Lineage study in control and mutant IVDs.

<p><b>A,B</b>. Detection of fluorescence in frozen sections of NP isolated from E15.5 (A) and 1 month (B) HIF-1α<sup>f/f</sup> (a,e,i), HIF-1α<sup>f/f</sup>;mTmG (b,f,j), Foxa2<sup>iCre</sup>;HIF-1α<sup>f/+</sup>;mTmG (c,g,k) and Foxa2<sup>iCre</sup>;HIF-1α<sup>f/f</sup>;mTmG (d,h,l) mice, respectively. Red fluorescence (a-d), green fluorescence (e-h) and merged filters (i-l) are shown. Bar = 100 µm.</p>
