Apoptosis and Remodeling in Ovary of Water Deer and Sika Deer at Pregnant and Non-pregnant Stages

Background: Many studies have been conducted on the sika deer, an extinct species in Korea, to analyze physiological characteristics of restoration and reproductive characteristics. The mechanisms water deer especially function, morphological changes, ovarian characteristics, are unknown. Objective: We aimed study differences physiology determine difference function through analysis cell remodeling. Methods: Water ovaries were collected during estrus pregnancy seasons from Korean Peninsula Russia–Korean border, respectively, analyzed. Morphological situ zymography confirm activity matrix metalloproteinases (MMPs), immunofluorescence Casp-3 protein, assess changes ovaries. Results: results confirmed be morphologically different. corpus luteum showed large size morphology compared many also observed cells. However, MMPs apoptosis follicles higher than those deer. similar patterns pregnancy. Conclusion: In our study, found present between ovaries; however, remodeling demonstrated a pattern. Therefore, endocrine efficiency for reproduction would similar.
