异种性

Chicken and quail intergeneric hybridization is a classic distant hybridization in fowl. In fowl science, chicken and quail belong to Aves, Galliformes, Phasiamidae, Gallus and Coturnix, and this hybridization combination has become the example of researching the incompatibility of different germ cell and sterile of distant hybridization.

鸡与鹌鹑杂交是属间杂交，其杂交种胚胎早期出现大量的死亡，并且杂交种出壳以前雌性胚胎全部死亡，这使鸡与鹌鹑杂交成为研究异种生殖细胞不亲和性和杂交种不育的典型。

RESULTS ① rhBMP2/BCB used alone was capable of healing the defect in large part by 16 wk, with a similar repair process and mechanism to that seen with RBX;② use of rhBMP2/BCB in conjunction with vascularized periosteal graft exhibited stronger defect-repairing power, basically healing the defect by 8 wk. The repair process consisted of intramembranous and endochondral ossification that resembled the physiological repair during the fracture healing.

结果①单纯rhBMP2/BCB移植，可在16 wk使节段性骨缺损基本修复，其机制与过程与重组合异种骨相似；②rhBMP2/BCB与带血循骨膜联合移植，仅用8 wk即可修复骨缺损，其修复机制与骨折修复相仿，包括膜内成骨和软骨成骨两种机制。

Objective To establish a simple pig-to-monkey xenograft model to study delayed xenograft rejection.

目的 建立一个简便的研究延迟性排斥反应的猪—猴异种心脏移植模型。

To provide basic parameters of evaluating the biological safety of xenotransplantation from pig to human, ear tissues from 31 individuals were randomly collected from a Shazi Ling pig population. PCR and RT-PCR were performed to detect porcine endogenous retrovirus proviral DNA and mRNA respectively. The sensitivity of the PCR was evaluated using a positive control.

为评价从猪到人异种移植的生物安全性提供依据，从湖南沙子岭猪的保种群内随机采集31头个体的耳样组织，应用PCR和RT-PCR技术分别检测这些组织中内源性逆转录病毒（porcine endogenous retrovirus，PERV）的前病毒DNA和mRNA，并对PCR扩增的灵敏性进行评估。
