On his NSF grant. On his research using neural crest transplantation. Inquiry for letters of recommendation.
On his grant proposal (probably NSF). On his lecture plans.
On his grant proposal (probably NSF). On his lecture plans.
On the drafts of two separate papers on the development of sympathetic projections and on the distribution of fibronection. On explanting tissues in culture and presenting them with sympathetic preganglionic neurons.
Short note on NGF findings.
On references to neural crest migration.
On the guidance cues underlying sympathetic preganglionic projections.
On his sucessful NSF grant application. On possible effects of NGF on neuronal proliferation.
On transplanting single segments of the quail neural tubetogether with the overlying neural crest into chick embryos to study the migration of neural crest cells that form sympathetic chain ganglia.
Letter accompanying two diagrams by Yip on cell degeneration.
On Hamburger's argument that DM neuroms innervate the limbs exclusively. On a paper by Yip related to NGF.
On his paper on fibronectin publsihed in Developmental Brain Research. On his upcoming paper on axonal guidance in the sympathetic system of the chick, dedicated to Hamburger. On his ongoing research on guidance cues.
