COMPARATIVE STUDY OF MORPHO-HISTOLOGY OF OVARIES OF WT (HDRR) AND P53 (-/-) OF MEDAKA (ORYZIAS LATIPES)

Abstract

In the present paper comparative study of morpho-histology of ovaries of both WT (HdrR) and P53
(-/-) of medaka (Oryzias latipes) has been done. The ovaries of adult are paired and oval-rounded in shape and are
situated ventrolaterally. Histologically the ovaries consist of follicles with various stages of development, such as
primodial follicle, large follicle and growing follicle. Also, the ovaries can be differentiated into outer functional
regions and inner non-functional regions. The histological structure of the ovary in both strains fishes represents
the generalized teleostean structure with some differences in follicles count and distribution. We conclude that, the
difference recorded in the present study has an impact on the maturation inside and eggs release from the ovaries.
