Blood vessel staining using MECA-32 antibody and alpha-smooth muscle actin (α-SMA) antibody on tissues surrounding SC implanted catheter from mice with three-month diabetic history at day 14, 30, and 90 post-implantation. Skin tissue samples collected from mice with three-month diabetic history without receiving implantation surgery were used as a control. SC: subcutaneous; C: catheter. Arrow indicates newly formed blood vessels around the zwitterionic gel treated catheter. Scale bar, 100 μm.
