Abstract

Objective

Biodegradable collagen membranes are widely used in guided bone regeneration. This study evaluated the effect of enamel matrix proteins (Emdogain®) combined with two collagen membranes (Bio-Gide® or Collprotect®) on osteoblastic cell cultures.

Methods

Human osteoblastic cells were cultured on Bio-Gide® or Collprotect® membranes coated with Emdogain® or left uncoated. The assessed parameters included amelogenin quantification at 1 h, 12 h, 1 day, 3 days, and 7 days; cell morphology at 1 day; cell proliferation at 1, 2, and 3 days; gene expression of COL1A1, IBSP, SPP1, and BGLAP at 1 day; Collagen type I quantification at 3 and 7 days; alkaline phosphatase (ALP) activity at 3 and 7 days; and mineralization at 14 days. Data were analyzed using two-way analysis of variance or the Kruskal-Wallis test.

Results

Higher amelogenin levels were detected in Bio-Gide® cultures than in Collprotect® cultures after 3 and 7 days. Cells adhered and spread in all experimental groups. Cell proliferation was higher in Bio-Gide® cultures after 3 days (p < 0.05). Gene expression of COL1A1, IBSP, and SPP1 was greater in Bio-Gide® cultures with Emdogain® after 1 day. There was higher collagen type I secretion by cultures grown on collagen membranes coated with Emdogain®, particularly on Bio-Gide® cultures at 7 days. ALP activity was also higher in Bio-Gide® cultures at 7 days (p < 0.05). Greater mineralization was detected in cultures grown on Bio-Gide® with Emdogain® (p < 0.05).

Conclusion

Combining collagen membranes, particularly Bio-Gide®, with enamel matrix proteins promotes osteogenesis in vitro, potentially advancing bone tissue regeneration and preservation methods.

牙釉质基质蛋白结合胶原膜对成骨细胞培养的影响。
目的:生物可降解胶原膜在骨引导再生中的广泛应用。本研究评估了牙釉质基质蛋白(Emdogain®)联合两种胶原膜(Bio-Gide®或Collprotect®)对成骨细胞培养的影响。方法:将人成骨细胞培养在包被Emdogain或未包被的Bio-Gide®或Collprotect®膜上。评估参数包括:1 h、12 h、1 d、3 d和7 d的淀粉原蛋白定量;第1天细胞形态;1、2、3天细胞增殖;1 d时COL1A1、IBSP、SPP1、BGLAP基因表达;第3天和第7天进行I型胶原定量;3、7 d碱性磷酸酶(ALP)活性;矿化在14天。数据分析采用双向方差分析或Kruskal-Wallis检验。结果:在3和7天后,Bio-Gide®培养物中检测到的淀粉原蛋白水平高于Collprotect®培养物。各实验组细胞均有粘附和扩散。结论:将胶原膜,特别是Bio-Gide®与牙釉质基质蛋白结合可以促进体外成骨,潜在地促进骨组织再生和保存方法。
