The present invention provides a basal cell culture medium and a feed medium with novel amino acid ratios and/or iron choline citrate as iron carrier that result in improved performance of mammalian cell culture processes, such as CHO cultivation and protein production processes, in particular in increased product titer (e.g. of monoclonal antibodies). Also provided are methods for culturing mammalian cells and producing a protein of interest using said basal cell culture medium and optionally feed medium. The invention also provides for a medium platform that comprises (i) the basal cell culture medium and (ii) the feed medium.

The present invention relates to animal protein-free cell culture media comprising polyamines and a plant- and/or yeast-derived hydrolysate. The invention also relates to animal protein-free culturing processes, wherein cells can be cultivated, propagated and passaged without adding supplementary animal proteins in the culture medium. These processes are useful in cultivating cells, such as recombinant cells or cells infected with a virus, and for producing biological products by cell culture processes.

Cell culture media comprising antioxidants are provided herein as are methods of using the media for cell culturing and polypeptide production from cells. Compositions comprising polypeptides, such as therapeutic polypeptides, produced by the methods herein are also provided.

Compositions and methods for culturing cells with theobromine are provided, as well as cells derived thereby. Theobromine compositions for enhancing bone formation, increasing bone density, increasing interconnections of internal bone, increasing bone mass, treating cartilage and/or bone defects, increasing fetal birth weight, preventing tooth decay, remineralizing a tooth surface, treating dentine hypersensitivity, and application to a bone site to promote new bone growth at the site are also provided.

A SMAC mimetic and pharmaceutical compositions thereof and methods of use.

Disclosure of a mammalian cytoplasmic donor cell line. Disclosure of a patient specific cell line. Methods to obtain a mammalian cytoplasmic donor cell line by fusing a differentiated mammalian cell and a functionally enucleated mammalian embryonic cell line. Methods to obtain a mammalian cytoplasmic donor cell line by fusing a differentiated mammalian cell and a functionally enucleated human cancer cell. Methods to obtain a patient specific cell line of a cell type similar to a mammalian cytoplasmic donor cell line by functionally enucleating the mammalian cytoplasmic donor cell line and fusing the functionally enucleated mammalian cytoplasmic donor cell line with a differentiated cell obtained from the patient. A method of treatment of a human patient by administering the patient-specific cell line to the patient.

The present invention relates to a method for culturing epidermis-derived stem cells comprising the step of culturing epidermis-derived stem cells in the presence of a three-dimensional extracellular matrix (3D-ECM) and a basal cell culture medium comprising: Epidermal Growth Factor (EGF); and/or a Vascular Endothelial Growth Factor (VEGF); and/or a Fibroblast Growth Factor (FGF); and further a ROCK (Rho-kinase) inhibitor. The present invention further relates to a method for ex vivo de novo generation of epidermis-derived stem cells. Furthermore, the present invention relates to an epidermis-derived stem cell that is obtainable by a method according to the present invention. Uses of said epidermis-derived stem cell, e.g. uses of said epidermis-derived stem cell for in vitro tissue production, in vitro drug discovery screening and medical applications, are also provided herein. The present invention further relates to a cell culture medium that is employed in the context of a method of the present invention.

The present invention provides a cell culture medium for culturing primary gastrointestinal stromal tumor cells, comprising gastrin, N2, insulin, a receptor tyrosine kinase ligand, and a Rock kinase inhibitor. The present invention further provides a method for culturing gastrointestinal stromal tumor cells by using the cell culture medium, and an application and a method of an expanded cell population, which is obtained by using the method, in efficacy evaluation or screening.

Provided are a storage method and a banking system of cells prepared using somatic cell nuclear transfer (NT) technology with homozygous genotypes of genes of human leukocyte antigen (HLA)-A, HLA-B, HLA-DR, and the like. The banking of NT cell-derived stem cells may be applied to autologous or allogenic patients and can provide transplantable cells and tissue materials for the treatment of various diseases such as diabetes, osteoarthritis, Parkinson's disease, and the like.

A process is provided for treating demineralized bone (DB) comprising incubating the DB with a solution of a chaotropic agent at a temperature in the range of about 12? C. to about 30? C. to increase the release of a bone growth factor followed by selectively removing the chaotropic agent while retaining the released growth factor and the DB. A product prepared by the process is also provided as is the use of said product to promote bone formation or bone fusion in a subject in need thereof.
