Effect of K⁺ current blockers on cellular functions of cultured fibroblasts. Fibroblasts were cultivated with normal culture medium (control) or medium supplemented with 1 mmol/L tetraethylammonium and 1 mmol/L 4‐aminopyridine (TEA + 4‐AP). Proliferation (A; SR, n = 10; AF, n = 6), migration (B; SR, n = 4; AF, n = 3), and differentiation (C; SR, n = 5; AF, n = 5) were assessed as described in Figure 2. *P < 0.05, two‐tailed unpaired Student's t‐test. ^# P < 0.05, ^## P < 0.01, paired Student's t‐test.
