Crest-derived cells isolated from chick gut migrate
toward co-cultured netrin-1-expressing cells.
•
Stably transfected cells expressing netrin-1 were embedded in 3-D collagen gels.
Immunoselected crest-derived cells were plated over the gels.
•
Netrin-1 has a chemoattractive effect on immunoselected enteric crest-derived
cells in vitro.
