Background: The production of transgenic animals has been envisioned as a viable strategy to improve food quality, animal yield, and for the production of bioproducts that can be used for the benefit of the human and animal population. Transgenic animals have been used to improve production traits, to add value to animal products, to minimize the impact on the environment, to promote disease resistance, and most notably, to produce recombinant proteins in natural fluids, such as milk, that can be collected, purified and used as biomedical products (biopharming). This review aims to discuss past and recent technological advances in animal transgenesis, and the perspective for biopharming in Brazil.Review: Since the production of recombinant human insulin from Escherichia coli in the 1970s, continuous development of new platforms has allowed a significant expansion in the biopharmaceutical market. The animal platform has been shown to be highly competitive by adding value as low cost implementation, production and scale up, as well as high productivity of synthesized proteins. The expression of recombinant proteins in milk represents the most developed system for production of biopharmaceutical drugs in animals, with two approved biopharmaceuticals for human use: Atryn®, a recombinant antithrombin produced in the milk of goats, approved in 2006 by European Medicines Agency (EMA) and in 2009 by US Food and Drug Administration (FDA), and more recently, Ruconest®, a recombinant human C1 esterase inhibitor protein (C1INH) produced in the milk of rabbits, first approved by EMA in 2012, followed by the FDA approval in 2014. Transgenic animals have been produced by many strategies that have gradually evolved over the decades, including the use of embryo microinjection, viral vectors and transposable elements, sperm-mediated gene transfer, and cloning by somatic cell nuclear transfer (SCNT).[...](AU)
