请用地道、专业、书面化、具有强逻辑性的英文表达如下内容：我们构建的HEO complex具有更优的内膜修复效果一方面可能得益于小鼠子宫内移植的上皮细胞可以直接参与到小鼠内膜的重建中体现在我们在EO移植组和HEO移植组均发现上皮细胞integrate in小鼠内膜的中。这是在其他内膜修复实验中未观察到的现象。另一方面移植物中血管的内皮细胞在移植过程中参与了移植物与受体移植部位的血管融合这个结果在两方

The HEO complex that we have constructed exhibits superior endometrial repair efficacy, which can be attributed to two main factors. Firstly, it is possible that the transplanted epithelial cells from the mouse uterus directly participate in the reconstruction of the mouse endometrium. This is evident from our observations in both the EO transplantation group and the HEO transplantation group, where we have observed integration of epithelial cells in the mouse endometrium. This phenomenon has not been observed in other endometrial repair experiments.

Secondly, the endothelial cells of the blood vessels in the transplanted tissue are involved in the fusion of the transplanted tissue with the recipient transplantation site's blood vessels. This result is supported by two aspects: firstly, we have observed a greater presence of lumen-like CD31+ endothelial cells in the endometrium of the HEO transplantation group; secondly, after subcutaneous transplantation in HEO mice, we have observed the fusion of blood vessels formed by human-origin endothelial cells with those formed by mouse endothelial cells, with peripheral blood perfusion.

The establishment of vascular network connections between the transplanted tissue and the recipient transplantation site is of great significance for the success of the transplantation. The vascular network with blood flow provides oxygen and nutrients, which are crucial for the survival and functioning of the transplanted tissue
