Abstract

Avian species serve as vital resources in human society, with the preservation and utilization of these species heavily reliant on primordial germ cells (PGCs). However, methods for effectively isolating these rare cells alive from embryos remain elusive in avian species beyond chickens. Even within chicken species, existing techniques have shown limited efficiency. In our study, we present a rapid, simple, and cost-effective method for labeling and sorting circulating-stage PGCs across various avian species, including Carinatae and Ratitae, utilizing Lycopersicon Esculentum lectin. Significantly, this method demonstrates high sorting efficiency by identifying a wide range of PGC subtypes while preserving the proliferative potential of chicken PGCs. This approach is anticipated to make a significant contribution to the conservation, research, and agricultural industries related to birds worldwide.
