ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the feasibility of establishing transgenic mice by means of seminiferous tubule microinjection and electroporation (EP) in vivo.</p><p><b>METHODS</b>Specific pathogen-free (SPF) male Kunming mice divided into 4 groups were subjected to microinjection of two different transfection solutions labeled with enhance green fluorescent protein (EGFP) into the seminiferous tubule of the testis, and in one of the two groups receiving the identical transfection solutions, EP in vivo was performed. After two weeks, the male mice of each group were mated with SPF female Kunming mice with superovulation treatment, and PCR coupled with Southern blotting was performed for the offspring mice.</p><p><b>RESULTS</b>The results of PCR suggested significant difference in the efficiency of exogenous gene integration between the 4 groups (P<0.01), among which group A achieved the greatest efficiency (45%). Southern blotting did not identify significant difference between the 4 groups (P>0.05), but still suggested the highest efficiency in group A (25%).</p><p><b>CONCLUSION</b>Seminiferous tubule microinjection in conjunction with subsequent EP in vivo can remarkably enhance the integration efficiency of exogenous genes into the host genome, but this new method needs to be further tested for its potential utility in transgenic animal generation.</p>
