In the second paragraph of “Theoretical calculation of the pressure and shear stress in the deformed macrochannel” in “RESULTS AND DISCUSSION,”1 the text “Due to the cell culture medium container connecting to the atmosphere, (Pout) at the outlet of the deformed macrochannel can be calculated from the pressure drop of the tubes connecting the outlet to the container, which concludes the pressure head loss (ΔPguide) in a narrow guide rectangular microchannel and that singledollar (ΔPextended) singledollar in an extended outflow round duct, …” should be corrected to “Due to the cell culture medium container connecting to the atmosphere, the pressure (Pout) at the outlet of the deformed macrochannel can be calculated from the pressure drop of the tubes connecting the outlet to the container, which concludes the pressure head loss (ΔPguide) in a narrow guide rectangular microchannel and the pressure head loss (ΔPextended) in an extended outflow round duct, ….”.
