The phrase "a key cell" is correct and usable in written English.
It can be used in contexts related to biology, data analysis, or any situation where a specific cell is crucial to understanding a larger system or dataset.
Example: "In the experiment, a key cell was identified that played a significant role in the overall reaction."
Alternatives: "a crucial cell" or "an essential cell".
Activation of the IDO-Kyn-AhR cascade upregulates the expression of p27, a key cell cycle inhibitor.
MSCs normally lack a key cell surface adhesion molecule called HCELL, which mediates the homing of cells in the bloodstream to sites of tissue inflammation.
Activation of the phospholipase A2 (pathwayathway is a key cell signaling event in the inflammatory response.
CDK1 (p34) has been reported to be closely involved in both regeneration and development of hair cells in the cochlea, a key cell cycle process required to replenish hair cell populations for efficient hearing30.
These vaccines enhance the body's immune response to cancerous cells, and dendritic cells (DCs), an initiator of adaptive immunity, are a key cell type targeted by these strategies.
The podocyte is a key cell in the glomerulus in health and disease: until recently, human podocytes have been difficult to study in vitro.
They discovered, for example, that the saliva of Ixodes scapularis prevents the division of T cells--a key cell in the immune system--but how this occurred wasn't clear.
The UC Berkeley bioengineers found that viral infections turn down the intensity of a key cell-signaling pathway linked to healing and health of skeletal muscle and bone, mental well-being and prevention of obesity.
