Abstract

Glycogen content and the enzymes of glycogen metabolism have been measured in the post implantation rat embryo over a period ranging from 9.5 to 18.5 days of gestation. The earliest periods studied were at days 9.5 and 10.5 of gestation, when the yolk sac becomes vascularized and heart beat is first established. The next intervals were at days 11.5 when vascular connections via the allantoic placenta are formed. At 14.5 and 18.5 days of development, 4 entire organs were analyzed: heart, liver, kidney and brain. The metabolic apparatus of glycogen metabolism was concentrated in the embryo at 10.5 days, then the heart region, and in the heart itself at later stages.
