Regenerative medicine has entered a new era with
the development of modern science and technology.
The novel properties of chitosan make it one of the
most promising biopolymers for cell therapy, tissue
engineering and gene therapy. It is hoped that these
diverse approaches for regenerative medicine will
translate from ‘bench to bedside’ in the future. However,
efforts to improve the mechanical properties of
chitosan-based composite biomaterials are essential
for this type of application, especially the construction
of complex tissue and organs. The regulation mechanisms
for the interactions between different cell types
and chitosan material must be seriously addressed.
Moreover, majority of studies carried out thus far are
only in in vitro conditions and more in vivo studies
need to be carried out.
