hedgehog signalling pathway has not only a critical role in cell proliferation, differentiation and tissue polarity at embryonic period but also has a vital role in stem cell proliferation, tissue healing and carcinogenesis. recent research has increased our understanding of this pathway and its relation to other signalling pathways. in addition, a large number of studies confirmed the alterati...

PURPOSE Retinoblastoma (RB) is the most common intraocular tumor of early childhood. The early onset of RB, coupled with our previous findings of cancer stem cell characteristics in RB, led us to hypothesize that subpopulations of RB tumors harbor markers and behaviors characteristic of embryonic and neuronal origin. METHODS Our RB sources included: human pathological tissues, and the human R...

Stem cell technology has been recognized as an emerging technology that could transform current supportive approach toward curing many chronic disorders and degenerative conditions. Regenerative medicine is the promising area of medical practice in the coming decade. However, stem cell technology also brings up controversial issues from the bioethical perspective such as the destruction of huma...
