Abstract
|
|
Aims:
This study was undertaken to reveal the ultrastructural details of preantral ovarian follicles and corpus luteum in Indian flying fox Pteropus giganteus.
Methods: Five specimens were collected during estrous, early pregnancy and mid-pregnancy from the feeding sites. Reproductive stages were confirmed by the histological examination of the uterus and ovaries. The ultrastructural details in the preantral follicle and luteal cells were studied using transmission electron microscope. Results: Primordial graffian follicle (type-1) was composed of an oocyte surrounded by incomplete layer of 4–5 flattened granulosa cells resting on the basement membrane. In primary follicles oocyte was encircled by single layer of 10–12 cuboidal granulosa cells. Oocyte possesses numerous bent microvilli. In small preantral follicle (type-3), complete two to four layers of cuboidal granulosa cells were noted. Zona pellucida appears at this stage. Large preantral follicles (type-4) possessed four to six layers of granulosa cells resting on basement membrane. Single extrovert type of corpus luteum was observed during early to mid-pregnancy. Diameter of large luteal cells during early and mid pregnancy were 22.46±0.56 µm and 22.85±0.56 µm and of small luteal cells were 17.81 ± 0.40 µm and 17.34 ± 0.46 µm respectively. Conclusion: Biphasic pattern of development of preantral follicle had been observed in Pteropus giganteus. Oocyte of large preantral follicles (type-4) was characterized by the presence of cortical granules in the cortical region. Ultrastructural features of large and small luteal cells confirms to the criteria of steroid secreting cells. No significant differences were noted in the diameter of large and small luteal cell during early and mid-pregnancy. | |
