Feltri et al. (2001)(this issue) succeed in disrupting ß1 integrin specifically in Schwann cells, and in so doing, demonstrate that it is required for normal myelination. Their results reveal that signaling by an extracellular matrix receptor plays a key role in the differentiation of myelinating Schwann cells.
