Abstract
Tissue plasminogen activator tPA play important roles in the brain after excitotoxic injury. This study was conducted to produce transgenic pig harboring human tissue plasminogene activator htPA gene. Recombinent htPA rhtPA genes containing mouse uroplakin promoter mUPIl were prepared for microinjection and testified the expression level of htPA protein from the Chinese hamster ovary CHO cell lines before DNA microinjection into the porcine pronuclei. Concentration of htPA expression from the six cell lines all of CHO cells were an average of212.4 ng/mI. Reconstructed DNA to use the CHO cells were microinjected into the pronuclei of in vivo derived porcine embryos. The 1 246 embryos microinjected with mouse uroplakin promoter-tPA were transferred to 55 recipients. Forty offspring from 6 sows were delivered. We analysed the transgenes with PCR methods from 40 piglet tails DNA and two of them were detected as transgenic pigs. This result show the potential of purified rh-tPA derived from transgenic pig urine could be used for the treatment of thrombus in humans.
