We have measured the activities of the two rate controlling enzymes in polyamine synthesis, L-ornithine decarboxylase (ODC) and S-adenosyl-L-methionine decarboxylase (SAMDC), and the concentrations of the polyamines, putrescine, spermidine and spermine, in the developing chick embryo from laying to hatching. The embryo exhibited major peaks in the ODC and SAMDC activities as well as in the concentrations of all three polyamines at 15 h (gastrulation), 23-30 h (early organogenesis), days 4-5 (mid-organogenesis), and days 12-17 (organ growth and maturation). In the 4 and a half-day-old embryo, ODC activity and polyamine concentrations were about twice as high in the head region as compared to the trunk region. In the 14-day-old embryo, the highest ODC and SAMDC activities were found in lung, intestine and kidney, and there was a positive correlation between the enzyme activities and the growth rates of most organs/tissues.
