Project description:The physiological niche of bone marrow is hypoxic. However, the artificial growth of bone marrow derived-mesenchymal stromal cells (MSC)s very often occurs in normoxia which may impact the protein expression with immunomodulatory properties. Thus, cell viability and respiration were assessed as well as the proteomic profile of MSCs and their EVs submitted to normoxia (21% O2) and hypoxia (1% O2) for 48 hours were evaluated. MSCs and EVs total protein were isolated for mass spectrometry.

Project description:Chronic inflammation leading to pro-inflammatory macrophage infiltration contributes to the pathogenesis of type 2 diabetes and subsequently the development of diabetic nephropathy. Mesenchymal stem cells (MSCs) possess unique immunomodulatory and cytoprotective properties making them an ideal candidate for therapeutic intervention We used microarrays to detail changes in the gene expression profile of monocytes isolated from type 2 diabetic patients with end-stage renal disease and non-diabetic control subjects following co-culture with MSCs. Control blood samples were obtained from 4 donors from the Australian Red Cross Blood Service. Blood was also obtained from 5 diabetic patients with end-stage renal disease receiving haemodialysis at the Monash Medial Centre. CD14+ monocytes were isolated from blood using microbeads and co-cultured for 48 hours with and without human bone marrow-derived MSCs using an in vitro transwell system. An Affymetrix GeneChip Human Gene 2.0 ST array was used.

Project description:To screen and identify key molecule regulating T2DM (Type 2 diabetes mellitus)-impaired bone regeneration, cellular osteogenic potential and mitochondrial function, and to elucidate the regulatory mechanisms of this molecule. Microarray analysis was performed to compare transcriptional profiles between bone marrow mesenchymal stem cells (BMMSCs) derived from normal rats (Wistar) and T2DM rats (GK). BMMSCs were transfected with overexpression plasmids targeting candidate molecule and small interfering RNA (siRNA) was used to silence candidate gene expression, then the osteogenic differentiation potential and mitochondrial function of BMMSCs were assessed. Microarray and qRT-PCR revealed significantly elevated expression of TGM2 in BMMSCs from T2DM rats compared to those from normal rats. TGM2 silencing suppressed osteogenic differentiation and mitochondrial function of BMMSCs, and TGM2 overexpression rescued osteogenic capacity. TGM2 serves as a critical regulator of osteogenic differentiation potential and mitochondrial function in BMMSCs derived from T2DM rats

Project description:Human bone marrow-derived marrow stromal cell (BM-MSC) and neurosphere (BM-neurosphere) transplantation shows limited efficacy as a therapeutic adjunct to surgical decompression in an implantable polymer-induced degenerative cervical myelopathy (DCM) model Degenerative cervical myelopathy (DCM) is a prevalent spinal cord disorder in the developed world. The study investigates the therapeutic potential of human bone marrow-derived mesenchymal stem cells (BM-MSC) and BM-neurospheres as adjunct therapies to surgical decompression in a polymer-induced DCM rat model. The study assessed locomotor function, blood-spinal cord barrier (BSCB) integrity, and cell engraftment. Results showed delayed locomotor recovery upon cervical decompression and limited efficacy of BM-MSCs and BM-neurospheres in improving outcomes under the experimental conditions.

Project description:Background: Mesenchymal stem cells (MSCs) have been widely used in the treatment of various inflammatory diseases. The inadequate understanding of MSCs and its heterogeneity can impact the immune environment maybe the cause of the good outcomes of MSCs-based therapy cannot be always achieved. Recently, stem cells from human exfoliated deciduous teeth (SHED) showed a great potential in inflammatory and autoimmune diseases due to its unique immunomodulation properties. However, the cellular heterogeneity and the corresponding immunomodulation functions of SHED remains unclear. Methods: In this study, we applied single-cell RNA sequencing (scRNA-seq) to analyze and performed bioinformatic analysis to clarify the variations immunomodulation functions of SHED subpopulations in different differentiation state. After the integration of public available databases, we analyzed the transcriptome and compared the difference of immunomodulation functions of MSCs from different tissues. Results: SHED in low differentiation state (S7) exhibited the powerful ability to recruit multiple types of immune cells, whereas SHED in relatively high differentiation state (S1) may hold strong ability to secret many factors with paracrine signaling capacity. Compared with human bone marrow derived mesenchymal stem cells (hBMSCs) or human umbilical cord-derived mesenchymal stem cells (hUCMSCs), SHED is stronger in immunomodulatory property, especially in recruitment of Th17, Th22 and Treg cells. Conclusion: SHED was a heterogeneous MSCs population with different differentiation states and immunomodulatory functions. SHED may have some advantages in treatment of inflammatory and autoimmune diseases. Our works provides some theoretical foundation for the SHED-based therapy in clinical applications.

Project description:We found that mesenchymal stem cells isolated from colonic tissue express significantly increased expression of Ptgs2 or cox-2 compared to that of mesenchymal stem cells isolated from the bone marrow, one of the most common tissues from which this cell type is derived. We hypothesized that the localization of these cells in the colon exposes them to specific environmental factors that induce and/or maintain increased constitutive levels of cox-2 uniquely in this cell type. In order to identify possible candidate molecules regulating cox-2 in these cells, we decided to compare the transcriptomes of colonic mesenchymal stem cells and bone marrow-derived mesenchymal stem cells.
