Abstract:
BACKGROUND AIMS:Recent evidence has suggested that transplanted bone marrow (BM)-derived mesenchymal stromal cells (MSC) are able to engraft and repair non-hematopoietic tissues successfully, including central nervous system, renal, pulmonary and skin tissue, and may possibly contribute to tissue regeneration. We examined the cytoprotective effect of BM MSC on co-cultured, isolated pancreatic islets. METHODS:Pancreatic islets and MSC isolated from Lewis rats were divided into four experimental groups: (a) islets cultured alone (islet control); (b) islets cultured in direct contact with MSC (IM-C); (c) islets co-cultured with MSC in a Transwell system, which allows indirect cell contact through diffusible media components (IM-I); and (d) MSC cultured alone (MSC control). The survival and function of islets were measured morphologically and by analyzing insulin secretion in response to glucose challenge. Cytokine profiles were determined using a cytokine array and enzyme-linked immunosorbent assays. RESULTS:Islets contact-cultured with MSC (IM-C) showed sustained survival and retention of glucose-induced insulin secretory function. In addition, the levels of monocyte chemoattractant protein-1 (MCP-1) and tumor necrosis factor-α (TNF-α) were decreased, and tissue inhibitor of metalloproteinases-1 (TIMP-1) and vascular endothelial growth factor (VEGF) levels were increased at 4 weeks in both the IM-C and IM-I groups. CONCLUSIONS:These results indicate that contact co-culture is a major factor that contributes to islet survival, maintenance of cell morphology and insulin function. There might also be a synergic effect resulting from the regulation of inflammatory cytokine production. We propose that BM MSC are suitable for generating a microenvironment favorable for the repair and longevity of pancreatic islets.
