We studied the effect of norepinephrine and selective β1-adrenoceptor blockers on the growth of retinal tissue explants from 10-12-day-old chicken embryos in organotypic culture. The test drugs produced a dose-dependent effect on cell proliferation. Norepinephrine (10−12 M) and atenolol (10−4 M) are shown to signifi cantly stimulate explant growth. Combined treatment with norepinephrine (10−12 M) and atenolol (10−4 M) results in cumulation of their stimulatory effects. The results suggest that the retina-stimulating effect of norepinephrine is based on its interactions with other types of adrenoceptors.
