2.79J/3.96J/20.441J/HST522J Biomaterials - Tissue Interactions Homework #3 1. Write 3 unit cell processes that could occur in the acute phase of wound healing of a vascularized tissue, showing their interactions. 2. Write 2 unit cell processes that could occur during the chronic phase of wound healing, showing their interactions. 3. A major problem with joint replacement prostheses is polyethylene particle-induced degradation of bone (referred to as "osteolysis"; see Fig. 1). Write the unit cell process(es) to describe this phenomenon. Name possible regulators when they are known.

Unformatted text preview: Gazette showing the particles of polyethylene, generated by a wear process, infiltrating the tissue around a prosthesis. The area shown as “weakened bone” is a region where bone resorption has resulted from the response to the polyethylene particles. Figure by MIT OpenCourseWare.
