There was an error published in the online version of In This Issue, Development136 (23).

The item ‘Stem cell neuronal differentiation in mice and men’ incorrectly listed page 4053 and as such linked to the wrong paper.

It should have listed page 4055 and thereby been linked to the correct paper: Li, X.-J. et al. (2009). Coordination of sonic hedgehog and Wnt signaling determines ventral and dorsal telencephalic neuron types from human embryonic stem cells. Development136, Stem cell neuronal differentiation in mice and men.

The online version has now been corrected. The print copy is correct.

We apologise to authors and readers for this mistake.
