Genome wide expression profiling of mesenchymal stem cells of fetal and adult origin and dermal fibroblasts

ABSTRACT: In animal models and human trials, intramyocardial injection of adult bone-marrow derived mesenchymal stem cells (BM-MSC) provides beneficial effects in failing hearts. These effects are mainly mediated through paracrine mechanisms. Mesenchymal stem cells of fetal origin (hAMC) can be isolated from the amniotic membrane of human placenta. Our results provide evidence that hAMC exert remarkable cardioprotective effects through paracrine mechanisms. However, the complete nature and scope of the paracrine mediators of cardioprotection have not been investigated yet. We compared the gene expression profiling of hAMC (n=8), BM-MSC (n=10) and dermal fibroblasts (n=6) to shed light onto the identity of putative cardioprotective factors secreted by fetal MSC.

Project description:Background: Mesenchymal stromal cells (MSC) have been proposed as a future cell based therapy for lung diseases like bronchiolitis obliterans syndrome (BOS). Theoretically, it might be beneficial to use lung resident MSC already adapted to the pulmonary environment. We therefore aimed to compare lung MSC with the well-characterized bone marrow MSC. Furthermore, MSC isolated from lung-transplanted patients with BOS were compared to MSC isolated from good outcome recipients. Methods: MSC were isolated from bone marrow (BM) and adult/fetal lung tissues and compared by a comprehensive panel of assays. Results:The gene expression profiles of adult lung derived and fetal lung derived MSC were very similar compared to BM derived MSC, with only 235 and 338 genes, respectively, being significantly differently expressed. Out of the 235 genes that were significantly different between adult lung derived and BM derived MSC, 90 genes were higher expressed in the lung derived MSC. In case of fetal lung derived MSC, 166 genes were higher expressed compared to the BM derived MSC. Interestingly, only, 89 genes were found to be expressed differently when comparing BM derived MSC to both, fetal and adult lung derived MSC, indicating that these genes are lung specific. Next, we went on to evaluate if MSC isolated from biopsies of lung-transplanted patients with BOS differed compared to patients without BOS, i.e. good outcome recipients. Here we found that four genes (Sox9, FAR2, LOC728855 and NDUFS5) were significantly higher expressed in MSC isolated from BOS patients Conclusions: This data demonstrates that lung resident MSC possess lung specific properties that should be taken into considerations when using MSC for cell-based therapy in severe lung disorders like BOS. These results also show that MSC isolated from lung-transplanted patients with BOS do not have an altered phenotype.
