Cancer stem cells (CSCs), also known as tumor initiation cells (TICs), are undifferentiated cancer cells that can self-renew and differentiate into bulk tumor cells. They are thought to have a role in the resistance of tumors to therapy, and for disease recurrence.

Cancer stem cells (CSCs), also known as tumor initiation cells (TICs), are undifferentiated cancer cells that can self-renew and differentiate into bulk tumor cells. They are highly tumorigenic and are thought to be responsible, in some circumstances, for the resistance of tumors to chemo- and radiotherapy, as well as for disease recurrence following treatment. CSCs possess several characteristics that enable them to resist cancer therapies, including a slow cell cycle, resistance to oxidative stress, the ability to rapidly repair DNA damage and the capacity to expel anticancer drugs.
The origin of CSCs is unclear; they may derive from normal stem or progenitor cells or other cancer cells. Self-renewal of CSCs is through asymmetric division, by which one daughter cell retains the ability to self-renew, while the other will differentiate. CSC self-renewal and maintenance are regulated by various signaling pathways, including Notch, Hedgehog and Wnt, and these pathways are potential targets for new cancer therapies aimed at the elimination of CSCs and the prevention of relapse.

Written by Kirsty E. Clarke, Victoria B. Christie, Andy Whiting and Stefan A. Przyborski, this review provides an overview of the use of small molecules in the control of stem cell growth and differentiation. Key signaling pathways are highlighted, and the regulation of ES cell self-renewal and somatic cell reprogramming is discussed. Compounds available from Tocris are listed.
Stem cells have potential as a source of cells and tissues for research and treatment of disease. This poster summarizes some key protocols demonstrating the use of small molecules across the stem cell workflow, from reprogramming, through self-renewal, storage and differentiation to verification. Advantages of using small molecules are also highlighted.
