mRNA has the potential to be the next generation drug for tissue restoration in regenerative medicine. The variety of mRNAs that could be synthesized with the aim of increasing the expression of any required protein offers new opportunities. However, the intrinsic immunogenicity and lack of stability of mRNA has long restricted the potential of mRNA therapeutics. Fortunately, considerable progress has been made on synthetic mRNA modifications and relevant purification steps that have overcome these limitations. However, there remains a lack of efficient mRNA delivery strategies. Additionally, mRNA may need to be administered in situ via three-dimensional biomaterials. These materials, also known as transcript-activated matrices, require further consideration in terms of mRNA loading and release, immunogenicity, and other features. In this article, various limiting factors in mRNA synthesis, vector formulation, and local delivery to tissues are highlighted together with current developments and the future outlook for mRNA therapeutics in tissue regeneration.
