Fig. 7. Co-expression of Fgfr3 and glutamine synthetase (Glns) in
the VZ and parenchyma of the embryonic mouse spinal cord. There was
considerable overlap between the in situ hybridisation signals for
Fgfr3 and Glns in the E15 mouse spinal cord, strongly
suggesting that Fgfr3+ cells correspond to glial
(presumably astrocyte) precursors. Arrows indicate cells that express both
Fgfr3 and Glns.
