This invention provides a system for efficiently producing differentiated cells from pluripotent cells, such as human embryonic stem cells. Rather than permitting the cells to form embryoid bodies according to established techniques, differentiation is effected directly in monolayer culture on a suitable solid surface. The cells are either plated directly onto a differentiation-promoting surface, or grown initially on the solid surface in the absence of feeder cells and then exchanged into a medium that assists in the differentiation process. The solid surface and the culture medium can be chosen to direct differentiation down a particular pathway, generating a cell population that is remarkably uniform. The methodology is well adapted to bulk production of committed precursor and terminally differentiated cells for use in drug screening or regenerative medicine.

Cells derived from postpartum placenta and methods for their isolation are provided by the invention. The invention further provides cultures and compositions of the placenta-derived cells. The placenta-derived cells of the invention have a plethora of uses, including but not limited to research, diagnostic, and therapeutic applications.

The present invention is concerned with a composition and in vitro method for generating a desired cell type and/or tissue type from hair follicular stem cells. The composition and in vitro method are particularly suitable for generating an autologous desired cell type and/or tissue type. Furthermore, the composition and method are especially efficient and suitable for use in the context of cosmetic cell and/or tissue transplantation in recipient areas of a subject experiencing cell and/or tissue loss caused by, for example, a wound, scar, burn injury, tissue degeneration, and aging. The composition and in vitro method are also suitable to circumvent complications related to infections and/or immune rejection of a cosmetic cell and/or tissue implant or graft.

The present disclosure relates generally to an improved gene expression system in the field of recombinant gene expression. The invention relates to a system showing an improved yield and quality of protein production and methods for increasing production of a protein produced by cultured cells, particularly cultured eukaryotic cells.

A cell culture media comprising an effective amount of 3-Thiopheneacetic acid (3TAA).

The present invention provides methods and kits for differentiating podocytes from pluripotent stem cells and from other cell types.

This patent application relates to a method for determining the in vitro efficacy profile of a drug candidate using standardized cell cultures of uniformly distributed differentiated neural cells (NCs) from at least two primate species, wherein the differentiated NC cultures are qualified for high throughput screening based on a dissociation and reseeding step performed on the differentiated NCs. The method includes differentiating human and/or non-human primate neuronal precursor cells (NPCs) to neuronal cells (NCs) followed by dissociating the differentiated NCs from its support and reseeding the differentiated NCs in a high-throughput cell culture format resulting in robust cultures suitable for high-throughput drug screening assays, in particular to screen antisense oligonucleotides.

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.

This patent application relates to a method to generate standardized and robust neuronal cell culture assays from primate species, for example suitable for high-throughput screening of drug candidates. The method includes differentiating human and/or non-human primate neuronal precursor cells (NPCs) to neuronal cells (NCs) and producing uniform NC cultures based on a dissociation and reseeding step performed on the differentiated NCs resulting in robust cultures suitable for high-throughput drug screening assays, in particular to screen antisense oligonucleotides.

The present invention relates to the production and culture of undifferentiated spermatogonial stem cells that can be maintained long term and are feeder free. The resultant feeder-free populations can be used in any of a number of protocols including the generation of progeny bulls. The present invention includes novel methods required for the successful enrichment of bovine spermatogonial stem cells, novel cell lines and other components used for the same, as well as the resultant stem cell compositions.
