摘要 间充质干细胞(MSCs)是主要存在于骨髓中的非造血性干细胞,可以从广泛的组织来源中提取,并可分化为多种细胞,如:成骨细胞,成软骨细胞,成脂肪细胞,神经样细胞,血管内皮细胞等。在体外培养MSCs过程中,胎牛血清和生长因子的选择,以及多能分化诱导控制等,对MSCs的体外繁殖和分化至关重要。大量的临床研究证明,经体外分化繁殖的MSCs,在疾病的再生医疗和组织工程领域有很大的应用潜能。牙周韧带来源的间充质干细胞(PDL-MSCs)经体外培养,贴壁,伸展性良好,将它移植于生物相容性支架材料中,具有高度伸展性和分化为成骨细胞的能力。因此,应用PDL-MSCs和骨髓来源的骨髓-MSCs制成的有效的移植生物材料,可用于牙周再生中的骨组织工程治疗。
