Somite formation in the early chick embryo following grafts of Hensen's node.
نویسندگان
چکیده
Quail grafts of Hensen's node were examined for their potential to induce somites in chick blastoderms. The origin of the structures induced depended on the distance of the graft from the host's midline. Nodes placed at the margin of the area pellucida resulted in structures differentiated from the cells of the graft, whereas medially the graft organized host cells to form rows of somites. The results are discussed in terms of competence of graft and host mesenchyme and a positional signal from the node.

Commitment of mesoderm cells in Hensen's node of the chick embryo to notochord and somite
Hensen's node in the chick embryo contains prospective notochord cells in a V-shaped midline region of the mesoderm, and prospective medial half somite cells in the lateral portions of the node mesoderm, whilst lateral somite cells are derived from the rostral part of the primitive streak (Selleck and Stern, Development 112, 615-626, 1991). In the present study, we have investigated the commitm...
متن کاملStudies on effects of 5-bromodeoxyuridine on the development of explanted early chick embryos.
Chick embryos were explanted at stages ranging from the definitive streak to one-somite and cultured for 19-21 h on thin albumen with or without 5-bromodeoxyuridine (BrdU) (2-12/ig/ml). BrdU primarily inhibited neurulation which was found to be stage dependent. If exposed to BrdU at the definitive streak stage, it resulted in an open brain region; if treatment was delayed until the head-process...
متن کاملA spinal cord fate map in the avian embryo: while regressing, Hensen's node lays down the notochord and floor plate thus joining the spinal cord lateral walls.
The spinal cord of thoracic, lumbar and caudal levels is derived from a region designated as the sinus rhomboidalis in the 6-somite-stage embryo. Using quail/chick grafts performed in ovo, we show the following. (1) The floor plate and notochord derive from a common population of cells, located in Hensen's node, which is equivalent to the chordoneural hinge (CNH) as it was defined at the tail b...
متن کاملThe spatial and temporal distribution of polarizing activity in the flank of the pre-limb-bud stages in the chick embryo.
The presence of polarizing activity in the limb buds of developing avian embryos determines the pattern of the anteroposterior axis of the limbs in the adult. Maps of the spatial distribution and the strength of the signal within limb buds of different stages are well documented. Polarizing activity can also be found in Hensen's node in the early embryo. We have mapped the distribution of polar...
متن کاملFates and migratory routes of primitive streak cells in the chick embryo.
We have used carbocyanine dyes to fate map the primitive streak in the early chick embryo, from stages 3+ (mid-primitive streak) to 9 (8 somites). We show that presumptive notochord, foregut and medial somite do not originate solely from Hensen's node, but also from the anterior primitive streak. At early stages (4- and 4), there is no correlation between specific anteroposterior levels of the ...
