Proximal Ascending aorta is made of #SmoothMuscleCell of dual lineage origins
Luminal side: Wnt1+ #CardiacNeuralCrest
Abluminal side: Mef2c+ #SecondHeartField

Amazing - Human Aortas can be cryopreserved at -80 °C with 10% DMSO for 12 months with histological (elastin, SMC, EC) & mechanical (subfailure stress, max stress, low/high stretch moduli) integrity largely retained
