Figure 2. SSP-mediated neurite-like outgrowth of SCLC cells on ECM constituents.

Cells were seeded on PO- or ECM-coated Petri dishes (a FIB substrate was used, with the exception of SCLC-24H cells, where LAM was used as a substratum) and cultured for 24 h in the absence (−) or the presence (+) of 20 nM SSP. Bar: 100 µm.
