The expression of plasmid DNaseI gene in mice bone marrow mesenchymal stem cells / 中华风湿病学杂志

ABSTRACT

Objective To investigate the expression and secretion of mice DNaseI gene plasmid transfected into bone marrow (BM-MSCs) mesenchymal stem cells. Methods The plasmids of mouse DNaseI gene had been transfected into the BM-MSCs of mice by liposomes. The expression of DNaseI gene in the BM-MSCs was detected by western blotting and the DNaseI activity was measured by DNA-methyl green substrate colorimetry. Results About 30% BM -MSCs were transfected with mice plasmid DNaseI gene, DNaseI was expressed in the transfected BM-MSCs and active DNaseI could be detected in the supernatant of cell culture. Conclusion The mice DNaseI gene plasmid can be transfected into mice BM -MSCs by liposomes and DNaseI gene can be expressed by the transfected BM-MSCs and active DNaseI can be secreted. This may provide potential target for the treatment of SLE.
