“…Equating the dissipation rate with the rate of work of the drag force then implies that ∆C W Du is proportional to L −3 R . Figure 11 compares the predictions provided by expressions ( 27) and (28) with the numerical data obtained throughout the Rerange investigated. Obviously none of them is appropriate in the intermediate range 20 Re 100.…”

“…Numerical studies of hydrodynamic forces in near-wall configurations are quite scarce, presumably because they demand accurate boundary-fitted grids or refined immersed boundary techniques to properly capture the flow within the wall-particle gap. Variations of the slip-and shear-induced drag and lift forces in the low-but-finite Reynolds number regime with the wall located in either region of the disturbance were recently explored for both neutrally buoyant particles [28] and arbitrarily buoyant particles [29]. The characteristics of the slip-induced lift force in a wall-bounded fluid at rest were examined in detail in [16] and [17] down to small gaps and from Reynolds numbers of O(1) up to a few hundred.…”

“…As the Reynolds numbers are almost small in the creeping flow regime, a particle rotation and the Magnus lift force exerted on it can be ignored, and the drag (resistance) force in Stokesian form can be used 59 . In the Stokes limit, the lift force, an inertia-induced force, reduces to zero 60 . The Stokes law for calculating the Stokes drag force is shown in Eq.…”

It has been proved that cell-imprinted substrates molded from template cells can be used for the re-culture of that cell while preserving its normal behavior or to differentiate the cultured stem cells into the template cell. In this study, a microfluidic device was presented to modify the previous irregular cell-imprinted substrate and increase imprinting efficiency by regular and objective cell culture. First, a cell-imprinted substrate from template cells was prepared using a microfluidic chip in a regular pattern. Another microfluidic chip with the same pattern was then aligned on the cell-imprinted substrate to create a chondrocyte-imprinted-based integrated microfluidic device. Computational fluid dynamics (CFD) simulations were used to obtain suitable conditions for injecting cells into the microfluidic chip before performing experimental evaluations. In this simulation, the effect of input flow rate, number per unit volume, and size of injected cells in two different chip sizes were examined on exerted shear stress and cell trajectories. This numerical simulation was first validated with experiments with cell lines. Finally, chondrocyte was used as template cell to evaluate the chondrogenic differentiation of adipose-derived mesenchymal stem cells (ADSCs) in the chondrocyte-imprinted-based integrated microfluidic device. ADSCs were positioned precisely on the chondrocyte patterns, and without using any chemical growth factor, their fibroblast-like morphology was modified to the spherical morphology of chondrocytes after 14 days of culture. Both immunostaining and gene expression analysis showed improvement in chondrogenic differentiation compared to traditional imprinting methods. This study demonstrated the effectiveness of cell-imprinted-based integrated microfluidic devices for biomedical applications.
