Formation of Array of Membranes and Apparatus Therefor

An array of membranes comprising amphipathic molecules is formed using an apparatus comprising a support defining an array of compartments. Volumes comprising polar medium are provided within respective compartments and a layer comprising apolar medium is provided extending across the openings with the volumes. Polar medium is flowed across the support to displace apolar medium and form a layer in contact with the volumes, forming membranes comprising amphipathic molecules at the interfaces. In one construction of the apparatus, the support that comprises partitions which comprise inner portions and outer portions. The inner portions define inner recesses without gaps therebetween that are capable of constraining the volumes comprising polar medium contained in neighbouring inner recesses from contacting each other. The outer portions extend outwardly from the inner portions and have gaps allowing the flow of an apolar medium across the substrate.

METHODS FOR PATTERNING HYDROGELS INTO MULTI-WELL PLATES
20180348637 · 2018-12-06 ·

The inventive subject matter provides methods for reproducibly fabricating hydrogel-based organ and tumor models inside multi-well plates. A hydrogel precursor, which can include cells, is instilled into a well. A pillar is inserted into the well to contact the hydrogel precursor with a surface that can be shaped or textured to provide a desired surface configuration or contour, for example that of a desired organoid or tumor feature. The hydrogel precursor is polymerized and the pillar removed. A second hydrogel precursor, which can contain a different cell type, is then instilled into the well and a second pillar, which can have a different configuration or texture, inserted. Subsequent polymerization generates a second hydrogel portion within the well. Polymerization can be carried out by photopolymerization. Different wells can be aligned with different, individually controlled light sources or a single, collimated light source.

The inventive subject matter provides an apparatus for reproducibly fabricating hydrogel-based organ and tumor models inside multi-well plates. For example, tumor models made using the inventive apparatus can be used for studying the progression of cancer, cancer diagnostics, and therapeutic screening. A mold controls the thickness of each hydrogel layer. A photomask controls the size and shape of each hydrogel layer, allowing the hydrogel diameter to be smaller than the diameter of each well so that liquid media can be exchanged around both the sides and top of the hydrogels. A holder aligns the photomask with the multi-well plate, and polymerization is initiated by a light source.
