Could Cancer Initiate From Bone Marrow Progenitors?

BACKGROUND Defining cancer stem cells and their origins is of much controversy,and constitutes a challenged knockout for cell targeting- anticancer drugs. Herein,we put forward a hypothetic model for cancer stem cells initiation from bone marrow stem cells. These later, will differentiate into an ancestral progenitor that activates a memorial program - the black box cassette- that is responsible of abnormal neo-organogenesis in the form of tumors and metastases. To approve this model, we assume that characterizing and investigating the most primitive forms of the bone marrow progenitors is required; both inside their niche and in circulation of cancer patients.
