What is a key feature of the fibroplastic phase of wound healing?

The fibroplastic phase of wound healing is primarily characterized by the formation of granulation tissue. This phase occurs after the inflammatory phase and is crucial for the repair of damaged tissue. During fibroplasia, fibroblasts proliferate and migrate to the wound site, where they synthesize collagen and other extracellular matrix components that provide structural support. Granulation tissue is distinguished by its rich supply of new capillaries, which facilitates nutrient delivery and oxygenation, and its characteristic pink or red appearance due to the vascularization.

Re-epithelialization does occur during the wound healing process but is more prominently associated with later stages of healing, particularly when the granulation tissue is being covered by new epithelial cells. Vascular contraction, while important in the wound healing process, does not define the fibroplastic phase specifically. Lastly, infection control is a critical component of overall wound management at all stages but is not a direct feature attributed to the fibroplastic phase itself. Thus, the formation of granulation tissue stands out as the essential element of this stage in the wound healing process.
