Disclosed herein are devices for use in transplanting cells. The devices can include a housing defining a cavity; and a support structure separating the cavity into a cell chamber and a reservoir chamber, wherein the support structure comprises a membrane for fluid communication between the cell chamber and reservoir chamber. The cell chamber can define a first opening comprising a microstructure containing an array of micro-channels, each having a diameter to facilitate growth of vascular tissues; and an array of micro-reservoirs, each having a diameter to facilitate housing of cell aggregates individually. The membrane can define a surface area that is at least 50% of a total surface area of the support structure. Methods of treating a subject for a disease condition, such as diabetes, are also disclosed.
