From: Nitric oxide synthase activity in human trophoblast, term placenta and pregnant myometrium
NOS activity in particulate (par) and cytosolic (cyt) fractions isolated from early placenta (first trimester) villous (n = 17) and non-villous (n = 17) trophoblasts. Significance of differences between villous and extravillous are shown by ** (p < 0.01) and *** (p < 0.005).
