RNA-sea of Smad4 wild-type or Smad4 knockout KPC PDAC organoids from monocultures or co-cultures with pancreatic stellate cells and RNA-seq of flow-sorted PSCs from the same co-cultures.

Project description:RNA-sequencing of flow-sorted Smad4 wild-type (WT) or Smad4 knockout (KO) KPC (i.e. KRASG12D; p53 mutant) pancreatic ductal adenocarcinoma (PDAC) organoids from monocultures or co-cultures with pancreatic stellate cells (PSCs) and RNA-sequencing of flow-sorted PSCs from the same co-cultures. We investigated changes in transcriptome in Smad4 KO KPC PDAC organoids compared to Smad4 WT KPC PDAC organoids in monoculture or in co-culture with PSCs. We also investigated the changes in transcriptome in PSCs co-cultured with Smad4 WT or Smad4 KO KPC PDAC organoids.

Gene expression profiles of epithelial and mesenchymal cells extracted from heterotypic ex vivo co-cultures or monocultures

Project description:Stromal-epithelial interactions play a fundamental role in tissue homeostasis, controlling cell proliferation and differentiation. Not surprisingly, aberrant stromal-epithelial interactions contribute to malignancies. The goals and objectives of this study were 1.) to characterize and validate the molecular identity of human primary epithelial and stromal/mesenchymal breast cells maintained long-term in novel ex vivo culture conditions in serum free medium. 2.) To analyze changes in gene expression profiles of normal human primary epithelial and stromal/mesenchymal breast cells upon long-term ex vivo co-culture when compared to corresponding monocultures 3.) To study the dynamic reciprocity between normal human primary epithelial and stromal/mesenchymal breast cells. 4.) To identify critical molecular pathways and biomarkers controlling epithelial and/or stromal cell growth and quiescence. Human primary epithelial progenitor cells and mesenchymal stem cells bearing fluorescent tags were either co-cultured in novel ex vivo culture conditions on ECM coated meshes in serum free medium (M5) or cultured as monocultures in the same conditions for 30 days. The cultures were then dissociated and epithelial and stromal/mesenchymal cells from either co-cultures or monocultures separated by FACS. Gene expression profiling of epithelial or stromal/mesenchymal cells was performed. Clean gene expression profiles from three different epithelial and stromal/mesenchymal cell extracts either grown in co-cultures or monocultures were successfully obtained.

Gene expression of LNCaP cells grown in polyethlene glycol-based hydrogels alone (monocultures) and grown with human osteoblasts as tissue engineered bone (co-culture) with the presence of synthetic androgen, R1881

2014-05-13 | GSE44143 | GEO

Project description:Analysis of LNCaP cell molecular differences in monocultures and in co-cultures in the presence of R1881. Human osteoblast molecular signatures were also identified from the tissue engineered bone monocultures. LNCaP cells molecular profile was altered by co-culturing with human osteoblasts compared to LNCaP monocultures with or without R1881 stimulations. These results provide insights into the behavioral change of LNCaP cells in a bone-like microenvironment. In this study, LNCaP cells cultured in the hydrogel were prepared and co-cultured with or without human osteoblasts (in the form oftissue engineered bone). Similarly, tissue engineered bone monocultures were also prepared 4-6 weeks earlier before co-culturing with the LNCaP cells. These cultures were maintained up to 24 days in RPMI growth media (+10% FBS) before they were androgen-starved for 48 hours. Cells were either treated with 1nM R1881 or continued to be androgen-deprived (without R1881 with 0.008% ethanol) for another 48 hours prior to cell harvest for gene expression analysis. Biological triplicates were prepared for each condition.

RNAseq of Pseudomonas aeruginosa PAO1 and Staphylococcus aureus USA300 in monocultures and co-cultivated at 37ºC and 39ºC in microaerobiosis

Project description:Staphylococcus aureus USA300 and Pseudomonas aeruginosa PAO1 were cultured in microaerobiosis (sealed bottles using a 1:4 medium-to-flask volume ratio without agitation) in Triptic Soy Broth (TSB; Oxoid) supplemented with 0.5% KNO3. S. aureus and P. aeruginosa monocultures were inoculated at a DO600 of 0.05 and incubated for 2h at 37°C. After that, cultures were split in two and furtherly incubated for 2h at 37°C (control) or 39°C (heat shock). A similar protocol was employed for co-culture experiments, where S. aureus and P. aeruginosa were co-inoculated each at a DO600 of 0.05 and followed the same protocol.

Sacrificial cell death of adipose mesenchymal stem cells by autophagy facilitates cartilage formation in co-cultures with chondrocytes

Project description:Objective: Cartilage formation is stimulated in mixtures of chondrocytes and human adipose-derived mesenchymal stem cells (MSCs) both in vitro and in vivo. During co-culture, human MSCs perish through an unknown process. The goal of this study is to elucidate the mechanism by which adipose tissue-derived MSC cell death occurs in the presence of chondrocytes. Methods: Human primary chondrocytes were co-cultured with human MSCs derived from three donors. The cells were cultured in mono-culture or co-culture (20% chondrocytes and 80% MSCs) in pellets (200.000 cell/pellet) for 7 days in chondrocyte proliferation media in hypoxia (2% O2). RNA sequencing was performed to assess for differences in gene expression between monocultures or co-culture. Western blot and immune fluorescence assays were performed to quantify the level of Caspase-3, LC3B and P62. Results: RNA sequencing revealed significant up-regulation of >90 genes in the three co-cultures when compared to monocultures. STRING analysis showed interconnections between >50 of these genes. Remarkably, 75% of these genes play a role in cell death pathways such as apoptosis and autophagy. Western blotting shows a clear up-regulation of the autophagic machinery with no substantial activation of the apoptotic pathway. Conclusion: In co-cultures of human MSCs with primary chondrocytes, MSCs perish through autophagy. We propose that this sacrificial cell death may perhaps contribute to the trophic effects of MSCs on cartilage formation.
