چکیده: In this study, the ultrastructural development of germ cells in the ostrich embryo was analysed. The
nuclear organisation and morphological characteristics of cytoplasm in the developing germ cells, on
embryonic days 20, 26, and 36 and the day of hatching (5 samples from each stage) was analysed
using transmission electron microscopy (TEM). Germ cells located in the cortex of left ovaries were
identified by their large size and centrally located nucleus, with a conspicuous nucleolus. In these
cells, the cytoplasm contained an abundance of mitochondria and free ribosomes. The structure of
Balbiani body, a villous-like elevation in wide intercellular space and desmosome junction between
two adjacent germ cells was also studied. The germ cells during embryonic development showed
structural differences in both the nucleus and cytoplasm.
