Figure 4. S1PR2 mediates Nogo-A-Δ20- and myelin-induced inhibition of cell spreading and neurite outgrowth.

Figure 4

(A,C) Representative pictures of 3T3 fibroblasts treated with JTE-013 or vehicle (DMSO) (A), or stably carrying a S1pr2 shRNA (sh-S1pr2) or empty vector (sh-Vec) construct (C) and plated on control, Nogo-A-Δ20 or myelin substrates. (B,D) Cell spreading quantification of (A) and (C). (E) Representative pictures of MEFs isolated from WT or S1PR2−/− mice and plated on control, Nogo-A- Δ20, or myelin substrates. (F) Cell spreading quantification of (E). Cells were stained with Alexa488-conjugated Phalloidin in (A, C, and E). (G,I) Representative pictures of P5–8 cerebellar granule neurons treated with JTE-013 or DMSO (G), or isolated from S1PR2−/− or WT mice (I) and plated on PLL (ctrl), Nogo-A-Δ20 or myelin substrates. (H,J) Normalized mean neurite length per cell quantification of (G) and (I). Neurons were stained with βIII-Tubulin in (G) and (I). Data shown are means ± SEM (n = 3–6 experiments; *p<0.05, **p<0.01, ***p<0.001). Scale bars: 50 µM.
