Abstract
This paper aims to probe the cell differentiation and gene activity in early Oogenesis from Dendrolimus spectabilis Butler by transmission electron microscope. The 8 cystocytes are formed by mitosis of the Oogonia, and differentiated to the 1 Oocyte and 7 nurse cells. The oocyte and nurse cells are connected by ring canals, through which the cytoplasmic organelles such as mitochondria, free ribosomes, and electron dense granular materials are passed from nurse cells to o cyte. Many replication fork in the cystocyte nuclei and 2 transcriptional units of
