Cardiac fibroblasts constitute greater than 90% of non-myocyte cells in the heart. Because they are responsible for synthesis of components of the extracellular matrix, growth factors and cytokines in the myocardium, they play an important role in normal and pathologic performance of the heart. An understanding of their biology requires in depth studies in a stable and reliable system in which the biological responses of cardiac fibroblasts to various stimuli can be determined. With the exception of few, all studies have been performed on cardiac fibroblasts obtained from rodent hearts. We present a method for isolation and subsequent culture of viable cardiac fibroblasts from ventricular tissue of adult human. This method allows rapid and reliable isolation and subsequent culture of cardiac fibroblasts from adult heart tissue without the need for cumbersome isolation techniques and complex nutrient-enriched and hormone-supplemented culture media for maintenance. 相似文献

MAb anti-Leu-13 reacts with a 16-kDa-interferon-responsive lymphocyte-endothelial cell surface antigen and has been demonstrated to induce lymphocyte aggregation by an undefined adhesion pathway. While anti-Leu-13 inhibits proliferation triggered by CD3 antibodies it was found to consistently augment proliferation induced by a pair of CD2 antibodies at suboptimally mitogenic concentrations. The latter mechanism of T cell activation may represent an antigen-nonspecific activation pathway requiring extensive cell-cell interaction. Proliferation induced via the CD2 pathway was very sensitive to the presence of monocytes whose inhibitory effect was reversed by indomethacin. While the potent inhibitory effect of PGE2 on proliferation induced via the CD2 pathway was weakly antagonized by anti-Leu-13, the combined effects of anti-Leu-13 and PGE2 on the CD3 pathway were additive and very inhibitory. The possibility that the Leu-13 signal reflects a mechanism by which a monocyte/macrophage-sensitive T cell activation pathway might be selectively amplified in vivo is discussed. 相似文献
