CASP2 is activated in serum-withdrawn DRGN and satellite cells.

<p><b><i>A</i></b>, CASP2, C-CASP2 and <b><i>B</i></b>, CASP3, C-CASP3 in DRGN and satellite cells grown in the presence of serum (D+S) or after serum withdrawal (D−S). <b><i>C</i></b>, Double immunostaining for C-CASP2 in βIII-tubulin⁺ DRGN (arrow) and C-CASP2⁺ in βIII-tubulin⁻ satellite cells (arrowheads). Scale bars in <i>A</i>–<i>C</i> = 50 µm.
