The Evolution of Organ Shape : Distal Tip Cell Migration and Gonadogenesis in Nematodes
Animals display a variety of shapes in nature. The different shape of homologous organs allows them to adopt different functions and therefore, allows animals to live in different ecological niches. However, little is understood about the cellular and molecular mechanisms involved in the evolution …

A Mutation in Alk6b Causes Impaired Germ Cell Differentation and Testicular Germ Cell Tumors in Zebrafish
… development, germ cell specification and gonadogenesis. Misregulation of the BMP signaling pathway has been implicated in various human cancers. In agreement with a critical role for Alk6b in controlling germ cell differentiation, we find evidence of impaired BMP signal transduction in the …

BMP Signaling Regulates Germ Cell Pluripotency, Sexual Differentiation, and Cancer Susceptibility
… bmp2b, bmp7a or smad5 have profoundly impaired gonadogenesis and altered male:female sex ratios. Affected fish also exhibit markedly abnormal gonadal differentiation, including the presence of undifferentiated gonadal tissue and the occurrence of biphenotypic gonads, as well as greatly increased …

Lake Sturgeon (Acipenser fulvescens) Population Attributes, Reproductive Structure, and Distribution in Namakan Reservoir, Minnesota and Ontario
… ranged from 3.2 to 24.0 km) and may be linked to gonadogenesis (e.g., increased energy acquisition) prior to spring spawning. A link between migration distance and female reproductive condition may have implications for lake sturgeon conservation particularly in water bodies that have experienced …
