Schwann cells colocalize with motor nerve terminals in Lama4^−/−;Lama5^M/M NMJ. En face view of NMJs from Lama4^−/−;Lama5^M/M and control mice were stained with antibodies against Schwann cells (S100, green), nerve terminals (neurofilament + SV2, blue), and AChRs (BTX, red). Schwann cells colocalized with the nerve terminal but did not cover the unoccupied AChR clusters in the mutant. Bar, 10 μm.
