摘要: 为了验证犬脂肪间充质干细胞(adipose-derived stem cells,ASCs)临床应用的安全性,本试验取第4代犬ASCs,显微镜下观察细胞形态,并进行成脂、成骨及成软骨诱导分化和细胞表面标志蛋白分析。结果显示ASCs呈纺锤体状贴壁生长,形态均匀一致,体外ASCs可分化为脂肪细胞、骨细胞、软骨细胞。犬ASCs表达标记蛋白CD29、CD44、CD105和CD166,不表达CD34和CD45,符合典型的脂肪间充质干细胞特征。犬ASCs以1×106/kg进行静脉移植,速度10 mL/(kg·h),注射过程中未见任何不良反应。长期观察3个月,未见明显相关并发症。与移植前相比,血液检查发现白细胞数、中性粒细胞数、单核细胞数、嗜酸性粒细胞数、红细胞数、血红蛋白和血小板数等均无显著差异(P>0.05);血清生化检查发现白蛋白、ALTAKP等肝指标差异不显著(P>0.05),肾指标肌酐、血清尿素、血磷和血钙差异不显著(P>0.05),胰腺相关指标血糖和血清淀粉酶均无显著差异(P>0.05),心肌损伤指标肌酸激酶和血脂指标胆固醇,在细胞移植前后也无显著差异 (P>0.05)。本试验结果表明了犬ASCs应用的临床安全性,为细胞移植治疗奠定了基础。

Abstract: In order to verify the safety of clinical application of canine adipose derived stem cells (ASCs), the fourth generation of canine ASCs were selected in this experiment, and the cell morphology was observed under the microscope, and adipogenesis, osteogenesis and chondrogenesis were induced and differentiated, and cell surface marker proteins were analyzed. The results showed that ASCs grew as spindle-like adherent cells with uniform morphology. ASCs could differentiate into adipocytes, osteocytes and chondrocytes in vitro. Canine ASCs express marker proteins CD29, CD44, CD105 and CD166, but do not express CD34 and CD45, which conforms to the typical characteristics of adipose mesenchymal stem cells. Canine ASCs with 1×106/kg vein transplantation was performed at a speed of 10 mL/(kg·h). No adverse reaction was found during the injection. Long term observation for 3 months showed no obvious complications. Compared with that before transplantation, the number of white blood cells, neutrophils, monocytes, eosinophils, red blood cells, hemoglobin and platelets showed no significant difference(P>0.05); Serum biochemical examination showed that there were no significant differences in liver indicators such as albumin, ALT, AKPP>0.05), renal indicators such as creatinine, serum urea, blood phosphorus and blood calcium(P>0.05), pancreatic related indicators such as blood glucose and serum amylase(P>0.05), myocardial injury indicators such as creatine kinase and blood lipid indicators such as cholesterol before and after cell transplantation(P>0.05). The results of this study showed the clinical safety of ASCs in dogs and laid a foundation for cell transplantation therapy.
