Hydrogels in Gene Delivery Techniques for Regenerative Medicine and Tissue Engineering

Abstract

Hydrogels are three‐dimensional networks swollen with water. They are biocompatible, strong, moldable, and are emerging as a promising biomedical material for regenerative medicine and tissue engineering to deliver therapeutic gene. The excellent natural extracellular matrix simulation properties of hydrogels enable them to be co‐cultured with cells or enhance the expression of viral or non‐viral vectors. Its biocompatibility, high strength and degradation performance also make the action process of carriers in tissues more ideal, making it an ideal biomedical material. It has been shown that hydrogel‐based gene delivery technologies have the potential to play therapy‐relevant roles in organs such as bone, cartilage, nerve, skin, reproductive organs, and liver in animal experiments and preclinical trials. This paper reviews recent articles on hydrogels in gene delivery and explains the manufacture, applications, developmental timeline, limitations, and future directions of hydrogel‐based gene delivery techniques.This article is protected by copyright.
