【摘要】　目的　探討同種異基因骨髓間充質干細胞（bone mesenchamal stem cells，BMSC）靜脈輸注對大鼠到小鼠胰島移植物的功能保護和小鼠糖尿病狀態改善。　方法　全骨髓培養法獲得C57BL/6小鼠BMSC。不連續梯度離心法分離純化Sprague-Dawley（SD）大鼠胰島，將300胰島當量的胰島單獨或與BMSC聯合移植入鏈脲菌素誘導的糖尿病BALB/c小鼠腎包膜下，并通過尾靜脈在移植后0、3和5 d注射CM-DiI標記的BMSC 5×105/只，對照組給于磷酸鹽緩沖溶液。移植后監測血糖，第9天處死小鼠，取肝、脾、胸腺、淋巴結和移植胰島的腎臟，冰凍切片，熒光顯微鏡觀察CM-DiI標記細胞的組織分布；免疫熒光法觀察移植物中胰島素和胰高血糖素表達，評價胰島的功能。　結果　 BMSC靜脈輸注后主要分布于胸腺，其次是脾臟和淋巴結，腎和肝組織中未觀察到BMSC；BMSC聯合胰島移植組血糖控制水平優于其他組，且在第7天的口服糖耐量實驗優于單純胰島移植組。　結論　與胰島聯合移植的BMSC對受者免疫器官和組織有明顯的趨向性，且對胰島細胞的體內存活有一定保護作用。
【Abstract】　Objective　 To research on the protection function by the allogeneic rat bone mesenchymal stem cells (BMSC) on rat to mouse islet transplantation and the improvement of diabetic state in mouse. 　Methods　 BMSC were prepared from C57BL/6 mouse bone marrow cells and identified by flow cytometry (FCM). Islets were isolated from Sprague-Dawley (SD) rats with Ficoll discontinuous centrifugation. CM-DiI labeled BMSC at 5×105 for one mouse were intravenously infused into STZ induced diabetic BALB/c mice after rat to mouse islet transplantation at day 0, 3 and 5. Mice with PBS intravenously infused after islet transplantation were set as the negative controls. Blood glucose was monitored every day at the first 3 days after transplantation, and then monitored every two days. At day 9 after transplantation, spleen, thymus, lymph nods, liver and islets recipient kidney were harvested. Ice slices were prepared and CM-DiI labeled cells were investigated with fluorescence microscope. 　Results　 CM-DiI-labeled BMSC were mainly distributed in thymus followed by spleen and lymph nodes. In liver and kidney, there was no red fluorescence observed. The blood sugar control for combined BMSC infusion group was superior to other groups, and the control level of islet combined BMSC infusion group were better than single islet transplantation group in OGTT at day 7. 　Conclusion　 Allogeneic BMSC can sustain the insulin secretion of islets in vivo and tend to distribute in immune organs or adenoid tissues after infusion.
