SEMA4A and posterior cortical atrophy: To further elucidate the role of SEMA4A in PCa, protein array was applied to detect the expression profile of WPMY-1, which was a kind of myofibroblasts, after rhSEMA4A stimulation and IL-10 exhibited the most obvious induction, which was further confirmed by analyzing its secretion in the supernatant of WPMY-1.
