Proteomic Changes of Tissue-Tolerable Plasma Treated Airway Epithelial Cells and Their Relation to Wound Healing

Figure 4

Principal component analyses (PCA) of proteomes of untreated and TTP treated S9 cells. The first and second principal components for untreated and TTP treated (30 s, 60 s, and 120 s) S9 epithelial cells after different points of time (24 h, 48 h, and 72 h) are shown. Each group consists of four technical replicates, except for the 24 h time point of 60 s and 120 s TTP treatment (only 3). The distances of shifts in space are illustrated by arrows. Arrows 1a, 2a, and 3a display the deviation of untreated samples and different treated samples after 24 h. Arrows 1b, 2b, and 3b represent the shift of treated samples after 24 h compared to their corresponding 48 h time point.
