Because of a production error in the Research Article “MEK-SHP2 inhibition prevents tibial pseudarthrosis caused by NF1 loss in Schwann cells and skeletal stem/progenitor cells” by S. Perrin et al., the references cited in the Supplementary Materials were missing from the published article. These references have been added to the References and Notes list as numbers 57 to 68 in the PDF and the HTML, and the Supplementary Materials PDF has been updated with these reference numbers. The data and conclusions are not affected.

In-deed!

In this teaser you place a small word in "de...ed" to produce a new word. The letters are inserted in order, as a whole.

Each cryptic clue has two parts:
* first, a clue for the small word
