Project description:The pooled sample method is used in epigenomic research and expression analysis and is a cost-effective screening approach for small amounts of DNA. Evaluation of the pooled sample method in epigenomic studies is performed using the Illumina Infinium Methylation 450K BeadChip array; however, subsequent reports on the updated 850K array are lacking. A previous study demonstrated that the methylation levels obtained from individual samples were accurately replicated using pooled samples but did not address epigenome-wide association study (EWAS) statistics. The DNA quantification method, which is important for the homogeneous mixing of DNA in the pooled sample method, has since become fluorescence-based, and additional factors need to be considered including the resolution of batch effects of microarray chips and the heterogeneity of the cellular proportions from which the DNA samples are derived. In this study, four pooled samples were created from 44 individual samples, and EWAS statistics for differentially methylated positions (DMPs) and regions (DMRs) were conducted for individual samples and compared with the statistics obtained from the pooled samples.
Project description:Hydroxyapatite (HA) has significant clinical promise for the repair of bone defects and the modification of implant material interfaces. However, after implantation, there are potential risks of chronic inflammation. Dendritic cells (DCs) are key cells in regulating chronic inflammatory responses, and their phenotype and functions are influenced by the surface structure of materials. Therefore, in order to provide some theoretical guidance for the optimal design of HA surface structures, this study tried to construct stepped structures on HA surfaces and investigate the effects of stepped structures on the cytoskeletal, cellular morphology, and mRNA expression profile of immature dendritic cells (imDCs). HA dishes with stepped structures were prepared utilizing the principle of oriented attachment growth, and subsequently used to construct in vitro cell culture models. The imDCs were observed by immunofluorescence staining to characterize their cytoskeleton structures and cellular morphology. Besides, transcriptome sequencing was used to examine the changes in the mRNA expression profile of imDCs. The results indicated that the stepped structures exposed on HA surfaces would increase the spread area of imDCs and affect the cell adhesion morphology. In addition, the results of the transcriptome sequencing revealed significant alterations in the mRNA expression profile, with differentially expressed genes (DEGs) predominantly enriched in the pathways associated with the focal adhesion signal pathway, the chemokine signal pathway, and the IL-17 signal pathway. Thus, the stepped structures could modulatethe cellular morphology and the immunological functions of imDCs by modulating the aforementioned signal pathways, including the focal adhesion pathway, the chemokine signaling pathway, and the IL-17 signaling pathway, thereby affecting the immune response process.
Project description:Kidneys from multiple litters of Six2GFP+ E14.5 mouse embryos were pooled into three replicate tubes and dissociated in parallel. Six2GFP+ cells were isolated and processed for single cell sequencing using 10x Genomics technology. This resulted in a dataset of 7844 single cells representing the nephron progenitor population of the mouse kidney.
Project description:Human primary CD3+ T cells expressing IL13Ra2-targeted chimeric antigen receptors (CARs) that had been identified through high throughput pooled screening were rechallenged with an IL13Ra2+ human glioblastoma cell line , then stained with CITESEQ antibodies indicative of T cell memory and exhaustion state and prepared for single cell sequencing in order to determine their phenotypic responses to chronic tumor challenge relative to that of a clinical standard CAR.
Project description:NCE-SC are inferred as a homogeneous population cultured in the eL-WRN medium (Miyoshi H, Oncotarget 2018;9(31):21950-64.). We used single-cell RNA sequencing (scRNA-seq) to confirm the homogeneity of NCE-SCs.
