Dimethyloxalylglycine (DMOG) has been found to stimulate osteogenesis and angiogenesis of stem cells, promoting neo-angiogenesis in bone tissue regeneration. In this review, we conducted a comprehensive search of the literature to investigate the effects of DMOG on osteogenesis and bone regeneration. We screened the studies based on specific inclusion criteria and extracted relevant information from both in vitro and in vivo experiments. The risk of bias in animal studies was evaluated using the SYRCLE tool. Out of the 174 studies retrieved, 34 studies met the inclusion criteria (34 studies were analyzed in vitro and 20 studies were analyzed in vivo). The findings of the included studies revealed that DMOG stimulated stem cells' differentiation toward osteogenic, angiogenic, and chondrogenic lineages, leading to vascularized bone and cartilage regeneration. Addtionally, DMOG demonstrated therapeutic effects on bone loss caused by bone-related diseases. However, the culture environment in vitro is notably distinct from that in vivo, and the animal models used in vivo experiments differ significantly from humans. In summary, DMOG has the ability to enhance the osteogenic and angiogenic differentiation potential of stem cells, thereby improving bone regeneration in cases of bone defects. This highlights DMOG as a potential focus for research in the field of bone tissue regeneration engineering.
二甲基草酰甘氨酸(DMOG)已被发现可刺激干细胞的成骨作用和血管生成作用,促进骨组织再生中的新血管生成。在本综述中,我们对文献进行了全面检索,以研究 DMOG 对成骨作用和骨再生的影响。我们根据具体的纳入标准筛选研究,并从体内和体外实验中提取相关信息。使用 SYRCLE 工具评估动物研究的偏倚风险。从检索到的 174 项研究中,有 34 项研究符合纳入标准(34 项研究在体外进行分析,20 项研究在体内进行分析)。纳入研究的结果表明,DMOG 刺激干细胞向成骨、血管生成和软骨生成谱系分化,导致血管化骨和软骨再生。此外,DMOG 对骨相关疾病引起的骨丢失具有治疗作用。然而,体外培养环境与体内明显不同,体内实验中使用的动物模型与人也有很大差异。总之,DMOG 能够增强干细胞的成骨和成血管分化潜能,从而改善骨缺损情况下的骨再生。这突显了 DMOG 作为骨组织再生工程领域研究的一个潜在焦点。
