Propolis Ethanol Extract Stimulates Cytokine and Chemokine Production through NF-κB Activation in C2C12 Myoblasts

Figure 4

Effect of supernatant from PEE-conditioned C2C12 cells on mRNA expression of angiogenic factors in macrophages. Results of qRT-PCR analysis of RAW264 cells treated for 12 h with supernatant from C2C12 cells conditioned with either 100 μg/mL PEE or vehicle for 8 h. Data normalized to 18S rRNA (means ± SD of four samples). versus supernatant from vehicle-conditioned control cells.
