Abstract:
During chick embryo development, the liquid crystals appear in more
than 20 organs at certain developmental stages, and vanish in early
post-natal stage. In this study, we found a complex in embryo, the YS-J/I
tunnel system, in charge of transporting the LCs and CCVCs preserved
from yolk sac into the embryo. This transportation initiates from yolk sac
connecting to central transportation region/reservoir via a main tunnel,
spreads radically to various parts of digestive system via sub-tunnels.
Our data indicate that the liquid crystals could be the best form of nutri-
tion which is necessary in embryo development and early post-natal
development
