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。

RESULTS:①Hematological restitution: After transplantation, 4 cases of pure red cell aplasia occurred, 3 in major and 1 in bidirectional ABO-incompatible.

结果：①造血重建：细胞移植后，共4例发生纯红细胞再生障碍性贫血，其中ABO血型主要不合患者3例，双向不合患者1例。

The secondary nuclei can fertilize normally and form nuclear type endosperm while some constitute cellular endosperm, All of them degenerate 12 days after pollination,with the result of the ovules being aborted earlier while the arillus still occur and develop into seedless fruit finally.

次生核虽正常受精，并产生核型胚乳，有的还能发育到细胞型胚，到 12d左右也完全退化。结果导致胚珠极早败育，但假种皮仍能发生发育，最终形成无核果实

In aspermous Patients the reason is the obstruction of spermatogenesis, the most common obstruction occurs in the spermatid level.

在无精症患者中是由生精阻滞所致，最常见的阻滞发生在精子细胞水平。
