The preset disclosure provides methods of culturing cells, e.g., pluripotent cells, multipotent cells, and/or immune cells (e.g., T cells and/or NK cells) in a medium comprising at least about 5 mM potassium ion, wherein the medium is not hypertonic. In some aspects, the medium is hypotonic. In some aspects, the methods disclosed herein increases the number of less-differentiated cells in the population of cells. In some aspects, the cultured cells are engineered, e.g., to comprise a chimeric antigen receptor or an engineered T cell receptor. In some aspects, the cells are administered to a subject in need thereof.

The present invention provides a medium composition containing deacylated gellan gum or a salt thereof, and an acidic polysaccharide or a salt thereof capable of maintaining a random coil state in a divalent metal cation medium and cross-linking via a divalent metal ion, and permitting culture of a cell or a tissue in suspension, wherein a concentration of the deacylated gellan gum or a salt thereof in the medium composition is 0.002-0.01 (w/v) %, a concentration of the acidic polysaccharide or a salt thereof is 0.004-0.1 (w/v) %, and a mass ratio of the acidic polysaccharide or a salt thereof to the deacylated gellan gum or a salt thereof is not less than 1. In addition, the present invention provides a method for isolating a cell or tissue from a culture preparation containing the medium composition and cell or tissue, including applying a shear force to the culture preparation.

The present invention provides a method for inducing differentiation of neural stem cells. The present invention provides optimized differentiation conditions of neural stem cells into neurons using a patterned hydrogel.

A process includes growing NRB in a nitrate reducing bacteria media to form a NRB culture and combining the NRB culture with a concentrated nitrate solution to form a NRB composition.

Described herein is a method of treating a disorder, the method comprising: administering to a subject in need thereof a composition that contains a population of somatic stem cells that are 0.3-6.0 micrometers in size and CD9+, CD349+, CD133?, CD90?, CD34?, SSEA1+, SSEA4+, CD13+, or Stro1+, wherein the disorder is selected from the group consisting of a neurodegenerative disease, nervous system disorder, cancer, metabolic disorder, autoimmune disorder, inflammatory disorder, heart or circulatory disorder, blood disorder, muscular dystrophy, gastrointestinal disease, kidney disease, liver disease, lung disease, adrenal disorder, a condition resulting from an injury, a condition associated with aging, and virus infection.

The present invention relates to an AG-haESCs in which H19 DMR and IG-DMR are knocked out, a method for preparing the AG-haESCs, and use of the AG-haESCs in constructing a genetically modified semi-cloned animal and a library of a genetically modified semi-cloned animal. The AG-haESCs is capable of obtaining characteristics resembling a round spermatid, and upon injection into an oocyte, a viable SC mouse is stably obtained. The present invention is capable of being effectively used in multi-gene genetic manipulation, advancing the acquisition of animals with multiple genetic modifications.

The present invention provides a mutated woodchuck post-transcriptional regulatory element (WPRE). In particular, the present invention relates to a mutated WPRE sequence that can efficiently express nucleotides of interest in a retroviral vector system. The present invention also relates to methods of delivering and expressing nucleotides of interest to a target cell.

The present invention relates to an a process for manufacturing dry powder cell culture media. The preparation and usage of mixed particles generated by co-lyophilisation leads to homogenously blended cell culture media.

Methods and compositions for modifying glycans (e.g., glycans expressed on the surface of live cells or cell particles) are provided herein.
