Fig. 10From: Intracellular pH-responsive and rituximab-conjugated mesoporous silica nanoparticles for targeted drug delivery to lymphoma B cellsTUNEL assays showed that tumors treated with RDMSNs exhibited significantly more apoptosis DNA compared to those of other groups. Histological apoptosis observation in tumor tissues by TUNEL staining after the tumor-bearing mice were treated with Saline, Free DOX, DMSNs, and RDMSNs for 16 days, respectively. Green: apoptosis DNA; Blue: cell nuclei. Scale bar: 50 μmBack to article page
