摘要:

背景:目前传统骨髓间充质干细胞的培养方法是应用异种血清为培养基,但其存在种间疾病传播、潜在免疫排斥反应甚至是伦理学争议等问题;且与卫生部公布的《组织工程化组织移植治疗技术管理规范》的要求相违背。自体富血小板血浆是生物自体的全血提取物,内含多种且含量丰富的生长因子。

目的:使用自体富血小板血浆替代传统异种血清,探讨其对兔骨髓间充质干细胞诱导分化为成骨细胞的影响,
方法:从兔髂后上棘穿刺抽出8 mL骨髓并加肝素抗凝,密度梯度离心富集骨髓间充质干细胞,分为自体富血小板血浆组、胎牛血清组,分别加入含10%自体富血小板血浆、体积分数10%胎牛血清。在传至4代时将自体富血小板血浆组和胎牛血清组细胞各自分为实验组和对照组,实验组对培养及成分进行改变;对照组培养基不变。通过生长曲线测定各代细胞的增殖情况;通过对各组细胞进行碱性磷酸酶活性测定,判断其成骨分化状况。
结果与结论:骨髓间充质干细胞生长曲线可见各代细胞增殖良好。对第4代各组细胞进行碱性磷酸酶活性检测,培养第12天,第4代自体富血小板血浆实验组及胎牛血清实验组的碱性磷酸酶活性均显著高于其相应对照组;自体富血小板血浆组对照组、实验组碱性磷酸酶活性显著高于胎牛血清组的对照组、实验组,差异有显著性意义(P < 0.01)。提示使用自体富血小板血浆替代异种血清培养骨髓间充质干细胞是一种安全可靠、操作简单、纯度活性高的诱导骨髓间充质干细胞的成骨分化方法。

Abstract:

BACKGROUND: At present, heterologous serum as a medium is a common method for culture of bone marrow mesenchymal stem cells, but it is limited by the disease transmission between species, the potential immune rejection and even controversial ethic issues. This method is also contrary to the requirements of the Ministry of Health. Autologous platelet-rich plasma is a kind of whole blood extract, containing a variety of growth factors.

OBJECTIVE: To explore the osteogenic differentiation of rabbit bone marrow mesenchymal stem cells cultured in autologous platelet rich plasma alternative to traditional heterogeneous serum-free culture.
METHODS: 8 mL bone marrow from the rabbit iliac crest was extracted and anti-coagulated with heparin, and then bone marrow mesenchymal stem cells were isolated using density gradient centrifugation. The cells were divided into autologous platelet rich plasma group (10% autologous platelet rich plasma) and fetal bovine serum group (10% fetal bovine serum). At the passage 4, the cells in the two groups were respectively subdivided into experimental and control groups. Experimental groups were subjected to osteogenic induction, while no change was done in the control groups. Cell proliferation was determined by using growth curves; the activity of alkaline phosphatase was detected to adjust the osteogenic differentiation of cells in different groups.
RESULTS AND CONCLUSION: Bone marrow mesenchymal stem cells at different generations all showed good proliferation. At 12 days of autologous platelet rich plasma culture, the activity of alkaline phosphatase in the passage 4 cells in the experimental group was significantly higher than that in the control group; while the activity of alkaline phosphatase in the autologous platelet rich plasma group was significantly higher than that in the fetal bovine serum group (P < 0.01). These findings indicate that autologous platelet rich plasma as a substitute of xenogeneic serum for culture of bone marrow mesenchymal stem cells is a method characterized as safe and reliable, simple operation, high-purity active induction.
