Profilin 2 promotes growth, metastasis, and angiogenesis of small cell lung cancer through cancer-derived exosomes

Figure 3. Exosomes derived from H446 cells. The exosomes are identified using TEM, NTA and western blot (A–C). PFN2 expression in exosomes derived from different kinds of H446 is detected using western blot (D). Exosomes can be internalized by H446 cells (E).
