Tissue engineering advantages

Table 1 Advantages and disadvantages of hydrogels as tissue engineering matrices Advantages Aqueous environment can protect cells and fragile drugs (peptides,...

Implantable tissue-engineered constructs are derivatives of cell therapies. They have certain advantages over implanting cells in that the culturing process is more easily controlled and tested before risking implantation. The technique is highly experimental and not without problems. We cover this more completely in later sections. 

Microporous polymers have been used in the intensification of several processes encountered in nuclear, petroleum, bioconversion, tissue engineering, chemical, and environmental technologies. The advantages of PHP and its metallic form are associated with the accessibility of their pores, controllability of the pore and interconnect structures, versatility of fabrication, and chemical modification of their walls. The structure of these materials is shown in Figs. 6A-C. These polymers can be manufactured over a wide range of pore size (D) (0.5 pm < D < 5000 pm) and interconnect size (D) (0 < d/D < 0.5). 

Grafted chitosans have great utility in controlled drug release [115], tissue engineering [116], wound-healing [117] and cardiovascular applications [118-119]. Moreover, there are several reports regarding the use of enzymes in polymer s)m-thesis and modification [120-121]. In fact, enz)mies offer the potential advantage...
