Fig. 5From: Transcriptomics and metabolomics reveal changes in the regulatory mechanisms of osteosarcoma under different culture methods in vitroThe metabolomic analysis of OS cells and tissue under different culture methods. A, B, C, and D represent the classification trend diagram (PLS-DA) and evaluation diagram obtained by comparing the D-2 group, D-3 group, DP-3 group and IT group with the FIT group, respectively. The first two graphs of each group are PLS-DA in positive and negative ion modes, and the last two graphs are 200 times cross validation for the models constructed in both modesBack to article page
