A mesenchymal stem cell culture product and a method for preparing the same are provided. The method for preparing the mesenchymal stem cell culture product includes the following steps. A predetermined quantity of mesenchymal stem cells is seeded in a flat culture device containing a first cell culture medium. When the mesenchymal stem cells proliferate to a target quantity, the first cell culture medium is replaced with a second cell culture medium, and the second cell culture medium is removed after incubation for 18 to 30 hours. A target cell culture medium is added and incubated for 48 to 72 hours. The target cell culture medium is collected repeatedly. The collected target cell culture medium is filtered and concentrated to obtain the mesenchymal stem cell culture product.

The invention provides culture platforms, cell media, and methods of differentiating pluriptent cells into hematopoietic cells. The invention further provides pluripotent stem cell-derived hematopoietic cells generated using the culture platforms and ethods disclosed herein, which enable feed-free, monolayer culturing and in the absence of EB formation. Specifically, pluripotent stem cell-derived hematopoietic cell of this invention include, and not limited to, iHSC, definitive hemogenic endothelium, hematopoietic multipotent progenitors, T cell progenitors, NK cell progenitors, T cells, and NK cells.

Disclosures herein are directed to chemically defined animal-derived component free supplements designed for individual cell types that supports the ex vivo growth of cells as well or better than serum, in chemically defined conditions.

The disclosure relates to stem cells and their therapeutic use in the treatment and/or prevention of pancreatic diseases or disorders. Provided herein are compositions comprising c-kit positive pancreatic stem cells and methods of preparing and using c-kit positive pancreatic stem cells for the treatment and/or prevention of pancreatic diseases or disorders.

Provided is a culture medium containing amphiregulin for culturing primary breast epithelial cells and a culture method involving using the medium. In the culturing method, primary cells are cultured on a culture vessel coated with an extracellular matrix gel by using the culture medium, and the primary cells grow on the culture vessel, which has been coated with the extracellular matrix gel, and proliferate rapidly under the combined action of nutrient factors and an extracellular matrix contained in the primary cell culture medium. The cell model obtained by the primary cell culture medium and the primary cell culture method can be used for the evaluating the efficacy of and screening drugs.

The present invention aims to solve a problem in T-cell transfer therapy and the like, which is T-cell exhaustion, and to provide a technique to enhance T cell activity. T cells having cell surface markers of CD45RA.sup.+ and CCR7.sup.+ can be produced by culturing activated T cells in the presence of (a) a conditioned medium derived from stromal cells or (b) CXCL12.

The present invention provides methods to promote the differentiation of pluripotent stem cells and the products related to or resulting from such methods. In particular, the present invention provides an improved method for the formation of pancreatic hormone expressing cells and pancreatic hormone secreting cells. In addition, the present invention also provides methods to promote the differentiation of pluripotent stem cells without the use of a feeder cell layer and the products related to or resulting from such methods. The present invention also provides methods to promote glucose-stimulated insulin secretion in insulin-producing cells derived from pluripotent stem cells.

Embodiments of the disclosure concern methods and compositions related to cancer treatment for an individual utilizing recombinant fibroblast cells that comprise one or more activities that are endothelial cell-like. The cells are delivered to a tumor microenvironment following which their death results in destabilization of the tumor vasculature. In particular embodiments, the fibroblast cells recombinantly express one or more of ETV2, FOXC2, and FLI1.

The present invention provides a new method for producing Engineered Heart Muscle (EHM) under chemically fully defined conditions all compatible with GMP regulations. The resulting human myocardium generates force and shows typical heart muscle properties.

Embodiments herein relate to in vitro production methods of hematopoietic stem cell (HSC) and hematopoietic stem and progenitor cell (HSPC) that have long-term multilineage hematopoiesis potentials upon in vivo engraftment. The HSC and HSPCs are derived from pluripotent stem cells-derived hemogenic endothelia cells (HE) by non-integrative episomal vectors-based gene transfer.
