Abstract

The Smart Multi-Well Plate (SMWP), an open technology platform for Organ-on-Chip (OoC) technology developed as part of the Moore4Medical (M4M) consortium, aims to showcase the advantages of standardization in design, manufacturing and assembly for OoC [1]. In previously presented work [2], we showed integration and characterization of piezoelectric micropumps for in-line perfusion of OoC devices. Here we present the integration and preliminary biological evaluation of three OoC devices in a SMWP prototype. This prototype, a downscaled version of the full SMWP, is constructed using stacked, predefined layers. The reservoirs of a 96-well plate are fluidically connected to integrated OoC devices and micropumps through a fluidic circuit board (FCB). A printed circuit board, assembled below the FCB, enables the electrical interfacing. The following devices were integrated in the prototype: OoC devices from Bi/ond and BEOnChip, a microelectrode array (MEA) device from MultiChannel Systems, and piezoelectric micropumps from Fraunhofer EMFT. In the OoC devices, cell culture was performed on integrated on-chip membranes. On the MEA, neuronal cells were cultured directly on the surface of the chip. For initial experiments, static cultures were performed to investigate the biocompatibility of all included materials inside the prototype. BEOnChip performed a static cell culture with skin cells (Ha- CaT) in their device. Normal cell viability and morphology was observed after 96 h and 21 days of culture using Calcein-AM/PI live/ dead staining. MCS performed static cell culture using hiPSCs-derived neurons directly cultured on the PLO/laminin-coated MEA chips. After 14 days of culture, eGFP staining showed normal cell morphology and network formation. Bi/ond performed an endothelial cell culture (HMEC-1), showing proper cell adhesion and viability in their devices. The biological experiments under static conditions showed normal cell morphology and viability in all integrated devices. In the next phase of the project, the full SMWP platform with integrated perfusion will be used for biological experimentation to generate an air-liquid interface with skin cells (BEOnChip), a perfusable MEA (MCS) and endothelial tube formation under unidirectional flow (Bi/ond).
