支架是在组织工程应用中再生新的骨骼和骨骼组织生长的地方。hADMSC是一种能分化为成骨，成软骨和成脂细胞的多能细胞。Y-TZP由于其坚硬的特性（即断裂韧性和高弯曲强度）而被证明比其他陶瓷具有多个优势。本研究旨在通过体外分析来分析Y-TZP作为hADMSCs接种的支架的生物相容性。这项研究涉及多个过程，即Y-TZPS制造过程，XRD检查，hADMSC的区分和表征，SEM观察以及TT。XRD结果显示，

支架是在组织工程应用中再生新的骨骼和骨骼组织生长的地方。hADMSC是一种能分化为成骨，成软骨和成脂细胞的多能细胞。Y-TZP由于其坚硬的特性（即断裂韧性和高弯曲强度）而被证明比其他陶瓷具有多个优势。

本研究旨在通过体外分析来分析Y-TZP作为hADMSCs接种的支架的生物相容性。这项研究涉及多个过程，即Y-TZPS制造过程，XRD检查，hADMSC的区分和表征，SEM观察以及TT。

XRD结果显示，Y-TZPS具有尖峰。这表明它们具有较高的晶体纯度。hADMSC表征显示，NMT上方的CD 90，CD 73和CD 105，以及CD 14，CD 19，CD 34，CD 45和HLA- DR低于NLT。随后用SEM对Y-TZPS的观察结果进行分析，结果表明Y-TZPS具有孔隙，HADMSCs粘附并在Y-TZPS孔隙中增殖。

综上所述，该研究结果表明，低孔隙度和毒性的Y-TZPS能够促进hADMSC的增殖和分化。预期将使用具有高生物相容性的hADMSC将Y-TZPSs用作可植入生物材料。
