One fundamental aspect of vertebrate embryonic development is the formation of the body plan. For this process, asymmetries have to be generated during early stages of development along the three main body axes: Anterior-Posterior, Dorso-Ventral and Left-Right. We have been studying the role of a novel class of molecules, the Cerberus/Dan gene family. These(More)
During early mouse development, the TGFbeta-related protein Nodal specifies the organizing centers that control the formation of the anterior-posterior (A-P) axis. EGF-CFC proteins are important components of the Nodal signaling pathway, most likely by acting as Nodal coreceptors. However, the extent to which Nodal activity depends on EGF-CFC proteins is(More)
Body skeletal muscles formation starts with somite differentiation, due to signals from surrounding tissues. Somite ventral portion forms the sclerotome while its dorsal fraction constitutes the dermamyotome, and later the dermatome and myotome. Relative levels of BMP activity have been proposed to control several aspects of somite development, namely the(More)
Gonadotropin releasing hormone (GnRH) is a multifunctional decapeptide that possess endocrine as well as neuromodulatory roles and is present in all vertebrates. Endocrine GnRH cells play a crucial role in the establishment of the hypothalamic–pituitary– gonadal axis in many species. Recent studies have found that the prokineticin2 (pk2) and prokineticin(More)
