Kidney organoids derived from human induced pluripotent stem cells (iPSC)

ABSTRACT: iPSCs were maintained on Geltrex coated flat culture dish in E8 media according to manufacturer’s guidelines. Colonies were manually harvested at 60-80% confluence. Cells were then collected and dissociated into single cells using EDTA. Cells were put on to ultra low attachment 24 well or 96 well plate to allow them to form aggregated in suspension with ROCK inhibitor. Cell aggregates 191were cultured in E8 medium with daily medium change for 6-7 days. Control iPSC-A (iPSC-aggregates) were plated on a Geltrex in 96 well plate or 8 well culture chamber. And then aggregates were treated E8 medium with daily medium change for 12-14 days.

RNA-seq of hiPSCs adapted to homemade weekend-free media

Project description:Homemade weekend free media are a promising way for the labs to reduce the manpower and high costs associated with the culture of human induced pluripotent stem cells (hiPSCs) in feeder-free conditions. However, as these media would have a different concentration of various growth factors, cells may perceive a change in the signalling environments and change their transcription profile. To investigate the extent of this change, we decided to perform RNA sequencing and study the change of gene expression as compared to cells grown in commercial, daily changed E8.

Identification of adaptive mechanisms leading to reduced antibiotic susceptibility in bacterial biofilms using experimental evolution. Part 3: Pseudomonas aeruginosa floating biofilms in synthetic cystic fibrosis medium

Project description:Pseudomonas aeruginosa was repeatedly and intermittently exposed to tobramycin. Bacteria were grown in synthetic cystic fibrosis medium in wells of a 96-well microtiter plate. After 24 hours, more medium with or without tobramycin was added. After another 24 hours of incubation, a subsample of the well content was used to inoculate fresh synthetic cystic fibrosis medium in a 96-well microtiter plate. This was repeated for a total of 15 cycles. Evolved lineages were then DNA-sequenced to screen for genome changes.

Generation of feederless iPS cell from human cord blood cells using Sendai virus (SeV) vector

Project description:CD34+ fraction of cord blood (CB) cells can be reprogrammed on pronectinF-coated dish in serum free medium using Sendai virus (SeV) vector carrying reprogramming factors OCT3/4, SOX2, KLF4 and c-MYC. human ES cell-like colonies came to merge around 18 days after SeV infection on pronectin-coated dish in human ES cell medium supplemented with bFGF under normoxic culture (20% O2). After passages, dish like-shape colonies were seeded on pronectinF-coated 96 well-plate in a single cell and cultured in N2B27 based medium supplemented with LIF, FK, MAPKi, GSKi in hypoxic culture condition (5% O2) for cloning purpose. Emerged dome shape colonies were collected and cultured in human ES cell medium supplemented with bFGF under normoxic culture (20% O2) again. Dish shape and human ES cell-like colonies derived from single cell were picked up for further appraisal of reprogrammed cells such as expression of pluriotency–related molecules. Reprogrammed cells can be maintained for more than 20 passages without differentiation.

Transcriptomic profile of human induced pluripotent stem cells at single cell resolution.

Project description:We assessed the pluripotency of human induced pluripotent stem cells (iPSCs) maintained on an automated platform using StemFlexTM and TeSRTM-E8TM media. Single-cell transcriptome sequencing was performed for 20,962 cells from two cell lines grown in the two media. Analysis of transcriptomic profile revealed similar expression of core pluripotency genes, as well as genes associated with naive and primed states of pluripotency. Single cell analysis of the four samples revealed a shared subpopulation structure with three main subpopulations different in pluripotency states. By implementing a machine learning approach, we estimated that 60-96% of the cells in the ground/naive subpopulations and 98-99% of the cells in the primed subpopulations are similar between all four samples. The single cell RNA sequencing analysis of iPSC lines grown in both media is the first report of the molecular pathways modulated in StemFlex medium and how they compare to those modulated in TeSR-E8 medium.

Transcriptome profiling of human anaplastic meningioma IOMM-Lee cells following silencing of HuR (Human antigen R) gene expression by siRNA

Project description:The human anaplastic meningioma IOMM-Lee cells were cultured in Dulbeccoâs modified Eagleâs medium (Life Technologies, Carlsbad, California, USA) supplemented with 10% fetal bovine serum, 100 U/ml penicillin, and 100 mg/ml streptomycin, at 37Â°C in 20% O2 (5% CO2). HuR silencing was achieved by transfecting cells in a 96 well-plate with 500 Âµl per well of culture medium containing 10 Âµl of siRNA (Silencer Select siRNA ELAVL1 s4608; Ambion, Life Technologies; 1 Âµmol/L),1 ÂµL of RNAiMAX lipofectamin and 89 ÂµL of opti-MEM (Life Technologies). Negative control cells were obtained under the same conditions using the Silencer Select Negative Control siRNA#1 (Ambion, Life Technologies). All assays were performed in sextaplicates.

Gene expression profiles in human iPS cells cultured by different four methods

Project description:Hepatocyte-like cells differentiated from human iPS cells are expected to be utilized in pharmaceutical research and regenerative medicine. Recently, various culture methods for human iPS cell maintenance have been developed. However, it is not well known whether human iPS cell maintenance method affects hepatic differentiation potency. In this study, we cultured human iPS cells using four maintenance methods: ReproStem medium with feeder cells (mouse embryonic fibroblasts), AK02N medium with iMatrix-511 (E8 fragments of laminin511), Essential 8 medium with Vitronectin N (N-terminal domain of vitronectin), TeSR-E8 medium with Vitronectin XF (xeno-free vitronectin). Then, these human iPS cells were differentiated into the hepatocyte-like cells. Interestingly, the gene expression levels of definitive endoderm markers in the definitive endoderm cells generated from human iPS cells cultured with ReproStem or TeSR-E8 medium were higher than those in other groups. The gene expression level of foregut marker, HHEX, in the definitive endoderm cells generated from human iPS cells cultured with ReproStem medium was higher than that in other groups. Consistently, the expression levels of hepatocyte markers, albumin and urea secretion capacity, and CYP3A4 activity in the hepatocyte-like cells generated from human iPS cells cultured with ReproStem medium were higher than those in other groups. Our data indicated that the most suitable human iPS cell maintenance method for efficient hepatic differentiation was the on-feeder method which uses mouse embryonic fibroblasts, but not feeder-free methods. In conclusion, human iPS cell maintenance method largely affects hepatic differentiation potency.

Human serum-derived protein removes the need for coating in defined human pluripotent stem cell culture

Project description:Reliable, scalable and time-efficient culture methods are required to fully realize the clinical and industrial applications of human pluripotent stem (hPS) cells. Here we present a completely defined, xeno-free medium that supports long-term propagation of hPS cells on uncoated tissue-culture plastic. The medium consists of the Essential 8 (E8) formulation supplemented with Inter-α-inhibitor (IαI), a human serum-derived protein, recently demonstrated to activate key pluripotency pathways in mouse PS cells. IαI efficiently induces attachment and long-term growth of both embryonic and induced hPS cell lines when added as a soluble protein to the medium at seeding. IαI-supplementation efficiently supports adaptation of feeder-dependent hPS cells to xeno-free conditions, clonal growth as well as single-cell survival in the absence of Rho-associated kinase inhibitor (ROCKi). This time-efficient and simplified culture method paves the way for large-scale, high-throughput hPS cell culture, and will be valuable for both basic research and commercial applications.
