The typical pathological characteristics of SPTs may result from gradual degenerative changes induced anoxemia in some SPT's areas. The heterogeneity of SPTs on different antibody markers showed that the SPTs may be originated from pancreatic embryonic stem cells, and result from immature differentiation of the pluripotential stem cells during pancreatic genesis.

SPT典型病理特征是由于肿瘤组织不同区域相对缺血、缺氧所造成的退行性变的结果，SPT表达多种组织来源的抗原，反映其可能来源于胰腺干细胞及与其发育密切相关的胚胎神经嵴的神经前体细胞，且在发育过程中发生分化不成熟的结果。

Since the embryonic cells possess lower antigenicity and stronger proliferation capability, it is hoped that they can be used as a novel carrier substitute in tissue engineering research.

由于胚胎细胞具有较低的抗原性和较强的增殖能力，期望其能为组织工程研究与应用开辟新的载体材料。
