Measurements of the diameters of the great arteries and semi-lunar valves of chick and mouse embryos.

29 Apr 2009 The great arteries of embryos are small channels of a complex three-dimensional arrangement. Measurements of their diameters, as required for understanding cardiovascular morphogenesis and the genesis of malformations, cannot be performed in ... Read more...

Identification and characterization of aortic valve mesenchymal progenitor cells with robust osteogenic calcification potential.

11 Feb 2009 Advanced valvular lesions often contain ectopic mesenchymal tissues, which may be elaborated by an unidentified multipotent progenitor subpopulation within the valve interstitium. The identity, frequency, and differentiation potential of the ... Read more...

Stress related collagen ultrastructure in human aortic valves--implications for tissue engineering.

10 Aug 2008 Understanding the response of tissue structures to mechanical stress is crucial for optimization of mechanical conditioning protocols in the field of heart valve tissue engineering. In heart valve tissue, it is unclear to what extent mechanical ... Read more...
