Single-Cell RNA Sequencing of Human Embryonic Stem Cells and Feeder-free Extended Pluripotent Stem Cells

ABSTRACT: This dataset features transcriptomic profiles of feeder-free extended pluripotent stem cells (ffEPSCs) and their parentalderived from human embryonic stem cells (ESCs). ffEPSCs were generated using a Matrigel-based feeder-free system combined with a chemical cocktail to convert conventional ESCs into ffEPSCs. Generated using Smart-seq2 and sequenced on Illumina HiSeq 2000, the dataset explores transcriptional profiles and heterogeneity of ESCs and ffEPSCs, providing insights into early human development and stem cell biology.

The single-cell transcriptome data of pig embryonic stem cells cultured without feeder cells

Project description:Here, we examined the effect of LDN-193189, an inhibitor of the BMP signaling pathway, on pig embryonic stem cells (ESCs) in the absence of feeder cells to develop a feeder-free culture system. Feeder cells play an important role in supporting the pluripotency of pig ESCs by blocking trophoblast and mesodermal differentiation through inhibition of the BMP pathway. Transcriptome analysis revealed that LDN-193189 treatment instead of coculturing with feeder cells could help maintain the pluripotency and homogenous cell population of pig ESCs by stimulating the secretion of chemokines and suppressing differentiation. We confirmed that LDN-193189-treated pig ESCs cultured without feeder cells maintained pluripotency for an extended period and were capable of differentiating in vivo and in vitro. The pig ESCs represented distinct characteristics of pig epiblasts as an in vivo counterpart at a transcriptomic level. In summary, we developed feeder-free culture systems for pig ESCs, and our findings will improve the understanding of pluripotency gene networks and comparative embryogenesis.

Feeder-Independent Derivation of Induced-Pluripotent Stem Cells From Peripheral Blood Endothelial Progenitor Cells

Project description:The objective of this study was to reprogram peripheral blood-derived late-endothelial progenitor cells (EPCs) to a pluripotent state under feeder-free and defined culture conditions. Late-EPCs were retrovirally-transduced with OCT4, SOX2, KLF4, c-MYC, and iPSC colonies were derived in feeder-free and defined media conditions. EPC-iPSCs expressed pluripotent markers, were capable of differentiating to cells from all three germ-layers, and retained a normal karyotype. Transcriptome analyses demonstrated that EPC-iPSCs exhibit a global gene expression profile similar to human embryonic stem cells (hESCs). We have generated iPSCs from late-EPCs under feeder-free conditions. Thus, peripheral blood-derived late-outgrowth EPCs represent an alternative cell source for generating iPSCs.

Methanol fixed feeder layers altered the pluripotency and metabolism of bovine pluripotent stem cells

Project description:The pluripotency maintenance of pluripotent stem cells (PSCs) cultured in vitro requires the suitable microenvironment, which is commonly provided by the feeder layer. However, the preparation of feeder layer is time consuming and labor exhaustive. More importantly, the feeder cells treated with mitomycin or gamma-ray irradiation brings heterologous contamination to stem cells. The feeder-free PSC cultures are associated with high costs because of the requirement for additional supplements and special media. In this study, we characterize the pluripotency and metabolic status of bovine ESCs-F7 (classic bESCs lines, abbreviated as F7), which were cultured on methanol fixed mouse embryonic fibroblasts (MT-MEFs) or mitomycin C treated MEFs (1M-MEFs). MT-MEFs could be reused several times and were highly resistant to digestive enzymes. The relative expression levels of pluripotent markers were different between F7 cultured on MT-MEFs (marked as MT-F7) and those cultured on the 1M-MEFs (1M-F7). The long-term cultured MT-F7 cells formed embryoid bodies in vitro, showing the ability to differentiate into endodermal, ectodermal, and mesodermal germ layers like 1M-F7. RNA-sequencing analysis showed that the replacement of the feeder layer from 1M-MEFs to MT-MEFs lead to a novel steady transition of the F7, which included alteration of the expression patterns of genes that regulate pluripotency and metabolism. Further, the long-term cultured bovine expanded pluripotent stem cells (bEPSCs) on MT-MEFs (MT-bEPSCs) formed classical colonies, maintained pluripotency, and demonstrated elevated level of metabolic activity. In conclusion, this study demonstrated that methanol-fixed MEFs were efficient feeder layer that maintain the unique pluripotency and the distinctive metabolic characteristics of the bPSCs cultured in vitro.

Human iPSCs derived under feeder free conditions displays an unqiue cell cycle and DNA replication genotype

Project description: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. These feeder-free derived iPSCs are in many ways similar to feeder-derived iPSCs and also to hESCs, with respect to their pluripotent gene expression (OCT4, NANOG, SOX2), protein expression (OCT4, NANOG, SSEA4, TRA160) and differentiation capabilities. We conducted a whole genomic transcript analysis using Affymetrix Human Gene 1.0 ST arrays to elucidate the important differences between traditional feeder-derived iPSCs and feeder-free derived iPSCs. We reveal that feeder-free iPSCs have over-represented terms belonging to DNA replication and cell cycle genes which are lacking in feeder-derived iPSCs. Feeder-free iPSCs are in many aspects more similar to hESCs including; apoptosis, chromatin modification enzymes and mitochondrial energy metabolism. We have also identified potential biomarkers for fully reprogrammed iPSCs (FRZB) and partially reprogrammed iPSCs (POTEG, MX2) based on their expression trends across all cell types. In conclusion, feeder-free derived iPSCs is transcriptomically more similar to hESCs than feeder derived iPSCs, in many biological functions.
