Key result
Computational modeling of zebrafish embryos revealed elevated wall shear stress in wild type and AG1478 variants compared to gata1aMO and wea, with high oscillatory shear index in trabecular grooves.
A novel computational framework successfully quantified mechanobiologic forces in developing zebrafish hearts, suggesting oscillatory forces as a possible regulatory mechanism of cardiac trabeculation.

New framework quantifies forces in zebrafish heart development; leaves open translation to mammalian models or clinical relevance.
Vedula et al. (2017) studied Cardiac development. AG1478, gata1aMO, or wea mutation vs. Wild type zebrafish was evaluated on Wall shear stress and oscillatory shear index. Computational modeling of zebrafish embryos revealed elevated wall shear stress in wild type and AG1478 variants compared to gata1aMO and wea, with high oscillatory shear index in trabecular grooves.
