Not only will cross studies between both sides promote respective subject development, but also become the breach to reveal life origin,developmental biology of neoplasm and embryo and intrinsic mechanisms of embryo implantation and neoplasm invasion and metastasis.展开更多
文摘More and more studies indicate that there are many similarities such as pathophysiological process,gene expression,immune escape,angiogenesis and invasion characteristic between embryo implantation and neoplasm invasion and metastasis, which are taken for two "blackboxes" in medical field at present. Not only will cross studies between both sides promote respective subject development, but also become the breach to reveal life origin,developmental biology of neoplasm and embryo and intrinsic mechanisms of embryo implantation and neoplasm invasion and metastasis.
