Project description:In vitro expansion of endothelial progenitor cells (EPCs) remains a challenge in stem cell research and its application. We hypothesize that high density culture is able to expansion EPCs from bone marrow by mimicking cell-cell interactions of the bone marrow niche. To test the hypothesis, rat bone marrow cells were either cultured in high density by seeding or cultured in regular density. Flow cytometric analyses of the cells cultured for 15 days showed that high density cells exhibited smaller cell size and higher levels of marker expression related to EPCs when compared to regular density cultured cells. Global gene expression pattern difference between the high density and the regular density cultured cells was analyzed by a microarray assay.

Global gene expression pattern difference between the high density and the regular density cultured cells was analyzed by a microarray assay. Gene expression in rat bone marrow cells was measured at 15 days after high density culture or regular density cluture. 2 independent experiments were performed using different high density(HD) cultured cells for each experiment and bone marrow cells in regular density(RD) were used as a control.

Project description:Rat somatic lung cell had different gene expression level compared with that of the adult cells including rat bone marrow cells(BMC) and rat primary ear fibroblasts(PEF). This difference gave the rat somatic lung cell unique characteristics which could then be compared with the rat iPS cells by genes comparison to show the gene expression difference between rat somatic lung cells and rat iPS cells.

Project description:During aging, senescent cells accumulate in bone marrow and secrete the dysfunctional factors, termed senescence associated secretory phenotype (SASP), which is implied to regulate bone metabolism. To identify the key SASP factors in bone marrow that influence skeletal aging, we analyzed the dysregulated factors in the bone marrow supernatant from young and aged rat through mass spectrometry. In another hand, BMSCs treated with rGCA, transfection of siRNA-Plxnb2 or controls were subjected to global quantitative phosphoproteomic analysis.

Project description:We cultured bone marrow derived dendritic cells from WT and CD11c KO mice. Then, a group of bone marrow dendritic cells were stimulated with LPS overnight. We obtained bone marrow derived dendritic cells with or without LPS stimulation and analyzed proteomics profiles.

Project description:Bone marrow cells were isolated, primed with M-CSF (M-BMDM) or GM-CSF (GM-BMDM) and cultured for 7 days. The proteomic difference between GM-BMDM and M-BMDM were analyzed to describe the phenotye and function of two types of macrophages.

Project description:Object: To study the difference of gene expression pattern of bone marrow mesenchymal stem cells (BMMSCs) between psoriatic patients, normal adults and aborted fetuses, and then to explore the influence of bone marrow mesenchymal stem cells to immune system. Methods: Bone marrow mononuclear cells (BMMNC) of 7 psoriatic patients, 4 healthy volunteers and 3 aborted fetuses were isolated and the BMMSCs were cultured using the adherent method. Gene expression of 14 samples was detected by gene microarray and the different expressed genes were analysised by SAM software. Results: 654 differentially expressed genes (66 up regulated, 588 down regulated) were detected between the psoriatic patients and normal adults, which were enriched in immune response, chemotaxis and cell adhesion etc. 2020 differentially expressed genes (888 up regulated, 1132 down regulated) were detected between the aborted fetuses and normal adults. These genes were enriched in cell cycle, cell division, immune response and MHC class II antigen etc. Conclusion: The gene expression pattern such as immune response, chemotaxis was aberrant in psoriatic BMMNCs, which was consistent with aborted fetuses in some immune related genes. Bone marrow mononuclear cells (BMMNC) of 7 psoriatic patients, 4 healthy volunteers and 3 aborted fetuses were isolated and the BMMSCs were cultured using the adherent method. Gene expression of 14 samples was detected by gene microarray and the different expressed genes were analyzed by SAM software.

Project description:Synovial and bone marrow mesenchymal stem cells after intradiscally injection show regenerative effects of nucleus pulposus. Microarray analyses of rats were performed to investigate the closeness of the gene profiles between the nucleus pulposus cells and the synovial or bone marrow mesenchymal stem cells. To investigate interaction between synovial mesenchymal stem cells and nucleus pulposus cells, human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured, and species specific microarray were performed. Synovium of knee joints, bone marrow and nucleus pulposus were harvested from rat or human, and cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. To compare the gene profiles each other, isolated cells were mono-cultured respectively, and human synovial mesenchymal stem cells and rat nucleus pulposus cells were co-cultured.
