SLC2A4 and cancer: (Figure 8A–E) Aside from the artificial receptor transfering for cancer diagnosis, Bio‐MVs have excellent performance in integral membrane proteins such as CD63‐GFP and glucose transporter‐4 (GLUT4‐GFP) delivery.[27a] When the GLUT4 transfer to mouse muscle membranes, it will retain its functionality and allowing the increased glucose uptake of recipient cells.
