Fibrous Tissues

It is well known that various fibrous tissue such as tendons and ligaments functionally adapt to dynamic and static loads. Although a variety of biomechanical studies have been done to deterimine the mechanism of remodeling in fibrous tissues, it was difficult to obtain detailed information because of complicated condstitution of the tissues. We have developed a stem cell-based self-assembled tissue (scSAT) [1] for tissue engineering. Since the scSAT is consisted of synovium-derived mesenchyaml stem cells and their native extracellular matrix, it is a good experimental model to determine the process of remodeling of fibrous tisues. However, the response of shear stress to the scSAT specimen has not been determined so far, although such data are important for understanding of soft tissue remodeling and for improvement of regenerative medicine. Therefore, the present study was performed to determine the effect of shear stress on the extracellular matrix production of synovium-derived cells including mesenchymal stem cells.

The mechanical stimulation from extracellular matrix could regulate physiological behavior of cells through the mechanism of mechanotransduction. Previous researches had shown that apoptosis could be regulated by the size of the cell adhesion area.However, the regulation of cell apoptosis by different adhesion shape with the same area is still unclear. This workfocused on the regulation of apoptosis for bone marrow mesenchymal stem cells (MSCs) by different circularity and area of adhesion geometry. We manufactured micro-pattern surface which was suitable for adhesion of MSCs by the technique of micro-contact printing. Three typesof geometry for individual is land of micro-pattern were designed. We adopted terminal-deoxynucleoitidyl transfer as emediated nick end labeling (TUNEL) method to detectcell apoptosis. This research shows that the adhesion geometry which has smaller area and greater circularity will promote apoptosis of MSCs. This indicates that MSCsmay prefer to live on the surface without any restrict. Ourstudies focused on the significantly important problem about interaction between extracellular matrix and physiological behavior of mesenchymal stem cells.

Acute Myeloid

Acute myeloid leukemia (AML) is an aggressive bone marrow malignancy, and non-leukemic stromal cells (including mesenchymal stem cells, MSCs) are involved in leukemogenesis and show AML-supporting effects. We investigated how constitutive extracellular mediator release by primary human AML cells alters proteomic profiles of normal bone marrow MSCs. An average of 6814 proteins (range 6493−6918 proteins) were quantified for 41 MSC cultures supplemented with AML-cell conditioned medium, whereas an average of 6715 proteins (range 6703−6722) were quantified for untreated control MSCs. The AML effect on global MSC proteomic profiles varied between patients. Hierarchical clustering analysis identified 10 patients (5/10 secondary AML) showing more extensive AML-effects on the MSC proteome, whereas the other 31 patients clustered together with the untreated control MSCs and showed less extensive AML-induced effects. These two patient subsets differed especially with regard to MSC levels of extracellular matrix and mitochondrial/metabolic regulatory proteins. Less than 10% of MSC proteins were significantly altered by the exposure to AML-conditioned media; 301 proteins could only be quantified after exposure to conditioned medium and 201 additional proteins were significantly altered compared with the levels in control samples (153 increased, 48 decreased). The AML-modulated MSC proteins formed several interacting networks mainly reflecting intracellular organellar structure/trafficking but also extracellular matrix/cytokine signaling, and a single small network reflecting altered DNA replication. Our results suggest that targeting of intracellular trafficking and/or intercellular communication is a possible therapeutic strategy in AML.
