摘要:

背景:间充质干细胞移植可通过多种调节机制促进皮肤创伤修复,抑制瘢痕形成,目前多数学者认为间充质干细胞分泌的生物活性因子起主要作用。
目的:观察骨髓间充质干细胞条件培养液对增生性瘢痕成纤维细胞增殖能力及胶原合成的影响。
方法:分离培养人骨髓间充质干细胞和增生性瘢痕成纤维细胞,制备骨髓间充质干细胞条件培养液。将12,24,48 h收集的条件培养液孵育体外培养的增生性瘢痕成纤维细胞24 h,并与空白对照组比较,采用CCK-8实验检测增生性瘢痕成纤维细胞的增殖活性,Real-time PCR检测增生性瘢痕成纤维细胞中Ⅰ型和Ⅲ型胶原的表达。
结果与结论:与空白对照组相比较,在24 h和48 h收集的骨髓间充质干细胞条件培养液对增生性瘢痕成纤维细胞的增殖具有明显的抑制作用(P < 0.01),对其胶原的合成也具有显著的抑制作用(P < 0. 01)。结果表明骨髓间充质干细胞条件培养液可通过分泌抗纤维化的生物活性因子抑制增生性瘢痕成纤维细胞的增殖和胶原产生,为细胞疗法策略减轻瘢痕提供了新的理论支持。

Abstract:

BACKGROUND: Mesenchymal stem cell transplantation promoted skin repair in trauma via various regulatory mechanisms and inhibited scar formation. At present, many scholars believed that bioactive factors secreted by mesenchymal stem cells played an important role.
OBJECTIVE: To investigate the effects of bone marrow mesenchymal stem cell conditioned medium on the proliferation and collagen synthesis of hypertrophic scar fibroblasts.
METHODS: Human bone marrow mesenchymal stem cells and hypertrophic scar fibroblasts were isolated and cultured, and bone marrow mesenchymal stem cell conditioned medium was prepared. Hypertrophic scar fibroblasts were cultured in vitro with 12, 24, and 48 hour-collected conditioned medium for 24 hours, which was compared with blank control group. The proliferation of cells was determined by CCK-8. Type I and type III collagen expression in hypertrophic scar fibroblasts was detected using real-time PCR.
RESULTS AND CONCLUSION: Compared with the blank control group, 24 and 48 hour-collected conditioned medium significantly inhibited the proliferation of hypertrophic scar fibroblasts (P < 0.01), and also suppressed collagen synthesis of hypertrophic scar fibroblasts (P < 0.01). Results suggested that bone marrow mesenchymal stem cell conditioned medium inhibited the proliferation and collagen synthesis of hypertrophic scar fibroblasts by secreting anti-fibrotic bioactive factors, which may provide new theoretical supports for cell therapy to reduce cutaneous scarring.
