgravity and 3D culture can profoundly modulate cell proliferation and survival. Here we engineered microscale progenitor cardiac spheres from human pluripotent stem cells and exposed the spheres to simulated microgravity using a random positioning machine for 3 days during their differentiation to cardiomyocytes. Methods: RNA-seq libraries were prepared using the Illumina TruSeq RNA kit and the TrueSeq method was employed for mRNA enrichment. The libraries were quantified and samples were multiplexed in each lane of the flowcell. Cluster generation was performed and then sequenced on the Illumina HiSeq1000 system. Reads were mapped on the Human Genome Reference and normalized expression table was generated. Results: Among differentially expressed genes 53 of them were up-regulated and 75 were down-regulated. Conclusions: Data demonstrate increased expression of genes associated with growth development and pro-survival in cardiac progenitors cultured under simulated microgravity compared with those cultured under standard gravity. RNA-sequencing analysis was performed to compare global gene expression profiles of cells at differentiation day 8 under simulated microgravity vs. standard gravity.
Effects of Spaceflight on Human Induced Pluripotent Stem Cell-Derived Cardiomyocyte Structure and Function
With extended stays aboard the International Space Station (ISS) becoming commonplace there is a need to better understand the effects of microgravity on cardiac function. We utilized human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to study the effects of microgravity on cell-level cardiac function and gene expression. The hiPSC-CMs were cultured aboard the ISS for 5.5 weeks and their gene expression structure and functions were compared to ground control hiPSC-CMs. Exposure to microgravity on the ISS caused alterations in hiPSC-CM calcium handling. RNA-sequencing analysis demonstrated 2,635 genes were differentially expressed among flight post-flight and ground control samples including genes involved in mitochondrial metabolism. This study represents the first use of hiPSCs to model the effects of spaceflight on human cardiomyocyte structure and function.
