Expression of Frzb-1 during chick development.

摘要: Abstract We cloned the chick homolog of Xenopus and mouse Frzb-1, a secreted Wnt antagonist performed in situ hybridisations to determine pattern cFrzb-1 expression developing embryo. At early stages, transcripts are located exclusively ectodermal layer corresponding neural plate. The labelling continues tube, but is always excluded from floor mRNA expressed by migrating cephalic truncal crest cells. Later, found subset derivatives such as cartilage, nerves spinal ganglia. In addition derivatives, were also observed mesodermal vertebral limb adrenal cortex, gonads, subpopulation blood
