1. (20 points) Lack of angiogenesis is a major problem in the use of tissue engineered scaffolds due to the inability for the tissue engineered scaffold to survive in the body. Your group is interested in directing angiogenesis through the use of growth factors embedded within a scaffold. In order to promote angiogenesis you will need to direct the migration of endothelial cells. Through research in journal articles you have narrowed down the possible growth factors that direct endothelial cells to two factors VEGF and FGF-2.

Answer b) please.

(b) Through time-lapse microscopy, you have received the following data for cell migration. Calculate the mean squared displacement for time point 2 for the control, VEGF and FGF2 cells. (only calculate ). (10 points) (b) Through time-lapse microscopy, you have received the following data for cell migration.
