Task: Answer Verification
Input (English): Question: Does abnormal Shh and FOXC2 expression correlate with aberrant lymphatic development in human fetuses with increased nuchal translucency?
Answer: Increased Shh and VEGF-A expression is correlated with an aberrant lymphatic endothelial differentiation in trisomy 21 fetuses. The SMCs surrounding the JLS can possibly be explained by an increase of PDGF-B-induced SMC recruitment and/or differentiation. This underscores earlier findings that indicate the loss of lymphatic identity in trisomy 21 fetuses and a shift towards a blood vessel wall phenotype.
Output (English): yes
