- collagen

Answer 1

Fibronectin is the most instrumental factor in the migration of fibroblasts into the area of wound healing.

Step-by-step explanation:

The most instrumental factor in the migration of fibroblasts into the area of wound healing one week after the sutures are removed is fibronectin. Fibronectin is a glycoprotein that is secreted by fibroblasts and is involved in cell adhesion and migration. It helps to create a scaffold for the fibroblasts to move on and promotes their migration into the wound site.
