Figure 4. In vivo tumor penetration of Cis-Pt released from implants.
(A) Assessment of Pt distribution in different sections of the tumors after treatment with empty or Cis-Pt implants using two different methods: ICP-MS and immunofluorescence (IF). (B) Pt concentration in each tumor layer from Cis-Pt implant group (n=3) by ICP-MS analysis, adjusted with background signal from empty implant group (n=3). (C) Fluorescence microscopy images of regions of tumor sections, stained with antibody for Cis-Pt induced DNA adducts (AF488) and counterstained with DAPI. Gray lines indicate the edge of the tissue.
