Bone marrow stromal cells influence hematopoiesis through cell-cell interaction and release of hematopoietic growth factors. Macrophage colony-stimulating factor (M-CSF) is constitutively produced by several murine and human stromal cell lines and is induced by inflammatory mediators such as interleukin-1 alpha or tumor necrosis factor-alpha (TNF-alpha) in a variety of mesenchymal cells. Other ...
The CXCR4 chemokine receptor has been shown to respond to the C-X-C chemokine stromal-derived factor (SDF-1) and has recently been shown to be an important coreceptor for HIV-1 infection. In the present paper we have tested a number of human lymphocyte cell lines, including Jurkat, HUT78, CEM, and Sup-T1 for the presence of CXCR4 receptors. We found that these T cell lines bind SDF-1alpha and S...
Age is a significant risk factor for the development of cancer. However, the mechanisms that drive age-related increases in cancer remain poorly understood. To determine if senescent stromal cells influence tumorigenesis, we develop a mouse model that mimics the aged skin microenvironment. Using this model, here we find that senescent stromal cells are sufficient to drive localized increases in...
