The present invention relates to a cell culture medium, in particular for culturing autologous fibroblasts, for use in aesthetic medicine for skin transplantation, said culture medium being serum-free and being characterized in that it contains glucose in a much lower quantity than conventional culture media.

This application relates to non-human primate (NHP) induced pluripotent stem cell (IPSC)-derived hepatocytes, for example, Cynomolgus monkey (Macaca fascicularis) induced pluripotent stem cell-derived hepatocytes, and methods of producing the same. Moreover, this application relates to methods of using NHP IPSC-derived hepatocytes for drug screening, drug safety assessment and in models of infection.

Provided is an isolated population of human pluripotent stem cells comprising at least 50% human pluripotent stem cells characterized by an OCT4+/TRA1-60−/TRA1-81−/SSEA1+/SSEA4− expression signature, and novel methods of generating and maintaining same in a pluripotent, undifferentiated state a suspension culture devoid of cell clumps. Also provided are novel culture media, cell cultures and methods for culturing pluripotent stem cells in a suspension culture or a two-dimensional culture system while maintaining the cells in a proliferative, pluripotent and undifferentiated state. The novel culture media comprise interleukin 11 (IL11) and Ciliary Neurotrophic Factor (CNTF); bFGF at a concentration of at least 50 ng/ml and an IL6RIL6 chimera; or an animal contaminant-free serum replacement and an IL6RIL6 chimera. Also provided are methods for generating lineage-specific cells from the pluripotent stem cells.

A chemically defined medium for differentiation of muscle stem cells in vitro, namely a serum-free, more efficient and inexpensive chemically defined medium for inducing differentiation of muscle stem cells in vitro. Compared with an existing general muscle stem cell differentiation medium, using the chemically defined medium can increase the relative expression of myogenin genes by 4.48 times on the 2.sup.nd day of differentiation, increase the relative expression of myosin heavy chain genes by 55.28 times on the 6.sup.th day, and increase the percentage of cell differentiation from 34.94% to 57.93% in the terminal differentiation stage, and more, thicker and longer muscle fibers are formed through induced differentiation. The chemically defined differentiation medium further improves the differentiation efficiency of muscle stem cells, and provides a more efficient and inexpensive method for differentiation of muscle stem cells into myotubes, and for 3D culture of muscle stem cells to produce cell cultured meat.

The present disclosure relates to a method for the cultivation of primary cells. The primary cells are cultivated in a serum free medium supplemented with peptides and peptones derived from plant or vegetable sources. The method for the cultivation of primary cells may be one step in a method for the amplification of viruses, such as poxviruses.

The present disclosure relates to the use of laminin-521 in obtaining retinal pigment epithelium (RPE) cells. Pluripotent human embryonic stem cells are cultured on plates coated with recombinant laminin-521 (laminin-11), in totally defined and xeno-free conditions. A first cell culture medium contains a growth factor, and a second cell culture medium does not contain growth factor. The stem cells are first exposed to the first cell culture medium, then exposed to the second cell culture medium for a longer time period. After a number of weeks, clinical grade RPE cells are obtained from the stem cells.

The present disclosure provides compositions for and methods of monitoring the progression of and treating gastrointestinal infections in a subject, particularly those involving Clostridioides difficile.

The present invention is in the field of pluripotent stem cells. In particular the invention relates to a method for (closed system) induction of differentiation of pluripotent stem cells towards a pre-selected cell type, such as, for example, cardiomyocytes or endothelial cells. The method as disclosed herein is particularly useful to upscale the production of cells derived from pluripotent stem cells, in particular (human) cardiomyocytes and/or endothelial cells derived from pluripotent stem cells.

Methods are disclosed for reprogramming a somatic cell, including an adherent cell and a cell in suspension, into an induced pluripotent stem comprising expressing exogenous Sox-2, exogenous Klf-4, exogenous Oct3/4 from DNA that has not integrated into the genome of the somatic cell, suppressing p53 activity within the somatic cell, and exposing the somatic cell to reprogramming-assistance factors comprising an exogenous Alk-5 inhibitor, an exogenous histone deacetylase inhibitor, and an exogenous activator of glycolysis. Compositions and kits for use in such methods are also disclosed as are cells made by such a method.

The present invention relates to a method for regulating potency of pluripotent stem cells (PSCs) by modulating expression of podocalyxin-like protein 1 (PODXL) and applications thereof.
