A composition includes porous silica particles to carry a cell fate modulating factor therein. A method for modulating cell fate includes treating various cells with the composition. The cell fate modulating factor is delivered to a stable target receptor, toxicity to subject cells for delivery may be reduced, a fate of the subject cells can be controlled through sustained release of at least 99 wt. % of the cell fate modulating factor.

The invention relates to a process for producing a plurality of capsules, each comprising an external shell of crosslinked hydrogel surrounding a central core, according to which a hydrogel solution and a composition of interest, intended to form the central core, are concentrically co-extruded so as to form mixed drops, each comprising a layer of hydrogel solution surrounding a drop of liquid composition of interest, characterized in that the co-extrusion step is carried out above a crosslinking aerosol so that the mixed drops pass through said crosslinking aerosol, such that the layer of hydrogel solution at least partially crosslinks around the drop of liquid composition of interest on contact with said aerosol.

A system for selective microcapsule extraction includes a non-planar core-shell microfluidic device. The non-planar core-shell microfluidic device generates microcapsules defining a core-shell configuration. A subset of the microcapsules contain aggregates, tissues, or at least one cell. A camera captures images of the microcapsules. A detection module includes a processor and a memory. The memory includes instructions that when executed by the processor causes the detection module to provide the images of the microcapsules as an input to a machine learning model. The machine learning model identifies microcapsules containing aggregates, tissues, or at least one cell. A force generator generates a force to extract the microcapsules. A microcontroller selectively activates the force generator to generate the force when the detection module identifies a microcapsule containing aggregates, tissues, or at least one cell to extract the microcapsule.

A method of treating or preventing overgrowth by pathogenic bacteria in a subject deficient in butyrate and/or butyrate-producing bacteria in their gut microbiota by administering a therapeutically effective amount of a butyrate-producing bacteria to the subject is described. A prebiotic can be included with the butyrate-producing bacteria. Overgrowth by pathogenic bacteria is commonly caused by antibiotic administration.

The present invention provides an improved method for producing pancreatic islet-containing capsules.

A method for producing pancreatic islet-containing capsules, comprising the steps of:

(a) preparing a sodium alginate solution A containing pancreatic islets at a concentration of 10,000 IEQ/mL or more;

(b) adding the sodium alginate solution to a divalent cation solution dropwise, and collecting gelled particles;

(c) adding the particles collected in step (b) to a poly-L-ornithine solution A, followed by stirring and then collecting particles;

(d) adding the particles collected in step (c) to a sodium alginate solution B, followed by stirring and then collecting particles; and

(e) adding the particles collected in step (d) to a sodium citrate solution, followed by stirring and then collecting particles.

A microcapsule which is used in tissue regeneration, which may be specifically directed to the damaged tissues, and which forms an extracellular matrix-like structure at a certain point and thus allows cell proliferation.

Provided herein are hydrogel cell matrices, hydrogel cell matrix systems for the support, growth, and differentiation of a stem cell or progenitor cell and methods for making such hydrogel cell matrices.

In one aspects of the invention, a microcapsule includes a film encapsulating a material. The film is formed by complexation of at least two mutually attractive components initially present in an aqueous dispersion comprising a continuous phase and a dispersed phase. The at least one first component is initially present in the continuous phase and the at least one second component is initially present in the dispersed phase. According to another aspect of the invention, provided is a process for forming microcapsules including the step of injecting a dispersed phase having at least a first component into a continuous phase having at least a second component, where the first component and the second component are mutually attractive, such that a film is formed by complexation of the first charged component and the second charged component.

A facility for industrial drying and/or encapsulation of thermolabile substances comprising at least one injection unit (1) wherein the thermolabile substance is introduced, an encapsulating material when the facility is used to encapsulate, a solvent, additives and an injection gas flow for obtaining droplets from the thermolabile substance. It further comprises a drying unit (2) through which the droplets and a drying gas are introduced for evaporating the solvent and comprises a collection unit (3) configured to separate the microcapsules generated from the drying gas and which is selected from a cartridge filter collector, a cyclone collector or a combination of the two. It also describes a method for the industrial encapsulation of thermolabile substances which is carried out at the proposed facility.
