Mechanical stretch promoted the expression of M1-related mRNA and cytokine secretion of RAW264.7 macrophages. (a) IL-1β, IL-6, TNF-α, and iNOS concentration in the cellular supernatant after 5%, 10%, and 15% Elong mechanical stretch for 8 h. Control indicates cells were cultured at static condition. (b) IL-1β, IL-6, TNF-α, and iNOS mRNA expression levels after 5%, 10%, and 15% elongation mechanical stretch for 8 h. Control indicates cells were cultured at static condition. The results are expressed as the means ± SD (n = 3). Compare to control, ∗P < 0.05 and ∗∗P < 0.01.
