ABSTRACT

Ever since Langer and Vacanti introduced the concept of tissue

engineering [1], it has been a research field of high interest

due to the possibilities it offers in addressing tissue and organ

failure. Current treatments include administration of therapeutics,

reconstructive surgery, organ transplantation and implantation of

mechanical devices [1, 2]. However, these treatments have major

drawbacks such as adverse side effects, donor shortages, transplant

rejection and failure, mechanical failure as well as risks of major

immune responses [1, 2]. In comparison, tissue engineering aims

to address these issues via autologous regeneration or repair, to

restore, maintain or improve tissue function [1]. Amajor component

of tissue engineering research is the study and development of

scaffolds. Scaffolds are constructs that permit tissue regeneration

while providing a suitable environment and mechanical support

[3, 4]. The fundamental aim of tissue engineering involves seeding

patients’ cells that are harvested onto a suitable scaffold, whereby

the tissue ideally regenerates into a functional tissue in vitro or in

vivo (Fig. 5.1) which will then repair or restore the compromised

function.
