From: Control of cell migration in the development of the posterior lateral line: antagonistic interactions between the chemokine receptors CXCR4 and CXCR7/RDC1

Figure 4

Early expression of cxcr7. A: no expression can be detected in the placode or in the primordium that begins to elongate towards the first somite at 20 hpf. B: expression can first be detected in trailing cells (arrow) when the primordium begins to extend along the myoseptum. C: expression increases (arrow) as the primordium extends along somites 1–3.
