Genome wide mRNA expression analysis of small and large luteal cells, isolated from the mature staged corpora lutea (CL), was not performed in any species. In the current study, we have isolated bovine small and large luteal cells from mid-cycle (day 10-11) animals and characterized their transcriptomes using "GeneChip™ Bovine Gene 1.0 ST Arrays". A total of 1276 genes were identified to be differentially expressed between small and large luteal cells. Data evaluation revealed that novel functions, extracellular matrix synthesis and immune cell recruitment, were enriched in small luteal cells. On contrary, functions regarding the regulation of folliculogenesis, luteal regression, fatty acid and branched chain amino acid metabolism were differentially enriched in large luteal cells. Overall, the current data offer a first and detailed insight into the functional roles of small and large luteal cells in the mature bovine corpus luteum.

The study aimed to establish a long-term 3D cell culture model using luteinized follicular cells to investigate the functionality and life cycle of the CL in felids. A mixture of cell types from antral follicles was luteinized in vitro and cultured for up to 23 days. The method, initially applied to the domestic cat, was later extended to Persian and Clouded leopards.

The embryonic diapause of the giant panda (Ailuropoda melanoleuca) has caused great difficulties in monitoring pregnancy in this vulnerable species. The secretion of prolactin (PRL) from anterior pituitary glandular lactotropic cells is an important signal for the termination of embryonic dormancy. Currently, the mechanism by which PRL affects embryonic diapause in giant pandas and methods for detecting PRL in this species are poorly understood.

AMPK plays a crucial role in cellular energy metabolism and is involved in the regulation of luteal steroidogenesis by APN and its analog AdipoRon. To further explore the regulatory mechanism of AMPK in goat luteal steroidogenesis mediated by APN, cyclic and pregnant CL were utilized to assess the localization and expression of AMPK, EZH2, H3K27me3 and H3K27ac by WB and mIHC, and the interaction between AMPK and EZH2 by Co-IP. Then, isolated luteal cells were treated with APN/AdipoRon to evaluate the expression levels of AMPK, EZH2, H3K27me3 and H3K27ac.

Objective: Female mice exhibit progressive progesterone (P4) deficiency, luteal cell degeneration, and premature embryo implantation failure at 5 months old. We attempted to rescue embryo implantation in non-virgin mice (5-6 months old) with exogenous P4 treatment on days 1.5 post-coitum (D1.
