COLO 320 (Human colorectal cancer cell line) xenograft: Control (Xenograft without rat mesenchymal stem cells (MSCs)) vs Xenograft with rat MSCs

ABSTRACT: Transcriptional profiling of COLO 320 xenograft tumor cells comparing control COLO 320 xenograft without co-implanted rat MSCs with COLO 320 xenograft with co-implanted rat MSCs. The latter makes co-implanted MSCs visualization possible by using MSCs labeled by GFP under FACS and single cell microscopy. Two-condition experiment, COLO 320 xenograft without rat MSCs [COLO320 MSC(-)] vs. COLO 320 xenograft with rat MSCs [COLO320 MSC(+)]. Biological replicates: 1 control, 1 sample, paired xengraft tumor cells grown and harvested from the same mouse host. One replicate per array.

Expression data of colon cancer COLO320DM cells and tankyrase inhibitor-resistant variant 320-IWR cells

Project description:Wnt/β-catenin signaling is activated in colorectal cancer (CRC) and is involved in CRC growth. Tankyrase, a poly(ADP-ribose) polymerase family member, destabilizes Axin and positively regulates the Wnt/β-catenin signaling. Tankyrase inhibitors efficiently suppress CRC cell proliferation. We established 320-IWR cells, which showed resistance to tankyrase inhibitor IWR-1, from human CRC COLO-320DM cells. We analyzed gene expression profile of 320-IWR cells (320IWR_1,_2) and parental COLO-320DM cells (COLO320_1,_2).

EID1 knochdown by small RNA induces the large-scale conversion of adipose-derived mesenchymal stem cells into hematopoietic stem cells

Project description:Comparison of expression profiles in adipose derived MSCs (AD-MSCs) without or with transfection of siR-EID1 and shR-EID1 and cord blood-derived HSCs (CB-HSCs). After MSCs were transfected with sRNA-EID1, they could be converted into HSCs. The goal was to determine possible molecular mechanisms of MSC transdetermination. Two-condition experiments: AD-MSCs vs CB-HSCs, and AD-MSCs transfected with the combination of siR-EID1 and shR-EID1 vs AD-MSCs transfected with shR-EID1.

Comparison of gene expression profiles in rat sarcomas and masenchymal stem cells (MSCs)

Project description:To investigate the altered patways among sarcomas and MSCs, gene expression profiles were comared among rat osteosarcoma and malignant histiocytoma (MFH) to mesenchymal stem cells (MSCs) from syngeneic origin. Several altered pathways have identified including down-regulation of Wnt, Cell adhesion, ECM interaction and up-regulation of Hedgehog, cell cycling pathways in rat sarcomas compared to MSCs. Gene expression array analysis was perfromed for the samples of rat osteosarcoma COS1NR and malignant fibrous histiocytoma MFH1NR cell lines, bothe established from chemically induced tumors in F344 rats by 4-HAQO, and rat mesenchymal stem cells freshly isolated from femur bone marrow of F344 rats.

Expression data from CD73 positive adipose derived mesenchymal stem cells (CD73+ AD-MSCs) and CD73 negative adipose derived mesenchymal stem cells (CD73- AD-MSCs) of mouse

Project description:MSCs are a heterogeneous population and the specific population of MSCs may exhibit a selective ability for tissue repair. The aim of our research was to adapt the CD73+ subgroup of adipose derived MSCs (AD-MSCs) for the therapy of myocardial infarction (MI). Our results revealed that CD73+ AD-MSCs played more effective role in the acceleration function of cardiac recovery by promoting angiogenesis in a rat model of MI compared to mixed AD-MSCs and CD73- AD-MSCs. Microarray analysis shows differences between CD73+ and CD73- AD-MSCs when transcription profile of these two subgroups were compared, especially in VEGF pathway.

In vivo hyperoxia versus normoxia neonatal rat lung MSCs

Project description:Background: Bronchopulmonary dysplasia (BPD), the most common complication of extreme preterm birth, can be caused by oxygen-related lung injury and is characterized by impaired alveolar and vascular development. Mesenchymal stromal cells (MSCs) have lung protective effects. Conversely, BPD is associated with increased MSCs in tracheal aspirates. Objective: To determine whether endogenous lung (L-)MSCs are perturbed in a well-established oxygen-induced rat model mimicking BPD features. Methods: Rat pups were exposed to room air or 95% oxygen from birth to postnatal day 10. On day 12, CD146+ L-MSCs were isolated and characterized according to the International Society for Cellular Therapy criteria. Epithelial and vascular repair potential were tested by scratch assay and endothelial network formation respectively, immune function by mixed lymphocyte reaction assay. Microarray analysis was performed using the Affymetrix GeneChip and gene set enrichment analysis (GSEA) software. Results: CD146+ L-MSCs isolated from rat pups exposed to hyperoxia had decreased CD73 expression and inhibited lung endothelial network formation. CD146+ L-MSCs indiscriminately promoted epithelial wound healing and limited T-cell proliferation. Expression of potent anti-angiogenic genes of the axonal guidance cue and CDC42 pathways was increased after in vivo hyperoxia, whereas genes of the anti-inflammatory JAK/STAT and lung/vascular growth promoting Fibroblast Growth Factor (FGF) pathways were decreased. Conclusions: In vivo hyperoxia exposure alters the pro-angiogenic effects and FGF expression of L-MSCs. Additionally, decreased CD73 and JAK/STAT expression suggest decreased immune function. L-MSC function may be perturbed and contribute to BPD pathogenesis. These findings may lead to improvements in manufacturing exogenous MSCs with superior repair capabilities.
