Sweet cues: How heparan sulfate modification of fibronectin enables growth factor guided migration of embryonic cellsKaren Symes
Department of Biochemistry, Boston University School of Medicine Boston, MA, USA
Cell Adh Migr 4:507-10. 2010..A model based on this observation is discussed here as well as the possibility that other growth factors/morphogens utilize similar mechanisms involving fibronectin or additional ECM proteins...
PDGF-A interactions with fibronectin reveal a critical role for heparan sulfate in directed cell migration during Xenopus gastrulationErin M Smith
Department of Biochemistry, Boston University School of Medicine, 72 East Concord Street, Boston, MA 02118, USA
Proc Natl Acad Sci U S A 106:21683-8. 2009..4). We further demonstrate that endogenous HSPG's are required for the PDGF-AA-guided mesendoderm movement, suggesting an in vivo role for HSPGs in mediating the interaction between PDGF-AA and fibronectin...
A role for CK2alpha/beta in Xenopus early embryonic developmentIsabel Dominguez
Hematology Oncology Section, Department of Medicine, Boston University Medical School, Boston, MA, USA
Mol Cell Biochem 274:125-31. 2005..Our results demonstrate that CK2 is required for dorsal axis formation and is for normal upregulation of Wnt signaling genes and targets. Thus, CK2 is a regulator of endogenous axis formation in vertebrates...
Protein kinase CK2 is required for dorsal axis formation in Xenopus embryosIsabel Dominguez
Section of Hematology Oncology Department of Medicine, Boston University School of Medicine, Boston MA 02118, USA
Dev Biol 274:110-24. 2004..Taken together, these studies demonstrate that CK2 is a bona fide member of the Wnt pathway and has a critical role in the establishment of the dorsal embryonic axis...
Distinct effectors of platelet-derived growth factor receptor-alpha signaling are required for cell survival during embryogenesisMelanie Van Stry
Department of Biochemistry, Boston University School of Medicine, 715 Albany Street, Boston, MA 02118, USA
Proc Natl Acad Sci U S A 102:8233-8. 2005..Furthermore, we demonstrate that small molecule inducers of dimerization provide a powerful system to manipulate receptor function in developing embryos...
Apoptosis regulates notochord development in XenopusMarina A Malikova
Department of Biochemistry, Boston University School of Medicine, Boston, MA, USA
Dev Biol 311:434-48. 2007..These data indicate that apoptosis is required for normal notochord development during the formation of the anterior-posterior axis, and its role in this process is discussed...
Migrating anterior mesoderm cells and intercalating trunk mesoderm cells have distinct responses to Rho and Rac during Xenopus gastrulationRuiyi Ren
Department of Biochemistry, Boston University School of Medicine, 715 Albany Street, Boston, MA 02118, USA
Dev Dyn 235:1090-9. 2006..Rho alone, however, regulates the retraction of the lagging edge of the cell. We propose that within the gastrulating Xenopus embryo, two types of mesoderm cells that undergo different motilities have distinct responses to Rho GTPases...
Distinct functions of Rho and Rac are required for convergent extension during Xenopus gastrulationEmilios Tahinci
Department of Biochemistry, Boston University School of Medicine, 715 Albany Street, Boston, MA 02118, USA
Dev Biol 259:318-35. 2003..We propose that Rho and Rac operate in distinct signaling pathways that are integrated to control cell motility during convergent extension...
Guidance of mesoderm cell migration in the Xenopus gastrula requires PDGF signalingMartina Nagel
Department of Zoology, University of Toronto, 25 Harbord Street, Toronto, Ontario M5S 3G5, Canada
Development 131:2727-36. 2004..This is consistent with an instructive role for PDGFA in the guidance of mesoderm migration...
The mitochondrial-apoptotic pathway is triggered in Xenopus mesoderm cells deprived of PDGF receptor signaling during gastrulationMelanie Van Stry
Boston University School of Medicine, Boston, MA 02118, USA
Dev Biol 268:232-42. 2004..Based on these data, we propose that PDGFR signaling is necessary for survival of prospective head mesoderm cells, and also plays an essential role in the control of their cell movement during gastrulation...
