(scale bar = 50 µm).

Article Snippet: For determination of growth factor release from the hydrogels, gelatin hydrogels were loaded onto 0.4 μm PET membranes within a 24 well plate, submerged in PBS, and growth factor release quantified at 0, 12, 24, 48, 96 and 120 h using respective Quantikine ELISA kits (R&D Systems, DEG00 for EGF, DBB00 for PDGF-BB, and DVE00 for VEGF).

Figure Lengend Snippet: a, Top: Scheme of metabolomic analysis using extracts from nerve segments. Bottom: Concentrations of key energy metabolism intermediates in control and axotomized nerve segments from C57Bl/6J mice (F6P/G6P: fructose-6-phosphate/glucose-6-phosphate. FBP: fructose-1,6-bisphosphate. GI-OH3P: Glyceraldehyde-3-phosphate. 2PG/3PG: 2-phosphoglycerate/3-phosphoglycerate. LACT: lactate) (Error bars represent s.e.m. n=5 mice per condition and metabolite). b, Top: Scheme of extracellular flux analysis of SCs purified from C57Bl/6J mouse nerves. Bottom: Box and whiskers plot (maximum, 25th percentile, median, 75th percentile, minimum) shows glycolytic activity parameters as assessed by extracellular acidification rate (ECAR) measurements in control mouse SCs and cells with Nrg1-induced ErbB2 activation (n=9 well preparations per condition, *P=0.0080, **P=0.0464, ***P<0.0001). c, Western blot analysis (cropped blot images) of control- and Nrg1-treated C57Bl/6J mouse SCs probed with the indicated antibodies. (n=6 independent pair preparations (2 separate dishes) for PFKFB3, and n=3 independent pair preparations (2 separate dishes) for LDHA quantification). d, Intracellular and extracellular (supernatant) lactate concentrations from control and Nrg1-treated mouse SC preparations normalized to cell number and cellular protein. Note decreased intracellular and increased extracellular lactate levels in SCs treated with Nrg1 for 24h, indicating greatly increased lactate extrusion (Error bars represent s.e.m. n=3 well preparations from 3 independent experiments per condition).

Article Snippet: SCs were subsequently control-treated or treated with 200 ng/ml recombinant Nrg1 (R&D Systems, 396-HB-050) for 24h, collected in RIPA buffer containing phosphatase and protease inhibitors, and then processed for protein analysis and western blotting using standard procedures.
