Introduction Angiogenesis plays a central role in the growth and development of normal tissues and in a variety of pathological settings. It is a complex multistep process involving growth and migration of endothelial cells, and capillary morphogenesis . These processes are tightly controlled by positive and negative angiogenic factors and their receptors, which regulate one or more of these key events[1-3]. Although the regulatory mechanisms of angiogenesis are not fully understood, evidence … 相似文献

The mammalian zona pellucida (ZP) is a transparent, porous sulfated glycoproteinextracellular matrix that surrounds growing and mature oocytes as well as the fertilizedovum before implantation. It mediates the initial spermatozoon-egg interaction involved inrecognition, binding and penetration of spermatozoon to oocyte in a relatively species-specificmanner, and plays an important role in the subsequent activation events including inductionof the acrosome reaction as well as the primary block … 相似文献

It was well known that the genotoxicity and the carcinogenic effects of benzene weredemonstrated[1,2]. Recently more attention had been paid to the effects of benzene on humanreproduction. These studies focused on the female reproductive system[3] or the semen,such as volume, viscosity and liquefaction[4]. Few articles reported investigating the effectsof benzene on sperm DNA that was crucial for human reproduction[5].The purpose of this study was to assess sperm DNA damage in workers expos… 相似文献
