ABSTRACT

BACKGROUND:

Compared with traditional hydrogels, intel igent hydrogels can appear to exhibit different responses to different stimuli such as temperature, pH value, light, and magnetic field, produce two-stage structure and alter chemical structure to generate the ordered supramolecular structure by self-assembling, and ultimately cause the formation of the gel with three-dimensional structure.

OBJECTIVE:

To review the research status of intel igent hydrogels and its application in tissue engineering.

METHODS:

A computer-based search of CNKI and PubMed databases was performed to retrieve articles addressing intel igent hydrogels in tissue engineering published before 2014. The keywords were“hydrogel, tissue engineering”in Chinese and English. RESULTS AND

CONCLUSION:

Intel igent hydrogels are classified into temperature sensitivity, pH sensitivity, photosensitivity, magnetic susceptibility and temperature/pH dual responsive hydrogels. The change of the external environment can be automatical y detected and responded. Intel igent hydrogels exhibit a series of outstanding performances in drug delivery systems, drug delivery, repair and improvement of defected tissues, which are not possessed by traditional materials. In particular, the intel igent hydrogels show considerable superiorities in tissue engineering, including low immunogenicity that reducing inflammation and rejection, biodegradability, realizing the three-dimensional scale simulation of cel microenvironment that is conducive to cel adhesion, growth, migration and differentiation.
