The Amazing Power of Cancer Cells to Recapitulate Extraembryonic Functions : The Cuckoo's Tricks

الملخص EN

Inflammation is implicated in tumor development, invasion, and metastasis.

Hence, it has been suggested that common cellular and molecular mechanisms are activated in wound repair and in cancer development.

In addition, it has been previously proposed that the inflammatory response, which is associated with the wound healing process, could recapitulate ontogeny through the reexpression of the extraembryonic, that is, amniotic and vitelline, functions in the interstitial space of the injured tissue.

If so, the use of inflammation by the cancer-initiating cell can also be supported in the ability to reacquire extraembryonic functional axes for tumor development, invasion, and metastasis.

Thus, the diverse components of the tumor microenvironment could represent the overlapping reexpression of amniotic and vitelline functions.

These functions would favor a gastrulation-like process, that is, the creation of a reactive stroma in which fibrogenesis and angiogenesis stand out.
