Chitosan and Its Potential Use as a Scaffold for Tissue Engineering in Regenerative Medicine
Table 1
Characteristics that must contain a biomaterial for use in tissue engineering and regenerative medicine.
Characteristics
Description of the characteristic
Biocompatibility
They must be accepted by the receptor and must not lead to rejection mechanisms because of its presence
Absorbability and degradability
Absorbable, with controllable degradation and resorption rate to be the same as the in vitro and in vivo cell/tissue growth
Not to be toxic or carcinogenic
Its degradation products cannot cause local or systemic adverse effect on a biological system
Chemically stable
Chemical modifications not being present in a biological system implant or biodegradable in nontoxic products, at least during the scheduled time to regenerate tissue
Chemically adequate surface
To have a chemically adequate surface for cell access, proliferation and cell differentiation
Adequate resistance and mechanical properties
Resistance and mechanical properties, superficial characteristics, fatigue time, and weight, according to the receptor tissue needs, as well
The proper design, size, and shape of the scaffolding
Which allows having a structure with properties according to the needs of the receiving tissue to regenerate or repair.
