Which process marks the start of scar tissue formation during wound healing?

• A. Granulation tissue formation
• B. Epithelialization
• C. Hemostasis
• D. Inflammation

Answer: (A)

Scar tissue formation starts during the repair phase when granulation tissue forms. This stage brings in fibroblasts that lay down collagen and new capillaries, creating a soft, vascular scaffold in the wound. That scaffold is what later remodels into stronger connective tissue, leading to scar formation. While inflammation cleans up debris and epithelial cells begin to cover the wound, the actual start of scar tissue development is the appearance of granulation tissue. Hemostasis stops bleeding earlier and does not initiate scar formation.
