Abstract

Anti-inflammatory effects of murine fetal liver (FL) cells were studied using BALB/c mouse contact hypersensitivity (paw edema) model. Paw weight differences, lymphatic organ weights, hematological and histological indices as well as proinflammatory (TNF-alpha) and anti-inflammatory (IL-10) cytokine levels in sera were evaluated. Immunophenotyping revealed that both murine FL homogenate cells (HC) and FL hematopoietic stem cells (HSC) express CD117 and CD38 surface markers. Single doses of 1x10(6) cells/mouse and 2x10(6) cells/mouse of FL HC as well as of FL HSC, when used separately, all statistically significantly (p<0.05) inhibited paw edema, but the lower dose was more effective and giving results similar to that of prednisolone. Either dose of FL HC or FL HSC studied had no significant influence on lymphatic organ weights; no significant changes were also observed in blood indices. The data of cytokine studies showed that TNF-alpha concentration in sera of mice treated with either FL HC or FL HSC at a dose of 1x10(6) cells/mouse was statistically significantly (p<0.001) lower than that of the control mice. A concentration of IL-10 was statistically significantly higher (p<0.01) in mice treated with a dose of 1x10(6) cells/...Continue Reading

Adult Stem Cells

Adult stem cells reside in unique niches that provide vital cues for their survival, self-renewal, and differentiation. They hold great promise for use in tissue repair and regeneration as a novel therapeutic strategies. Here is the latest research.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
