MICROCARRIERS WITH SCAFFOLD STRUCTURE AND CONTINUOUS OUTER WALL FOR CULTURING CELLS
20230013733 · 2023-01-19 ·

The invention relates to a microcarrier, comprising a continuous medium of a biocompatible polymer for culturing cells and having a three-dimensional scaffold architecture delineated peripherally by a continuous outer wall, in which spherical macropores are stacked to one another and interconnected by connecting pores. The continuous outer wall is formed with exposure pores at positions where it is in contact with the macropores, through which the interior of the microcarrier may be in fluid communication with the ambient culture medium. The microcarrier herein is produced by cast-molding and, therefore, has a continuous outer wall which provides additional mechanical strength while maintaining high porosity. The microcarrier thus produced is configured in the form of a basic geometrical body. The invention further relates to a cast-molding process for producing the microcarrier.

Antigen-presenting cell-mimetic scaffolds and methods for making and using the same

Embodiments herein described provide antigen-presenting cell-mimetic scaffolds (APC-MS) and use of such scaffolds to manipulating T-cells. More specifically, the scaffolds are useful for promoting growth, division, differentiation, expansion, proliferation, activity, viability, exhaustion, anergy, quiescence, apoptosis, or death of T-cells in various settings, e.g., in vitro, ex vivo, or in vivo. Embodiments described herein further relate to pharmaceutical compositions, kits, and packages containing such scaffolds. Additional embodiments relate to methods for making the scaffolds, compositions, and kits/packages. Also described herein are methods for using the scaffolds, compositions, and/or kits in the diagnosis or therapy of diseases such as cancers, immunodeficiency disorders, and/or autoimmune disorders.

20220411737 · 2022-12-29 ·

An aseptic bioprocess package is provided herein. The aseptic bioprocess package includes a 2D flexible container including an interior compartment, a height having an upper half and a lower half, an inlet and an outlet, the inlet and the outlet being disposed on the same half of the 2D flexible container and a channel-forming feature in the interior compartment of the container, the channel-forming feature being configured to maintain a fluid flow path that fluidly connects the interior compartment of the flexible container with the outlet.

Polymeric Carriers and Methods

Provided are methods of controlling disassociation of cells from a carrier, compositions, and methods of collecting cells. The methods of controlling disassociation of cells from a carrier may include contacting a polymeric carrier with one or more digesting agents to disassociate at least a portion of a plurality of cells from the polymeric carrier. The polymeric carrier may be crosslinked with a crosslinker including at least one of a redox sensitive moiety, a UV light sensitive moiety, a pH sensitive moiety, and a temperature sensitive moiety.

Nanostraw well insert devices for improved cell transfection and viability

Described herein are nanostraw well insert apparatuses (e.g., devices and systems) that include nanotubes extending through and out of a membrane so that a material can pass through the membrane from a fluid reservoir depot and into a cell grown onto the nanotubes when electrical energy (e.g., electroporation energy) is applied. In particular, the device, systems and methods described herein may be adapted for cell growth viability and transfection efficiency (e.g., >70%). These apparatuses may be readily integratable into cell culturing processes for improved transfection efficiency, intracellular transport, and cell viability.

MATRICES FOR CELL CULTURE
20220396764 · 2022-12-15 ·

There is provided a cell culture matrix comprising a fungal derived protein. Also provided is a composition comprising the cell culture matrix as described herein, a cell culture system comprising the cell culture matrix as described herein, and a method of forming a cell culture matrix thereof.

Artificial antigen presenting cells for genetic engineering of immune cells

Disclosed herein are methods of producing chimeric antigen receptor (CAR) T cells using substrates, such as artificial antigen presenting cells, containing on a surface a a heparin binding domain (HBD), anti-CD3 single chain antibodies, anti-CD28 single chain antibodies (scFv), and optionally anti-41BBL antibodies. Anti-CD3 and Anti-CD28 scFvs bind and activate expanding T cells ex vivo, while the Heparin Binding Domain binds the viral vector, thereby bringing the T cells into close proximity with virus for effective gene transfer. This is a less costly, renewable, modifiable, and efficacious alternative to coated beads and RetroNectin® for gene transfer.
