摘要:

文题释义:
珍珠粉:是一种优良的天然生物材料,含有碳酸钙、蛋白质、活性肽、氨基酸和多种微量元素,具有良好的生物相容性和生物活性。珍珠粉可促进成纤维细胞增殖分化及组织中胶原蛋白的产生,可以激活超氧化物歧化酶来清除过氧化自由基,具有促进软组织修复与再生的作用。
细胞凋亡:是机体重要的自我调节机制,能够清除潜在的危险细胞或不再需要的细胞,是细胞早期发育和病理生理条件下维持形态发生稳态所必需的基本过程,对胚胎的发育、组织细胞的稳定、调节机体的免疫反应等正常生理进程起着重要作用,并具有潜在的治疗意义。Bcl-2和Bax是关键的凋亡调控蛋白,Bcl-2具有抗凋亡作用,而Bax则有促进凋亡作用。

背景:珍珠粉富含多种活性成分,可促进成纤维细胞增殖及迁移,从而促进创面愈合和皮肤组织再生。然而,纳米珍珠粉水溶性基质对小鼠成纤维细胞L929增殖、迁移及凋亡的影响尚未报道。
目的:探究纳米珍珠粉水溶性基质对小鼠成纤维细胞L929增殖、迁移及凋亡的影响。
方法:将第6代L929细胞分5组培养:阴性对照组不加入任何材料,阳性对照组加入PBS,水溶性基质低、中、高质量浓度组分别加入10,25,40 μg/mL的纳米珍珠粉水溶性基质,采用MTT法检测细胞增殖,Transwell小室实验检测细胞迁移能力,流式细胞术检测细胞凋亡率,Western blot检测凋亡相关蛋白Bax、Bcl-2和Caspase-1的表达。
结果与结论:①MTT检测与Transwell小室实验结果显示,纳米珍珠粉水溶性基质可促进L929细胞的增殖与迁移,并且具有浓度依赖性;②流式细胞术与Western blot检测结果显示,纳米珍珠粉水溶性基质可降低L929细胞凋亡率及Bax、Caspase-1的蛋白表达,提高Bcl-2蛋白的表达,并且具有浓度依赖性;③结果表明,纳米珍珠粉水溶性基质在高质量浓度的处理下,可以抑制细胞的凋亡。结果表明,纳米珍珠粉水溶性基质可促进成纤维细胞的增殖、迁移,抑制成纤维细胞的凋亡。

Abstract: BACKGROUND: Pearl powder is rich in many active ingredients, which can promote the proliferation and migration of fibroblasts, thus promoting wound healing and skin tissue regeneration. However, the effect of nano-pearl powder water-soluble matrix on proliferation, migration and apoptosis of mouse fibroblasts L929 has not been reported.
OBJECTIVE: To investigate the effect of nano-pearl powder water-soluble matrix on the proliferation, migration and apoptosis of mouse fibroblasts L929. 
METHODS: Passage 6 L929 cells were divided into five groups. The negative control group did not add any material; the positive control group added PBS, and the low, medium and high mass concentration groups of water-soluble matrix were added with 10, 25 and 40 μg/mL of nano-pearl powder water-soluble matrix, respectively. The proliferation of L929 cells was detected by MTT assay. The migration ability of L929 cells was detected by Transwell. The apoptosis rate of L929 cells was detected by flow cytometry. The expressions of apoptosis-related proteins Bax, Bcl-2, and Caspase-1 were detected by western blot assay.
RESULTS AND CONCLUSION: (1) The results of MTT assay and Transwell chamber experiment showed that the water-soluble matrix of nano-pearl powder could promote the proliferation and migration of L929 cells, and it was concentration dependent. (2) Flow cytometry and western blot assay results showed that the water-soluble matrix of nano-pearl powder could reduce the apoptosis rate of L929 cells and the protein expression of Bax and Caspase-1, and increase the expression of Bcl-2 protein, and it was concentration dependent. (3) These findings exhibited that the water-soluble matrix of nano-pearl powder could inhibit cell apoptosis under high mass concentration treatment. The results show that the water-soluble matrix of nano-pearl powder can promote the proliferation and migration of fibroblasts and inhibit the apoptosis of fibroblasts.
