Class I Biocompatible DLP-Printed Acrylate Impairs Adhesion and Proliferation of Human Mesenchymal Stromal Cells in Indirect Cytotoxicity Assay

Figure 3

Results of spectrophotometric analyses for adherent, dead, and nonadherent living cells. Significant differences of each material compared to reference are indicated in the respective color, significant differences compared between 24 h and 7 days of indirect cell culture of each material are indicated in orange, and significant differences after 7 days culture between “fresh” and “stored” are indicated in red. Data plotted as means () with SD as error bars. Significance levels are indicated with “.” A number of adherent, dead, and nonadherent cells after 3-day expansion on the plate and before indirect culture with materials are indicated as red line, respectively.
