Question

Quizplus · Accepted Answer

Fibronectin is an extracellular matrix protein that serves as an adhesive surface for cells to migrate on and provides anchorage for cells during gastrulation in frog embryos. It helps in the formation of the primitive streak, a structure essential for the establishment of the three germ layers of the embryo.
