Echoes of phlogiston in stem cell biology
Date:9/21/2009

cise nature of stem cells may be the assumption that specific chemotherapeutic targeting of 'cancer stem cells' will necessarily stop tumors in their tracks. As Lander writes, "If feedback and lineage progression continue to take place in cancerous tissues, we might observe that under different conditions - different stages of tumorigensis, different parts of a tumor, different amounts of tumor cells - that different cell types will assume the role of cancer stem cell".

He concludes, "Like phlogiston, the term 'stem cell' is a scientific concept. Just as investigating the concept of phlogiston allowed the discovery of oxygen and the process of oxidation, it may be that by refashioning our thinking about stem cells with systems relationships and dynamics taking the place of molecular signatures and simple gene regulatory circuits - the concept of stemness will continue to light the path toward understanding".
