Abstract
The development of biomaterials in tissue engineering has already started
decades ago. A wide variety of biomaterials are being used as alternatives in clinical
applications. Lately, animal by-products have increased in demand for natural
substrates in various sectors. As in tissue engineering, animal-based biomaterials are
from different resources or origins of animal species that are being studied and applied
for disease treatments. In addition to this, novel biomaterials are being produced that
could imitate the physiology of natural healing mechanisms or the regeneration of
certain tissues. Thus, the efficiency in utilising animal by-products could alleviate the
waste management cost and scarcity of materials, which could reduce environmental
pollution. This book chapter discusses different classifications of animal byproducts,
their unique characteristics, and the advantages of these products that could embark as
new alternative approaches for treating diseases.
