Effects of an Epidermal Growth Factor on the Growth ofZeaColeoptiles

摘要

Sections of the elongation zones of coleoptiles ofZea maysL. were incubated in buffers containing various concentrations of human epidermal growth factor (EGF). The growth rate of sections incubated with 10, 1.0 or 0.1figliter1EGF was higher than that of control. EGF at 10figliter−1increased the growth rate by13%of the control rat
