Histological Studies of Interstitial Cells in the Ovaries of Bats Hipposideros Speoris and Megaderma Lyra Lyra
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 3
Abstract
Bats are the most diverse and successful group of mammals exhibiting many adaptive specializations. Chiroptera shows great variations in the reproductive stage, even the closely allied species exhibit different breeding habits. It is important to study the reproductive organ that is ovary in respect with the interstitial cells. Because the interstitial cells with the help of LH of pituitary produce a hormone androgen. That means interstitial tissues are developed as a gland having steroidogenic activities. In the immature ovary of Hipposideros speoris, interstitial cells are not distinguished from the stromal cells while It is clearly distinguished from stromal cells. In the inactive Hipposideros speoris ovary, bundles of interstitial cells observed 60 ± 5. The immature ovary of Megaderma lyra lyra showed the small bundles of few interstitial cells in stromal region. In inactive ovary of Megaderma lyra lyra, interstitial cell bundles observed 48 ± 5. Number of interstitial cells in each bundle observed in inactive ovary of Hipposideros speoris are 5 to 10 and in Megaderma lyra lyra it is observed 5 to 7. In the active ovary of Hipposideros speoris, the bundles of interstitial cells observed 80 ± 5 and in Megaderma lyra lyra observed 56 ± 5. Number of interstitial cells in each bundle observed in Hipposideros speoris is 20 to 30. while in Megaderma lyra lyra observed 10 to 20. Pregnant ovary of Megaderma lyra lyra showed extrovert carpus luteum, atretic follicles and destructed interstitial cells. So it is concluded that the interstitial cells in the active ovary is more steroidogenic than inactive ovary
