Abstract: Disclosed are methods of culturing cells. The methods may comprise providing the cells and a culture incubator comprising a cell culture container; and an inflow of gas, wherein the cells are contained in the cell culture container. The methods may further comprise providing a continuous inflow of a cell culture gas to the culture incubator, incubating the cells in the culture incubator, monitoring the pericellular oxygen concentration of the cells in the cell culture container, and adjusting the inflow of the cell culture gas, thereby adjusting the pericellular oxygen concentration to a target oxygen concentration. Disclosed are culture incubators, comprising a cell culture container; and an inflow of gas, wherein cells are contained in the cell culture container.

Abstract: Disclosed is a technology for assaying individual cells, in which the identity of each individual cell in an ordered array is determined from coordinates assigned to it, and can be readout at high throughput with microscope. The method is able to test responses of millions of identical cells in multiple chemical and physical processes with superior statistics power to facilitate deep data mining.

Abstract: Disclosed herein are functionalized dopamine derivatives comprising an optionally substituted acrylic acid moiety and optionally a polyethylene glycol linking moiety. The functionalized dopamine derivatives are useful in cryogel formulations to improve the adhesivity of the cryogel, while preventing undesirable oxidation typically associated with dopamine-containing hydrogels and cryogels. Properties such as cryogel adhesivity, pore size, and interconnectivity are tunable features. Also provided herein are methods of treating a wound or promoting tissue regeneration with a cryogel of the invention or a formulation comprising such a cryogel.

Abstract: The invention provides polymer compositions for cell and drug delivery.

Abstract: Disclosed are biocompatible cryogels comprising one or more biomolecules, such as antibodies, protein complexes, enzymes, dna and polysaccharides. Also disclosed are methods of making the cryogels.

Abstract: A hydrogel retinal tamponade agent is disclosed herein. The disclosed hydrogel tamponade agent acts as a temporary barrier to fluid flow into the subretinal space and obviates the need to use intraocular gases or silicone oil as a retinal tamponade agent in a retinal detachment repair procedure. The hydrogel tamponade agent remains in place after a permanent seal is achieved and is slowly resorbed. The hydrogel tamponade agent is preferably biocompatible.

Abstract: The present disclosure relates to a hypoxia-inducing cryogel, comprising one or more polymer and one or more hypoxia-inducing agent. The present disclosure additionally relates to a hypoxia-inducing construct, comprising a cryogel and a support. Methods of reducing concentration of oxygen in a medium, comprising contacting the medium with a hypoxia-inducing cryogel (HIC) or a hypoxia-inducing construct are disclosed. Additionally, methods of inducing hypoxia in a cell, comprising contacting the cell with a medium, wherein the medium comprises a HIC or a hypoxia-inducing construct are disclosed.

Abstract: Disclosed are compositions and methods for preventing an infection, such as COVID-19 infection, comprising administering to the subject an oxygen-generating cryogel, wherein the oxygen-generating cryogel comprises an antigen, a chemoattractant for immune cells, an adjuvant, such as toll-like receptor 9 (TLR9) ligand, and an oxygen-producing compound. Described herein are methods of modulating the immune system in a subject, comprising administering an effective amount of the vaccine described herein to the subject, thereby modulating the immune system in the subject.

Abstract: Disclosed are nanocomposite oxygen-generating cryogels and their uses in reducing hypoxia in a biological tissue, such as a tumor. Methods of treating cancer with the disclosed cryogels are also provided.
