mitochondria with clear cristae, pigment granules, and irregular cell membranes,
x 40,000 (Karasaki).
embryos, Eakin and Lehmann (1957) point out a special form and
arrangement of mitochondria in the epidermis, whose functional
connection with the secretory activity of the cell is apparent. According
to Karasaki (unpublished work) the mitochondria of the epidermis cells
of the Rana embryo also can clearly be distinguished from the mitochondria of the neural cells.
with the reports cited above, may suggest that one of the effects of
the organizer on the reacting ectoderm cells is the enhancement of
mitochondrial activity.
It is interesting to note that the mitochondrial population differs in
morphological features according to the embryonic areas. In Xenopus
