Fibrocytes are mature fibroblasts. But in some cases, fibrocytes can revert to fibroblasts. Based on their function, when would you expect a fibrocyte may revert to a fibroblast?

• A. A fibrocyte may revert to a fibroblast as a normal aging process as the cells become less active over time.
• B. A fibrocyte may revert to a fibroblast in the case of significant tissue injury/damage to produce new ECM.
• C. A fibrocyte may revert to a fibroblast in order to store energy in the form of lipids.
• D. A fibrocyte may revert to a fibroblast during an acute infection as fibroblasts provide direct immune protection against pathogens.
