摘要

Non-viral gene delivery systems are important transport vehicles that can be safe and effective alternatives to currently available viral systems. A new family of multifunctional spider silk-based gene carriers was bioengineered and found capable of targeting human mesenchymal stem cells (hMSCs). These carriers successfully delivered DNA to the nucleus of these mammalian cells. The presence of specific functional sequences in the recombinant proteins, such as a nuclear localization sequence (NLS) of the large tumor (T) antigen of the Simian virus 40 (SV40 ), an hMSC high affinity binding peptide (HAB), and a translocation motif (TLM) of the hepatitis-B virus surface protein (PreS2), and their roles in mitigatio...
