Metabolomic profiling for identification of metabolites and relevant pathways for taurine in hepatic stellate cells

Figure 2 Partial least square discriminant analysis and validation of biological metabolites for taurine in hepatic stellate cells in electrosprayionization⁺ mode and in electrosprayionization^- mode. A: Partial least square discriminant analysis (PLS-DA) plots of biological metabolites for taurine in hepatic stellate cells (HSCs) in ESI⁺ mode; B: PLS-DA plots of biological metabolites for taurine in HSCs in ESI^- mode; C: Validation of biological metabolites for taurine in HSCs in ESI⁺ mode; D: Validation of biological metabolites for taurine in HSCs in ESI^- mode. ESI: Electrosprayionization; HSCs: Hepatic stellate cells.
