T here is a vast clinical need for human serum albumin (HSA) with nearly 500 metric tons used worldwide every year. Currently, HSA is isolated from donated human blood/plasma, a source that fluctuates unpredictably and can potentially spread pathogens from donor to recipient. One solution to the problem is the use of transgenic cattle as living bioreactors, enabling large-scale production of recombinant HSA (rHSA) in a cost-effective manner. Previous simple bovine transgenics which express rHSA in the milk have not proved commercially viable due to the presence of endogenous bovine serum albumin (BSA), resulting in a prohibitively expensive and tedious purification process. Ultimately, this project intends to provide proof- of-principle for production of an inexpensive, reliable, and quality-controlled therapeutic source of rHSA through proposal of the following: 1) Replace endogenous BSA expression with rHSA expression using transcription activator-like effector nuclease (TALEN)-stimulated homologous recombination 2) Direct rHSA expression into the milk using a milk-specific alpha-lactalbumin promoter 3) Produce transgenic bovine embryos from modified fibroblasts using somatic cell nuclear transfer (SCNT)
