The aim of this study was to establish a tree shrew metabolic syndrome model and demonstrate the utility of MSCs in treating metabolic syndrome. We used tree shrew umbilical cord mesenchymal stem cell (TS-UC-MSC) transplantation for the treatment of metabolic syndrome to demonstrate the clinical application of these stem cells and to provide a theoretical basis and reference methods for this treatment. Tree shrew metabolic syndrome model showed significant insulin resistance, high blood sugar, lipid metabolism disorders, and hypertension, consistent with the diagnostic criteria. TS-UC-MSC transplantation at 16 weeks significantly reduced blood sugar and lipid levels, improved insulin resistance and the regulation of insulin secretion, and reduced the expression levels of the pro-inflammatory cytokines IL-1 and IL-6 (P < 0.05). The transplanted TS-UC-MSCs targeted the liver, kidney and pancreas; reduced liver cell degeneration, necrosis, and inflammatory exudation; mitigated bleeding congestion and inflammatory cell infiltration in the kidney; and reduced islet cell degeneration and necrosis. We successfully developed a tree shrew metabolic syndrome model and showed that MSC migrate in diseased organs and can attenuate metabolic syndrome severity in a tree shrew model. © 2016 Springer Science+Business Media Dordrecht Source

We previously found that chicken egg white extract could promote cell survival and proliferation. In the present study, we further separated this extract into its components to identify those primarily responsible for promoting cell proliferation. Components of differing molecular weight were separated from chicken egg white extract by ultrafiltration and 293T cell cultures were supplemented with various concentrations. The effects on cell proliferation were subsequently determined by a CellTiter 96 Aqueous One Solution Cell Proliferation Assay kit (Promega). We demonstrate that components from chicken egg white smaller than 3 kDa in size are able to function as active ingredients promoting cellular proliferation. This discovery may identify a new and convenient additive for cell culture media to promote cell growth and proliferation. © 2015 Springer Science+Business Media Dordrecht Source
