Reciprocal Interactions Between Human GV-Oocytes and Cumulus Cells: Effects on GVBD, ROS Production, and AMPK Expression [PDF]
Background and Objectives: The quality of cumulus cells (CCs) is a major determinant of germinal vesicle (GV) oocyte maturation, yet the reciprocal effect of GV oocytes on cumulus cell function remains unclear.

Robotic Manipulation of Cumulus–Oocyte Complexes for Cumulus Cell Removal
The removal of cumulus cells from cumulus–oocyte complexes is a critical step in clinical in vitro fertilization. Since the oocyte is partially occluded by the surrounding cumulus cells and individual cumulus cells are small in size, it is difficult for ...

Multi-omics reveal the metabolic patterns in mouse cumulus cells during oocyte maturation [PDF]
Bi-directional communication between cumulus cells and the surrounded oocytes is important for the development and functions of both compartments. However, the metabolic framework in cumulus cells has not been systematically described.

The beneficial effects of cumulus cells and oocyte-cumulus cell gap junctions depends on oocyte maturation and fertilization methods in mice [PDF]
Cumulus cells are a group of closely associated granulosa cells that surround and nourish oocytes. Previous studies have shown that cumulus cells contribute to oocyte maturation and fertilization through gap junction communication.

Cumulus Cells and their Associations with Immune Functions
The recent progress in the association of cumulus cells with immune functions is a largely ignored area. With over 350 million new sexually transmitted infections occurring annually in adults of reproductive age, we feel the need to explore more about ...

Changes in the transcriptomic profile of cumulus cells under the influence of cumulus-oocytes complex pre-incubation. [PDF]
Pre-incubation of the cumulus-oocyte complex (COCs) may lead to better function of cumulus cells (CCs) and higher oocyte quality by changing the transcriptomic profile of CCs. 140 cumulus cell samples were isolated from 12 participants and divided into two groups based on pre-incubation time.

Cumulus Cells Are Potential Candidates for Cell Therapy [PDF]
Cumulus cells (CCs) originate from the membrane granulosa cells and surround oocytes during follicle maturation. CCs produce high levels of hyaluronan that targets CD44, which is a major tumorigenic marker. This study aimed to investigate whether CCs have a role in cell therapy by targeting CD44 in pancreatic cancer cells.CCs were isolated from the ...
