Polypeptides having target levels of C-terminal variants are described.

Some embodiments include a genetically engineered cell comprising a nucleic acid encoding a detectable polypeptide operably linked to the Msi1 or Msi2 promoter and genetically engineered organisms comprising these genetically engineered cells.

Provided is a method for producing chondrocytes from pluripotent stem cells, the method comprising the steps of: (i) culturing pluripotent stem cells under adherent conditions in a medium containing an HMG-CoA reductase inhibitor and one or more substances selected from the group consisting of BMP2, TGF and GDF5, and (ii) culturing the cells obtained in step (i) under suspension conditions in a medium containing an HMG-CoA reductase inhibitor and one or more substances selected from the group consisting of BMP2, TGF and GDF5. Also provided is a pharmaceutical product comprising chondrocytes obtained by the method.

The present disclosure relates to an isolated anti-FcRn antibody, which is an antibody binding to FcRn (stands for neonatal Fc receptor, also called FcRP, FcRB or Brambell receptor) that is a receptor with a high affinity for IgG or a fragment thereof, a method of preparing thereof, a composition for treating autoimmune disease, which comprises the antibody, and a method of treating and diagnosing autoimmune diseases using the antibody. The FcRn-specific antibody according to the present disclosure binds to FcRn non-competitively with IgG to reduce serum pathogenic auto-antibody levels, and thus can be used for the treatment of autoimmune diseases.

The present invention provides a method polyclonal stimulation of T cells, the method comprising contacting a population of T cells with a nanomatrix, the nanomatrix comprising a) a flexible matrix, wherein said matrix is of polymeric material; and b) attached to said polymeric flexible matrix one or more polyclonal stimulatory agents which provide activation signals to the T cells; thereby activating and inducing the T cells to proliferate; wherein the nanomatrix is 1 to 500 nm in size. At least one first and one second stimulatory agents are attached to the same or to separate flexible matrices. If the stimulatory agents are attached to separate beads, fine-tuning of nanomatrices for the stimulation of the T cells is possible.

Fibronectin type III domains (FN3) that specifically bind to CD8A, related polynucleotides capable of encoding CD8A-specific FN3 domains, cells expressing the FN3 domains, as well as associated vectors, and detectably labeled FN3 domains are useful in therapeutic and diagnostic applications.

The invention provides a method of differentiating human pluripotent stem cells to ectodermal cell by treating human pluripotent stem cells, which are dissociated single cells, and inducing differentiation to ectodermal cells under conditions where a ROCK(Rho-kinase) inhibitor is present in a culture medium in contact with the cells after dissociation of the human pluripotent stem cells.

Herein is reported a method for the production of an immunoglobulin comprising the following steps: a) providing a eukaryotic cell comprising a nucleic acid encoding the immunoglobulin, b) cultivating the eukaryotic cell in a cultivation medium wherein the amount of glucose available in the cultivation medium per time unit is kept constant and limited to less than 80% of the amount that could maximally be utilized by the cells in the cultivation medium per time unit, and c) recovering the immunoglobulin from the culture.

Methods and materials are described for human genome prophylaxis and therapy of diseases using myoblast transfer. These methods result in gene transcript changes in multiple pathways. Linking the myoblast transfer technology development from DMD, cardiomyopathy, and Type-II diabetes, the myoblast transfer demonstrably mediates its effect through transfer of the normal myoblast nuclei that supply the complete human genome, in addition to just replenishing the missing gene(s) or the aberrant gene(s). The replacement genes then transcribe to produce the necessary proteins or factors for genetic repair. A variety of uses of this technology are described, including that for disease treatment, disease prevention, drug discovery, and selection of superior cells and clones for therapy.

Disclosed are methods and compositions of microbead carriers for delivery of cells and other biologically active substances to diseased or damaged tissue in a subject in need thereof.
