Figure 4From: Angiotensin-II Mediates Nonmuscle Myosin II Activation and Expression and Contributes to Human Keloid Disease ProgressionAng II-induced proliferation of keloid fibroblasts. Keloid fibroblasts were serum starved overnight, followed by 24-h stimulation with Ang II (10−6 mol/L) at the indicated conditions. The MTS assay was used to determine proliferation. Ang II significantly increased proliferation. AT1 antagonists decreased Ang II-stimulated proliferation, whereas AT2 antagonist did not. *P ≤ 0.05Back to article page
