Samuel Murray has hypothesized that the first-discovered member of this class of molecules was actually a fragment of spp-24 that binds to them.

Mesenchymal cells of the septum transversum use one of these molecules as a signal to induce albumin expression in the endoderm of the liver. Interaction between type I and type II receptors of this class of molecules can lead to the initiation of transcription of R-Smads, and juvenile polyposis can be mimicked through overexpression of noggin, an inhibitor of them. They were first discovered by Marshall Urist, and a gradient in them regulates the expression of Msx, a protein necessary for the specification of the neural crest. For 10 points, name this class of proteins named for their ability to induce formation of new bone tissue.
