Hi, Medlibbers! I hope somebody out there can help me with this citation. I think sometime between Sept. 1995 and now, an article entitled "Expression of bone morphogenetic protein-4(BMP-4), bone morphogenetic protein-7(BMP-7), fibroblast growth factor (FGF-8), and sonic hedgehog during branchial arch development in the chick" was published in Mechanisms of Development. The author is Nancy A. Wall. It is not indexed in Medline. Could somebody who subscribes to this journal please check and send me the full citation? TIA. -- Ellen Dewkett Voice: (864) 388-1708 Greenwood Genetic Center Fax: (864) 388-1808 1 Gregor Mendel Circle E-mail: [log in to unmask] Greenwood, SC 29646
