Gametogenesis, the process of forming mature germ cells, is an integral part of both an
individual's and a species' health and well-being. This chapter focuses on critical male and …

The evolution of gene expression in mammalian organ development remains largely
uncharacterized. Here we report the transcriptomes of seven organs (cerebrum, cerebellum …

Sexual fate can no longer be considered an irreversible deterministic process that once
established during early embryonic development, plays out unchanged across an …

Collective cell migration is the coordinated movement of a physically connected group of
cells and is a prominent driver of development and metastasis. Interactions between cells …

The gonadal development of the characin Astyanax aff. bimaculatus from Funil Reservoir, an
impoundment in the middle reaches of the Paraiba do Sul River in southeastern Brazil was …

In vertebrates, estrogen receptors are essential for estrogen-associated early gonadal sex
development. Our previous studies revealed sexual dimorphic expression of estrogen …

Dorsal mesentery and gonad (ovary and testis) are formed in distinct regions of the body
and have different characteristics. Recent studies using chicken embryos showed that …

Phenotypic plasticity is the ability of organisms with a given genotype to develop varied
phenotypes under fluctuating environmental conditions. This chapter provides an overview …

Abstract Development and differentiation of the reproductive system in lizards begin in the
embryonic period, although the stage and time of their occurrence vary according to …

DNA methylation is an epigenetic mark critical for vertebrate development and is associated
with numerous cellular and organismal processes including X-chromosome inactivation …
