Project description:Bone marrow stromal cells (BMSCs) were isolated from the femora and tibiae of irtTA-GBD*-TAg transgenic mice. Using cellular cloning we established skeletal progenitors with unipotent osteogenic and adipogenic properties. Previous RNA-seq analysis of more progenitor types revealed differential expression in members of the Interferon-gamma (IFNγ) signaling pathway. Treatment of adipogenic progenitors with IFNγ inhibited adipogenesis and promoted osteogenesis. RNA-seq analysis of osteogenic, adipogenic and IFNγ treated adipogenic clones revealed factors controlling the osteogenic versus adipogenic commitment of bone marrow skeletal progenitors.

Project description:The healthy growth of adipose tissue depends on the capacity of progenitor cells to undergo denovo adipogenesis. However, the cellular hierarchy and mechanisms governing adipocyteprogenitor differentiation are incompletely understood. Here, we identify a lineage hierarchy25 consisting of distinct mesenchymal cell types present in mouse and human adipose tissue. Cellsmarked by Dpp4 expression are highly proliferative, multipotent progenitors that give rise toIcam1+ committed pre-adipocytes and a related adipogenic population marked by Clec11a andCd142 expression. TGFβ maintains DPP4+ cell identity and inhibits adipogenic commitment ofDPP4+ and CD142+ cells. Intriguingly, DPP4+ progenitors reside in the reticular interstitium that30 envelope many organs including adipose depots. Altogether, this study defines the adipose lineagehierarchy and identifies a new anatomical niche for multipotent mesenchymal progenitors.

Project description:Physical activity improves overall health and counteracts metabolic pathologies. Adipose tissue and bone are important key targets of exercise; the prevalence of diseases associated with suboptimal physical activity levels has increased in recent times as a result of lifestyle changes. Mesenchymal stem cells (MSCs) differentiation in either osteogenic or adipogenic lineage is regulated by many factors. Particularly, the expression of master genes such as RUNX2 and PPARγ2 is essential for MSC commitment to osteogenic or adipogenic differentiation, respectively. Besides various positive effects on health, some authors have reported stressful outcomes as a consequence of endurance in physical activity. We looked for further clues about MSCs differentiation and serum proteins modulation studying the effects of half marathon in runners by means of gene expression analyses and a proteomic approach. Our results demonstrated an increase in osteogenic commitment and a reduction in adipogenic commitment of MSCs. In addition, for the first time we have analyzed the proteomic profile changes in runners after half-marathon activity in order to survey the related systemic adjustments. Interestingly, proteomic data showed the activation of both inflammatory response and detoxification process. Moreover, the involvement of pathways associated to immune response, lipid transport and coagulation, was elicited. Notably, positive and negative effects may be strictly linked.

Project description:To further understand mechanisms governing adipogenic fate commitment, we perform a time course transcriptomic study of progenitors at 0, 3, 7 and 14 days post adipogenic induction. The progenitor cells undergo large scale gene expression changes within 3 days of exposure to adipogenic induction and adiponectin expression is strongly induced at day 3. The early detection of ADIPOQ expression suggests fate commitment occurs within 3 days of induction.

Project description:While the accumulation of bone marrow adipose tissue has been positively associated with aging and high fat diet, the physiological consequences are mostly unknown. It is well established that osteogenic and adipogenic progenitors share a common developmental origin.Unfavorable microenvironmental changes may bias these cell populations towards an adipogenic fate, which in turn could negatively influence bone homeostasis. Our previously collected data from mice reveal a high plasticity of the mesenchymal osteo-adipogenic stem cell population. Therefore, we now wish to perform by RNA-seq in defined cell population with varying adipogenic commitment within this heterogeneous stem cell pool.This data is part of a pre-publication release.

Project description:We demonstrated the multipotent potential and change of cell identity of human adipose tissue-derived progenitors by subjecting cells to adipogenic, chondrogenic, and osteogenic induction. mRNA transcriptomic profiling results demonstrated the detection of lineage-specific markers.

Project description:Bone-marrow mesenchymal stem cells (MSCs) are plastic adherent cells that can differentiate into various tissue lineages, including osteoblasts, adipocytes and chondrocytes. However, this progenitor property is not shared by all cells within the MSC population. In addition, MSCs vary in their proliferation capacities and expression of markers. Because of heterogeneity of CD146 expression in the MSC population, we compared CD146-/Low and CD146High cells under clonal and non-clonal (sorted MSCs) conditions to determine whether this expression is associated with specific functions. CD146-/Low and CD146High MSCs did not differ in colony-forming unit-fibroblast number, osteogenic and adipogenic differentiation or in vitro hematopoietic supportive activity. However, CD146-/Low clones proliferated slightly but significantly faster than did CD146High clones. In addition, a strong expression of CD146 molecule was associated with a commitment towards a vascular smooth muscle cell lineage with upregulation of calponin-1 expression. Thus, within a bone-marrow MSC population, certain subpopulations characterized by high expression of CD146, are committed toward a vascular smooth muscle cell lineage. Clonal MSC were selected on the basis of CD146 level at their surface (CD146Low and CD146 High) and non-clonal MSC were compared from 4 different donors.

Project description:Our understanding of how mesodermal tissue is formed, has been limited by the absence of specific and reliable markers of early mesoderm commitment. We report that mesoderm commitment from human embryonic stem cells (hESC) is initiated by Epithelial to Mesenchymal transition (EMT) as shown by gene expression profiling and by reciprocal changes in expression of the cell surface proteins, EpCAM/CD326 and NCAM/CD56. Molecular and functional assays reveal that CD326negCD56+ cells, generated from hESC in the presence of activin A, BMP4, VEGF and FGF2, represent a novel, multi-potent mesoderm-committed progenitor population. CD326negCD56+ progenitors are unique in their ability to generate all mesodermal lineages including hematopoietic, endothelial, mesenchymal (bone, cartilage, fat, fibroblast), smooth muscle and cardiomyocytes, while lacking the pluripotency of hESC. CD326negCD56+ cells are the precursors of previously reported, more lineage-restricted mesodermal progenitors. These findings present a novel approach to study how germ layer specification is regulated, and offer a unique target for tissue engineering. We used microarrays to compare gene expression profile of early mesodermal progenitors with undifferentiated hESC (H9 line). Mesoderm induction from hESC was initiatiated with combination of morphogens and growth factors including activin A, bone morphogenic protein 4, basic fibroblast growth factor and vascular endothelial growth factor. Proposed mesodermal progenitor population was isolated by FACS on day 3.5 of culture based on the presence of CD56 expression and the absenbce of CD326 expression.

Project description:Bone marrow stromal cells (BMSCs) were isolated from the femora and tibiae of irtTA-GBD*-TAg transgenic mice. Using cellular cloning we established skeletal progenitors with distinct differentiation properties and analysed their transcriptome. Unipotent osteogenic and adipogenic cells expressed specific transcriptional programs whereas bipotent clones combined expression of those genes and did not show a unique signature.
