Figure 4:

Effects of TNF-α and EMF exposition on the transcriptional expression of CD68 (A) and CD45 (B) in HMC3 cells. Cells were incubated with TNF-α (50 ng/mL) and exposed to an (EMF) of 2.5 Hz or 5 Hz for 3 min. RNA samples were purified after 6, 24 and 48 h. TNF-α: tumor necrosis factor alpha; EMF: electromagnetic field; CD68: cluster of differentiation 68 or microsialin; CD45: cluster of differentiation 45 or protein tyrosine phosphatase, receptor type, C (PTPRC).
