Figure Lengend Snippet: Representative 1 H NMR spectra of MG63 cell metabolites after being cultured on different types of PLLA. The cells were seeded on PLLA, PLLA-Cel, PLLA-Col, and PLLA-Cel-Col for 7 days. Peak assignments: 1 – lactic acid, 2 – 3-hydroxy- l -proline, 3 – glucosylgalactosylhydroxylysine, 4 – lysine, 5 – glucosylproline, 6 – pyruvic acid, 7 – succinic acid, 8 – α-ketoglutaric acid, 9 – proline, 10 – 5-hydroxylysine, 11 – oxaloacetic acid, 12 – acetyl-CoA, 13 – FADH 2 , 14 – 2-phosphoglyceric acid, 15 – cAMP, 16 – 3-phosphoglyceric acid, 17 – phosphoenolpyruvic acid, 18 – NADH. Unassigned peaks represent unknown compounds not in the HMDB database, residual solvent signals, or overlapping signals. The water signal region (4.6–5.0 ppm) was excluded from analysis to minimize interference.
Article Snippet: The MG63 osteosarcoma cell line (ATCC CRL1427, USA) was cultured in a sterile NuncTM EasyFlaskTM 75 (Thermo Fisher Scientific, China) using DMEM (Gibco®, USA) enriched with 10% fetal bovine serum (FBS), 2% HEPES buffer, 1% MEM non-essential amino acids (NEAAs), and 1% PenStrep (Gibco®, USA).
