Haemoglobin Synthesis

1. After 24h of incubation, the blastoderm may be dissected from the early developing chick embryo and successfully maintained under conditions of organ culture in vitro. 2. Low concentrations of steroids related to 5beta-androstane stimulate the synthesis of foetal haemoglobins, types E and P, in a highly steroid- and tissue-specific manner.

Hind Gut

The allantois of the chick appears at about the 3rd day of incubation as an evagination from the hind gut; it soon becomes distended with fluid, enlarges rapidly, and fuses with the chorion to form the chorio-allantoic membrane. Out of curiosity, the allantoic sac of a 4-day chick embryo was explanted in a watchglass culture to see how it would behave in vitro. Under these conditions the allantoic endoderm did not develop into a flattened, granular layer as in normal embryonic life, but instead differentiated into a tall, columnar epithelium with many actively secreting goblet cells, which closely resembled that of the large intestine. This casual observation was investigated further and the results of the study are described below. The allantoic sac was removed from 3½-4½-day embryos, before fusion with the chorion had taken place; the neck of the allantois, uniting the latter with the gut, was excluded from the explants.

We studied the effect of sodium selenite (Se) on the secondary metabolism of Lychnis chalcedonica L. cell culture in vitro. It was found that low concentrations of Se reduce the flavonoid content, but do not change the content of saponins.
