Stem cells are unspecialized cells that are capable of self-renewal through mitotic cell division, even after long periods of inactivity. Stem cells may be induced to form more specialized cells of a tissue or organ by a process termed cellular differentiation, which is defined by the potency of a cell.
Owing to their regenerative potential, stem cells in some tissues and organs are utilized to repair or replace old or damaged cells and this property may be useful in regenerative medicine. In other tissues such as the heart, this does not occur and stem cells only divide under strict conditions.
The four main types of stem cells are: embryonic stem cells (ESCs) found in the inner cell mass of blastocysts; adult (or somatic) stem cells, found in adult tissues and responsible for maintenance and repopulation of specific cell types; induced pluripotent stem cells (iPSCs), produced by the reprogramming of somatic cells; and cancer stem cells (CSCs).
Cryopreservation for storage of cells is a key step in stem cell protocols. The ROCK inhibitor Y-27632 improves post-thaw survival rates. This blog post outlines how this compound protects stem cells from dissociated-associated apoptosis.Read Now!
Stem cell therapies have the potential to treat several diseases, and these therapies are now entering clinical trials and approaching the clinic. This blog discusses small molecules as an ancillary material (AMs) for stem cell therapy manufacture, including their advantages over other types of AMs.Read Now!
Small molecules are increasingly being used alone, or in combination with growth factors, to modulate stem cells. They can be used at all stages of the stem cell workflow, i.e. in reprogramming, maintenance, storage and differentiation protocols. This blog post outlines the advantages of using small molecules.Read Now!

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.
