Gene expression in human keratinocytes cultivated with serum-free medium and serum containing medium

Project description:The objective of this study was thus to develop ab initio that chemically defined serum-free medium. We used a statistical design of experiment (DOE) approach to screen a large number of candidate factors, for both their potential individual and synergetic effects, as to identify a formulation which was then tested extensively. In this study, we present the properties of keratinocyte cultivated with serum-Free medium (Surge SFM) and complemented DME-Ham medium (with serum).

Characterization of human dental pulp cells grown in chemically defined serum-free medium

Project description:Dental pulp cells obtained from several donors proliferated actively in a serum-free medium STK2. The growth rate of dental pulp cells from most donors was higher in the serum-free medium than that in a medium containing 10% serum. DNA microarray analyses showed that gene expression profile of dental pulp cells grown in the serum-free medium was similar to that of cells grown in a medium containing 10% serum. However, several genes related to cell proliferation were up-regulated in dental pulp cells grown in the serum-free medium.

RNA-seq of Mycoplasma pneumoniae grown in serum-free medium

Project description:We developed a serum and animal component-free medium capable of supporting robust growth of the genome-reduced bacterium Mycoplasma pneumoniae. Here, we performed RNA-seq expression analysis of the wild-type strain grown in serum-free vB13 medium.

Label-free shotgun proteomics of Mycoplasma pneumoniae grown in serum-free medium

Project description:We developed a serum and animal component-free medium capable of supporting robust growth of the genome-reduced bacterium Mycoplasma pneumoniae. Here, we analyzed the proteome of the wild-type strain grown in serum-free vB13 medium compared to rich medium (Hayflick medium).

Epigenome and transcriptome of naive pluripotent mouse embryonic stem (ES) cells cultured in 2i serum-free medium

Project description:This study describes the epigenetic and transcriptome profiling of mouse ES cells cultures in 2i serum-free medium. The proteins for which ChIP-Seq profiles were generated in these cells, as well as for cells grown in serum conditions, include H3K4me3, H3K36me3, H3K27me3, H3K9me3, Suz12 and Ezh2. A sequence profile of genomic DNA is also included. Furthermore, we included RNA-Seq of ds_cDNA synthesized from double poly(A) selected mRNA and from rRNA depleted (strand specific) total RNA.

Gene Expression Profile of Human Umbilical Cord Mesenchymal Stem Cells (hUC-MSCs) Culutured in Chemical Defined Serum Free Medium

Project description:Human umbilical cord mesenchymal stem cells maintained multipotency and immunosuppressive ability when being cultured in chemical defined serum free medium, but gained different gene expression profile. We used microarrays to identify the transcriptional difference between human umbilical cord mesenchymal stem cells cultured in serum containing medium and chemical defined serum free medium. human umbilical cord mesenchymal stem cells were cultured in conventional serum containing medium and chemical defined serum free medium separately. Total RNA was extracted and hybridized on Affymetrix microarrays.

Ascorbate effect on serum free cultured hESC

Project description:Ascorbate activates CD30 expression and causes widespread specific demethylation of the epigenome of serum free cultured hESC. The genetic and epigenetic integrity of human Embryonic Stem cells (hESCs) is critical to their future applications in research and medicine. hESC cultured in serum free media can accumulate point mutations, aneuploidy and progressive epigenetic changes over prolonged culture in vitro. We have identified ascorbate as the only molecule in the very widely used Knock-out serum replacement medium that is sufficient to induce expression of CD30, a biomarker for aneuploidy in hESCs. In fact, we show that hESC cultured in the presence of ascorbate for 20 passages not only display demethylation of the CD30 locus, but exhibit widespread and remarkably specific and consistent demethylation of 1,847 genes in both HES2 and HES3 cells. The specific ascorbate induced demethylation changes in the hESC epigenome, of which 86% are shared between the two lines, identify a subset of genes in hESC, including CD30, that are sensitive to serum free culture medium induced epigenetic changes. Experiment. HES2 cells were maintained on 20% Fetal calf serum on mouse embryonic fibroblast feeder layers with mechanical dissection. Using HES2 after 99 mechanical passages (P99), hESC were grown for 17-20 (+17 - +20) passages in the presence of 20% Knock-Out Serum Replacement (Invitrogen) either with (+ASC) or without (-ASC) Ascorbate with enzymatic culturing.
