Fig. 2From: Evaluation of oral keratinocyte progenitor and T-lymphocite cells response during early healing after augmentation of keratinized gingiva with a 3D collagen matrix - a pilot studyCell viability. Graph representing the percentage of α6β4+/CD71+ cells cells at different time points: 0, 7 and 14 days. At each analyzed time point most cells were found viable in all analyzed samples, with rare necrosis (each sample identifies different individuals; n = 5, p <0.05 Student’s t-test)Back to article page
