Gene editing technologies, such as CRISPR-Cas9, have important applications in mammalian embryos for generating novel animal models in biomedical research and lines of livestock with enhanced production traits. However, the lack of methods for efficient introduction of gene editing reagents into zygotes of various species and the need for surgical embryo transfer in mice have been technical barriers of widespread use. Here, we described methodologies that overcome these limitations for embryos of mice, cattle, and pigs.

Spermatogonial stem cells (SSC) are the most undifferentiated germ cell present in adult male testes and, it is responsible to maintain the spermatogenesis. Age has a negative effect over stem cell, but the aging effect on SSC is not elucidated for bovine. The present study aim to evaluate the effect of age on the expression of undifferentiated spermatogonial markers in testis and in enriched testicular cells from prepubertal calves and adult bulls.
