The ability to generate well-defined gradients in cell density on engineered scaffolds is critical to the regeneration of many types of tissues. Herein we describe a simple and versatile method for generating gradients in cell density on glass slides and nonwoven mats of electrospun nanofibers. By inserting a glass slide (without or with a mat of nanofibers on the surface) into a suspension of cells at a tilt angle, a gradient in cell density along the direction of insertion can be established on the top surface of the glass slide due to the variation in the number of cells available for sedimentation. Different gradients in cell density can be readily obtained by simply varying the tilt angle. This method can also be applied to generate reverse gradients on the same substrate with two different cell types, which may find potential use in interface tissue engineering.
