Project description:Background: Tissue regeneration and recovery in the adult body depends on self-renewal and differentiation of stem and progenitor cells. Mesenchymal stem cells (MSCs) that have the ability to differentiate into various cell types, have been isolated from the stromal fraction of virtually all tissues. However, little is known about the true identity of MSCs. MSC populations exhibit great tissue-, location- and patient-specific variation in gene expression and are heterogeneous in cell composition. Methodology/Principal findings: Our aim was to analyze the dynamics of differentiation of two closely related stromal cell types, adipose tissue-derived MSCs and dermal fibroblasts (FBs) along adipogenic, osteogenic and chondrogenic lineages using multiplex RNA-seq technology. We found that undifferentiated donor-matched MSCs and FBs are distinct populations that stay different upon differentiation into adipocytes, osteoblasts and chondrocytes. The changes in lineage-specific gene expression occur early in differentiation and persist over time in both MSCs and FBs. Further, MSCs and FBs exhibit similar dynamics of adipogenic and osteogenic differentiation but different dynamics of chondrogenic differentiation. Conclusion: Our findings suggest that stromal stem cells including adipose-derived MSCs and dermal FBs exploit different molecular mechanisms of differentiation to reach a common cell fate. The early mechanisms of differentiation are lineage-specific and are similar for adipogenic and osteogenic differentiation but are distinct for chondrogenic differentiation between MSCs and FBs. A total of 91 samples were analyzed by multiplex RNA-seq. Samples represented replicates from two patients, two cell types and three differentiation protocols, as indicated by the sample annotation. 5 barcodes were unused, but the corresponding FASTQ files are included for completeness.

Project description:Bone marrow (BM) mesenchymal stem/stromal cells are non-hematopoietic (CD45-), non-endothelial (CD31-) multipotential cells capable to differentiate into osteoblastes, chondrocytes and adipocytes. In addition, different subpopulations of MSCs and some of their derivatives (early osteoblastic lineage cells) were shown to form HSC-niche. This makes a complex picture of the relationship between MSCs and HSCs. Despite growing data in mice model, few describe the human counterpart. The BM CD200+ and CD271+ fractions were previously shown to be enriched in native MSCs in human. Herein, we found heterogeneity in expression of CD200 within CD45-/CD31-/CD271+ human BM fraction. We thus selected CD200+ and CD200- cells from CD45-/CD31-/CD271+ BM samples and we analyzed their transcriptome. The differential display of gene expression between these two types of BM fractions will give new insights in the identification of native human MSCs.

Project description:Objective: Craniofacial bone defects caused by injuries and congenital diseases are a formidable challenge to clinicians. Research has shown promise in using bone marrow mesenchymal stem cells (BM-MSCs) from limb bones for craniofacial bone regeneration; yet little is known about the potential of BM-MSCs from craniofacial bones. This study compared BM-MSCs isolated from limb and craniofacial bones in pigs, a preclinical model closely resembling humans. Design: Bone marrow was aspirated from the tibia and mandible of four-month-old pigs (n=4), followed by BM-MSC isolation, culture-expansion and confirmation by flow cytometry. Proliferation rates were compared using population doubling times. Osteogenic differentiation was evaluated by quantifying alkaline phosphatase (ALP) activity. Total mRNA was extracted from freshly isolated BM-MSCs and analyzed to compare gene expressions of tibial and mandibular BM-MSCs using an Affymetrix GeneChip porcine genome array, followed by real-time RT-PCR evaluation of two neural crest markers. Results: BM-MSCs from both locations expressed MSC markers without expression of hematopoietic markers. Mandibular BM-MSCs proliferated significantly faster than tibial BM-MSCs. Without osteogenic inducers, mandibular BM-MSC alkaline phosphatase activities were 3.3-fold greater than those of tibial origin. Microarray analysis identified 383 differentially expressed genes in mandibular and tibial BM-MSCs, including higher expression of cranial neural crest-related genes nestin and BMP-4 in mandibular BM-MSCs, a trend also confirmed by real-time RT-PCR. Among differently expressed genes, only 47 showed greater than 1.5-fold differences in expression. Conclusions: These data indicate that despite many similarities in gene expression, mandibular BM-MSCs express of number of genes differently than tibial BM-MSCs and have a phenotypic profile that may make them advantageous for craniofacial bone regeneration.

Project description:We have previously reported that the deficiency of p53 alone or in combination with Rb (Rb-/- p53-/-) in adipose-derived MSCs (ASCs) promotes leiomyosarcoma-like tumors in vivo. Here, we hypothesized that the source of MSCs and/or the cell differentiation stage could determine the phenotype of sarcoma development. To investigate whether there is a link between the source of MSCs and sarcoma phenotype, we generated p53-/- and Rb-/-p53-/- MSCs from bone marrow (BM-MSCs). Both genotypes of BM-MSCs initiated leiomyosarcoma formation similar to p53-/- and Rb-/-p53-/- ASCs. In addition, gene expression profiling revealed a link between p53- or Rb-p53-deficient BM-MSCs and ASCs and muscle-associated sarcomagenesis. These data suggest that the tissue source of MSC does not seem a crucial factor in the development of a particular sarcoma phenotype. To analyze whether the differentiation stage defines the sarcoma phenotype, BM-MSCs and ASCs were induced to differentiate towards the osteogenic lineage, and both p53 and Rb were excised using Cre-expressing adenovectors at different stages along osteogenic differentiation. Regardless of the level of osteogenic commitment, the inactivation of Rb and p53 in BM-MSC-derived, but not in ASC-derived, osteogenic progenitors gave rise to osteosarcoma-like tumors which could be serially transplanted. This indicates that the osteogenic differentiation stage of BM-MSCs imposes the phenotype of in vivo sarcoma development, and that BM-MSC-derived osteogenic progenitors rather than undifferentiated BM-MSCs, undifferentiated ASCs or ASC-derived osteogenic progenitors, represent the cell of origin for osteosarcoma development.

Project description:Extracellular nucleotides are potent signaling molecules mediating cell-specific biological functions. We previously demonstrated that adenosine 5'-triphosphate (ATP) inhibits the proliferation while stimulating the migration, in vitro and in vivo, of human bone marrow-derived mesenchymal stem cells (BM-hMSC). Here, we investigated the effects of ATP on BM-hMSC differentiation capacity. Molecular analysis showed that ATP treatment modulated the expression of several genes (e.g. wnt-pathway-related genes) governing osteoblastic and adipogenic differentiation of MSCs. Functional studies demonstrated that ATP, under specific culture conditions, stimulated adipogenic and osteogenic differentiation by significantly increasing the lipid accumulation and the expression levels of the adipogenic master gene PPARγ (peroxisome proliferator activated receptor-gamma) and by promoting the mineralization and the expression of the osteoblast-related gene RUNX2 (Runt-related transcription factor 2), respectively. BM-hMSCs cells were transiently exposed to ATP 1mM for 24 hours (ATP pre-treatment) before starting differentiation induction. Then, BM-hMSCs were cultured under adipogenic/osteogenic conditions. Gene Expression Profile was performed on differentiate cells after 3 weeks of induction culture.

Project description:Abnormal osteogenic differentiation of mesenchymal stem cells (MSCs) is implicated in the pathogenesis of Adolescent idiopathic scoliosis(AIS). However, the biological roles of long noncoding RNAs (lncRNAs) in the regulation of osteogenic differentiation of MSCs are unknown. We used LncRNA microarray analyses of bone marrow (BM) MSCs from non-AIS patients and AIS patients and identified significant differentially expressed lncRNAs in AIS BM-MSCs.
