Abstract: Concentrated growth factors (CGF) belongs to the new generation of autologous platelet concentrates,containing high concentration growth factor,leukocyte,CD34+positive cells,platelet,fibrin network and anti-inflammatory factor and other bioactive substances. In this article, we summarize the development course of CGF,preparation methods, classification, component analysis and biological effect, and analyze the comparative study of CGF,PRP and PRF in existing literature.The application status and effect of CGF in stomatology, wound repair, cosmetic surgery and other fields were described, and the value of CGF as an ideal material in promoting tissue regeneration and repair and cosmetology and anti-aging was affirmed. Finally,some suggestions and prospects are put forward for the existing problems and prospects of CGF research and application.

自体血小板浓缩物是指通过一定的分离、浓缩、提取等技术,按照规范化的操作流程从人体自身血液获取的、经验证具有治疗或美容作用的血液浓缩制品(PRP、PRF及CGF等),将其注射到人体的特定部位或外用,用以促进局部组织修复、再生,从而达到年轻化、延缓衰老及修复重建的目的[1]。相关文献将自体血小板浓缩物分为三代,第一代为富血小板血浆(Platelet rich plasma,PRP),第二代为富血小板纤维蛋白(Platelet rich fibrin,PRF),第三代为浓缩生长因子(Concentrated growth factors,CGF)。

1  CGF的发展历程

血小板从最初被认为只参与凝血功能,到被发现具有分泌多种生长因子功能,经历了漫长的探索过程,1986年的诺贝尔生理学或医学奖共同授予Stanley Cohen与Rita Levi Montalcini,以表彰他们在发现生长因子方面的杰出贡献。正是基于血小板所具有的生物学特性,才促使了自体血小板浓缩物用于临床医疗的实践,并进一步形成了以PRP、PRF及CGF为代表的不同形式。……
