Tissue Specific Porcupine Deletion Reveals A Novel Role For Ectodermal Wnts In Musculotendon Development, Aaron P. Smith
Tissue Specific Porcupine Deletion Reveals A Novel Role For Ectodermal Wnts In Musculotendon Development, Aaron P. Smith
Theses and Dissertations
The Wnt family of secreted proteins consists of 19 family members (in the mouse) and is known to signal through multiple pathways that regulate crucial processes in the development of almost all tissues. Dissecting the roles of individual Wnts has been hampered due to functional redundancy that exists between family members. We made use of a conditional allele of the acyltransferase, Porcupine (Porcn), that is required for the secretion of all Wnt ligands, and the Msx2Cre deleter to eliminate the secretion of all Wnt ligands from the ventral limb ectoderm, ventral abdominal ectoderm, and urogenital ectoderm. Phenotypically the …

The Role Of A And B Vitamins During Orofacial Development Of Xenopus Laevis, Allyson Kennedy
Theses and Dissertations
Orofacial anomalies make up about a third of the 120,000 birth defects each year in the United States. Children born with these abnormalities must undergo immense physical and emotional strain in order to correct the defects. In fact, about $697 million is spent every year surgically treating children with cleft lip and/or cleft palate (2011). In countries where surgery is not an option, this abnormality causes immense difficulties in eating, hearing, speech, and psychosocial development. The causes of cleft lip/palate are extremely complex. Genetics play a role in the anomaly; however, 95% of cleft palate cases are non-syndromic and likely …
