Application and prospect of growth factors in clinical transplantation of tissue engineering trachea / 国际外科学杂志

ABSTRACT

Tissue engineering provides an effective treatment for tracheal reconstruction. The key to maintain airway function and ensure long-term survival of tracheal grafts is how to achieve epithelial cell regeneration, chondrocyte regeneration, and angiogenesis of the transplanted trachea. Growth factors are signaling molecules that direct cell development by providing biochemical cues for stem cell proliferation, migration, and differentiation. They play an important role in tissue engineering trachea regeneration. It is particularly important to design a delivery system that provides optimal activity, stability and adjustability for growth factors. This article summarizes the types, characteristics, functions of growth factors applied in the field of tissue engineering trachea, and the value of growth factors in tissue engineering trachea orthotopic transplantation aimed for promoting clinical transformation of tissue engineered trachea.
