摘要：牙周疾病是一種常見的口腔疾病，其主要導(dǎo)致牙周組織的破壞和牙齒的喪失。干細胞治療成為牙周疾病的一種新興治療方法。本研究旨在探究液態(tài)濃縮生長因子對人牙周膜干細胞成骨能力的影響。通過對人牙周膜干細胞進行培養(yǎng)，加入不同濃度的液態(tài)濃縮生長因子，觀察其對干細胞的生長、增殖和成骨能力的影響。結(jié)果表明，不同濃度的液態(tài)濃縮生長因子對人牙周膜干細胞的成骨能力有顯著的影響。適當(dāng)?shù)臐舛纫簯B(tài)濃縮生長因子可以提高干細胞成骨能力，增加新骨生成率。本研究對引導(dǎo)牙周膜干細胞成骨治療提供理論基礎(chǔ)。

Inrecentyears,concentratedgrowthfactors(CGFs)havebeenusedasasourceofgrowthfactorsfortissueregeneration.CGFsarederivedfromthepatient'sownbloodandcontainahighconcentrationofgrowthfactors,includingplatelet-derivedgrowthfactor,transforminggrowthfactor-β,insulin-likegrowthfactor,andvascularendothelialgrowthfactor.Liquidconcentratedgrowthfactors(LCGFs)areanewerformofCGFs,whichareobtainedbycentrifugingthewholebloodwithoutaddinganticoagulants.

Inthisstudy,theresearchersinvestigatedtheeffectofLCGFsontheosteogenicabilityofhPDLSCs.TheresultsshowedthatLCGFssignificantlyimprovedtheosteogenicdifferentiationofhPDLSCsinaconcentration-dependentmanner.TheoptimalconcentrationofLCGFswasfoundtobe10%(v/v).Moreover,LCGFsincreasedtheexpressionofosteogenicmarkers,suchasalkalinephosphatase,osteopontin,andosteocalcin,andenhancedthemineralizationofextracellularmatrix.
