Histomorphology Of One-Humped Dromedarian Uterus during three Pre-Natal Developmental periods

Camelus dromedarius (Dromedary or one-humped camel) belonging to the genus Camelus, is recently receiving great research attention due to the increasing importance of this species as model for scientist in various discipline of biological science including reproduction. This study was aimed to evaluate histomorphological horizons during uterine development at three pre-natal stages in dromedary. Twenty-two fetuses were used to study the uterine horns, uterine body and uterine cervix histomorphological horizons in three trimesters of the prenatal development. Our results revealed that the uterine horns typically had three-layered tunics, which became more distinct across the trimesters, with pseudostratified epithelial lining. In the first trimester, the right and left uterine horns had mescenchyme cells widely distributed within the connective tissue stroma. The second trimester had a slight indentation of future endometrial glands on the right uterine horn while the left horn had a distinct invagination on the epithelial lining. The organization of canalized endometrial glands at the third trimester were marked and more on the left than the right uterine horn with both primary and secondary longitudinal folds. Our findings are similar to those of other mammals in developmental strides. Our results provide new information on the histological features of the uterus in female Camelus dromedarius, an insight to reproductive management of this species of mammals.
