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 within the scaffold. Consequently, it is difficult to interpret the effects of shear stress on cell function. Such knowledge would enable researchers to improve upon cell culture protocols. Recent work has focused on optimizing the microstructural parameters of the scaffold to gain more control over the shear stress.
