颅面骨骼的修复和再生的细胞为基础的方法，利用干细胞通过重新组织形成提供了保证。脂肪基质细胞（ASCs）已被证明是一个丰富的来源，能够进行成骨细胞，软骨细胞，脂肪细胞和成肌细胞分化的多能干细胞。许多研究探讨了这些细胞在体内的成骨潜能细胞输送各种脚手架生物材料的使用。它已被证明，通过利用一个骨传导，以羟基磷灰石涂敷的聚（乳酸 - 共 - 羟基乙酸）（HA-PLGA）支架种子与先进的结构陶瓷，颅骨缺损的关键尺寸，其无法进行自发定义的缺陷，这会愈合的动物的整个生命周期，可有效地显示出强劲的骨再生。这在体内模型演示旨在再生的骨组织的基础上的平移的方法-在蜂窝成分和生物基质。这种方法的模型作为最终的临床应用祖细胞对一个特定的组织缺损的修复。
