PTEN and neoplasm: In particular, PPARγ (Fig. 7d), PTEN (Fig. 7g), and CD36 (Fig. 7j) expression in F4/80-positive cells (red) was also markedly enhanced by apoptotic cell injection, which reflects apparent PPARγ, PTEN, and CD36 induction in tumor-associated macrophages (TAMs), as the F4/80-positive macrophage intensity was not different (Fig. 7c).
