Yоur teаm in а biоengineering lаb is tasked with engineering a replacement trachea fоr a patient with congenital tracheal stenosis. To achieve this, your team decellularize an allogeneic trachea and seed it with the patient derived cells as shown in the diagram below. The goal is for the MSCs to differentiate into chondrocytes to form the tracheal cartilages. Unfortunately, the implant collapsed 1 week after implantation into the patient and is removed. 1. Could better in vitro staging of the engineered trachea have prevented the collapse and why? (4 points) 2. Your team decides to add a bioactive factor to the culture. What behavior of the MSCs would you recommend for the bioactive factor to modulate and why? (4 points)
