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 …
