Abstract

The diagnosis of neoplastic disease still lays its foundations on the detection of altered tissue morphology. Most importantly, cancer begins, at least in many cases as a disease with altered tissue pattern formation. It is therefore rather surprising that the issue regarding the possible mechanistic role of such property in the pathogenesis of cancer has received relatively little attention so far. To be more specific, we need to ask the following question: is altered tissue pattern formation a mere bystander, with its pervasive presence along the entire carcinogenic sequence, or does it play a role in fuelling this process? Pathways related to morphogenesis and to the establishment of cell polarity will be considered for their possible mechanistic involvement in early phases of neoplastic disease. Evidences and hypotheses relating altered tissue pattern formation to the emergence of the tumor microenvironment and to neoplastic progression will be discussed.
