Before revision:  However, the resulting bioreactors frequently lack information on intrinsic shear stress and flow distributions . Recent studies have focused on optimizing the microstructural parameters of the scaffold to gain more control over the shear stress.
After revision:  However, the resulting bioreactors frequently lack information on intrinsic shear stress and flow distributions . Recent studies have focused on optimizing the microstructural parameters of the scaffold to fine tune the shear stress.
