Abstract: A 3D tissue culture selected from the group consisting of hydrogel-based 3D tissue culture and cellular self-assembly 3D tissue culture as well as self-assembly 3D tissue culture. Additionally, disclosed is a method of preparing cells for 3D tissue culture, which method comprises the steps of plating the cells on a suitable surface, optionally, checking for their capability to adhere to said surface, discarding the cells which have not adhered to said surface, detaching the adhered cells and transferring them into a 3D tissue culture process.

Abstract: Disclosed herein is a transport device comprising a first section of an outer container comprising a shell on the inside having the shape of a spherical cap with an inner diameter and an opening, wherein the opening of the spherical cap faces upwards, and an inner container having an upper section, a lower section and an inner hollow volume defined thereby, wherein at least the lower section has a spherical shape on the outside, the outer diameter of which is smaller than the inner diameter of the spherical cap of the outer container. The inner container is suitable to be arranged in the spherical cap of the outer container in a freely pivotable fashion, and is capable of accommodating a payload.

Abstract: Provided is a system and a method for propagating cells, the system comprising a multi well plate and a plate sealing means for sealing at least one well of a multiwell plate, the plate sealing means comprising at least one solid bulge or at least one bulge comprising a solid base, said at least one bulge consisting of a resilient elastomer to securely seal at least one well of the multiwell plate. Also disclosed is the use of such a system for propagating cells and the corresponding method.

Abstract: A hanging drop plate and a method of cultivating cells or of producing molecular aggregates in at least one liquid volume that adheres to a drop contact area of such a hanging drop plate. The hanging drop plate has a body with a first surface and a second surface that is essentially coplanar to the first surface. The second surface has a drop contact area for adherently receiving a liquid volume. The drop contact area is distinguished from a surrounding area by a relief structure that prevents spreading of the liquid volume on the second surface of the body. The body has at least one conduit that mouths into the drop contact area from the direction of the first surface of the body. A liquid volume is applied to the drop contact area through a communicating conduit. Cells and/or molecules can be introduced into this liquid volume.

Abstract: Multi-well plate (1) comprising a plurality of wells (4), a frame (5) for holding the plurality of wells (4) in a defined arrangement, a support element (50) for contacting a surface when the multi-well plate (1) is placed on the surface, wherein at least one well (4) of the plurality of wells is elastically displaceable relative to said support element (50).
