Title: Peggy Winters-Digiacinto: Innovator in Transgenic Technology

Introduction

Peggy Winters-Digiacinto is a notable inventor based in Foster City, CA (US). She has made significant contributions to the field of biotechnology, particularly in the area of transgenic chickens. Her innovative work has implications for the production of proteins in avian species.

Latest Patents

Winters-Digiacinto holds a patent for "Tissue specific expression of exogenous proteins in transgenic chickens." This patent describes a method where transgenes encoding exogenous proteins are stably integrated into embryonic stem cells. These transgenes are present in the somatic tissue of transgenic or chimeric birds. The technology allows for the expression of exogenous proteins in various tissue types, including endodermal, ectodermal, mesodermal, or extra embryonic tissue. The specificity of tissue expression is achieved by selecting the content of the transgene accordingly. Notably, transgenic birds can express exogenous proteins in the tubular gland cells of the oviduct, concentrating these proteins in egg white.

Career Highlights

Throughout her career, Winters-Digiacinto has worked with several prominent companies, including Origen Therapeutics, Inc. and Synageva Biopharma Corporation. Her experience in these organizations has contributed to her expertise in biotechnology and transgenic research.

Collaborations

Winters-Digiacinto has collaborated with notable professionals in her field, including Lei Zhu and Robert Etches. These collaborations have furthered her research and development efforts in transgenic technology.

Conclusion

Peggy Winters-Digiacinto is a pioneering inventor whose work in transgenic chickens has the potential to revolutionize protein production in avian species. Her contributions to biotechnology are significant and continue to influence the field.
