Figure Lengend Snippet: Increased mechanical stiffness induces MPTP opening and mitochondrial damage in macrophages. (A) MH‐S cells were incubated with different stiffness matrix gels for 24 h. Mitochondrial membrane potential was labeled using the mitochondrial membrane potential probe JC‐1 and detected by flow cytometry, n = 6 biological replicates. (B). MH‐S cells were incubated with different stiffness matrix gels for 24 h. Mitochondrial reactive oxygen species content in cells was measured by using the mitoSOX probe and detected by flow cytometry, n = 5 biological replicates. (C). MH‐S cells were incubated with different stiffness matrix gels for 24 h. Calcium ion concentration in cytoplasm was detected using flow cytometry, n = 5 biological replicates. (D). MH‐S cells were incubated with different stiffness matrix gels for 24 h. MPTP activity of macrophages after matrix gel culture was assayed using the MPTP kit, scale bar = 100 µm, n = 6 biological replicates, stronger green fluorescence corresponds to reduced MPTP opening and preserved mitochondrial integrity, while weaker fluorescence indicates elevated MPTP opening and impaired mitochondrial structural integrity. (E). MH‐S cells were incubated with different stiffness matrix gels for 24 h. Expression of mitochondrial membrane permeability transition pore‐associated genes ANT1 and CypD detected by qPCR, n = 5 biological replicates. (F). MH‐S cells were incubated with different stiffness matrix gels for 24 h. Expression of ANT1 and CypD was detected by WB, n = 5 biological replicates. (G). MH‐S cells were incubated with different stiffness matrix gels for 24 h. Expression of CD163 and iNOS was detected by WB, n = 6 biological replicates.
