METHODS AND ARTICLES FOR DELIVERING VIABLE CELLS INTO SOLID TISSUE
Embodiments provide swallowable devices, preparations and methods for delivering viable cells (VC) into the GI tract including GI wall tissue or other tissue site. Particular embodiments provide a swallowable device such as a capsule for delivering VC into an intestinal wall or other site. The VC can be contained within a tissue-penetrating shell disposed in the capsule that protects the VC as they pass through the GI tract until they are inserted into GI tract tissue or other location. The shell desirably has shape, size and material consistency to be contained in a swallowable capsule, delivered from the capsule into solid tissue by the application of force on the shell and biodegrade within the solid tissue to release the VC into the tissue. Within the shell or other structure the VC can be maintained in a viability-sustaining gel that preserves the viability of the VC for selected time periods.

KIDNEY REGENERATION ACCELERATOR AND PRODUCTION METHOD FOR SAME
The kidney regeneration accelerator that contains a component obtained by decellularizing a mammalian organ. The production method for a kidney regeneration accelerator that involves decellularizing a mammalian organ to obtain a component that includes an extracellular matrix, freeze drying and then pulverizing the component to obtain a powder, and performing a sterilization treatment on the powder. A pharmaceutical composition for use in treating kidney disease that contains a component obtained by decellularizing a mammalian organ. A treatment method for kidney disease that involves applying a pharmaceutical composition that contains a component obtained by decellularizing a mammalian organ to a site to be treated of the kidney of a human or animal kidney disease patient.
PROBIOTIC AND PREBIOTIC COMPOSITIONS, AND METHODS OF USE THEREOF FOR MODULATION OF THE MICROBIOME
Probiotic compositions containing non-pathogenic microbial entities, e.g., bacterial entities, are described herein. The probiotic compositions may optionally contain or be used in conjunction with one or more prebiotics. Uses of the probiotic compositions to treat or prevent disorders of the local or systemic microbiome in a subject are also provided.

SAFETY SWITCHES FOR REGULATION OF GENE EXPRESSION
Disclosed herein are cells including pluripotent stem cells that conditionally express an immunosuppressive factor and related methods of their use and generation. In some embodiments, the cells disclosed do not express MHC I and MHC II human leukocyte antigens, and in some cases, also do not express one or more TCR complexes. In some embodiments, hypoimmunogenicity of the cells is controlled by activation of a controllable expression system upon contacting the cells with a specific factor or agent.

System and method for microneedle delivery of microencapsulated vaccine and bioactive proteins
A method for producing at least one microneedle containing a vaccine for transdermal delivery of the vaccine to a patient includes preparing microparticles or nanoparticles of encapsulated vaccine by preparing a solution comprising a vaccine antigen and a biocompatible polymer matrix; and spray drying the solution to form the microparticles or nanoparticles. The method includes the further steps of preparing a film composition including at least one pre-polymer solution; preparing a suspension comprising the microparticles or nanoparticles and the film composition; loading the suspension into a 3D printer; printing, via the 3D printer, at least one microneedle made from the suspension; and, converting the pre-polymer solution into a cross-linked biopolymer by exposing the at least one microneedle to UV light. Also disclosed are microneedles containing a vaccine for transdermal delivery.

Cryopreserved in vitro cell culture of human pancreatic progenitor cells
The present invention relates to a cryopreserved in vitro cell culture comprising human pancreatic progenitor cells that co-express pancreatic-duodenal homeobox factor-1 (PDX1) and NK6 homeobox 1 (NKX6.1) and are chromogranin negative. The present invention also relates to a method for cryopreserving an in vitro population of human pancreatic progenitor cells that co-express PDX1 and NKX6.1 and are chromogranin negative.
