The present invention provides novel methods for producing a viral vector. Corresponding viral vector production systems and uses are also provided.

The present invention provides a novel method for manufacturing a protein, particularly where said protein is to be coupled with another molecule. The invention further provides a method for industrial scale protein manufacturing to obtain proteins, e.g., for therapeutic purposes.

The present invention provides exosomes that are secreted from mesenchymal stem cells (MSCs) and compositions thereof. The invention also provides techniques to isolate, characterize and optimize manufacturing of such compositions to obtain highly purified and specialized exosomal populations. The compositions comprising populations of such exosomes are used as therapeutic approaches to treat cellular damages and associated conditions, particularly wound healing.

The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.

The present invention relates to methods of upregulating the high mannose glycoform content of a recombinant protein during a mammalian cell culture by manipulating the mannose to total hexose ratio in the cell culture media formulation.

The present disclosure relates to a simple, fast, and low cost method for 3D microvascular imaging, termed “scatter labeled imaging of microvasculature in excised tissue” (SLIME). The method can include perfusing a contrast agent through vasculature of a tissue sample. The contrast agent can include colloids and a dispersant. After the contrast agent is perfused through the vasculature, the vasculature of the tissue sample can be treated with a molecule that cross links with at least a portion of the dispersant to form a sticky, non-Newtonian polymer that prevents leakage of the contrast agent out of the vasculature of the tissue sample. The tissue sample can then be immersed in a solution comprising a clearing agent and subsequently imaged.

The present invention has as its object to find out new conditions that make it possible to induce cell death of non-cardiomyocytes or undifferentiated stem cells more completely and to select cardiomyocytes only.

In order to achieve this object, there are provided in the present application: a cell culture medium for use in inducing cell death of undifferentiated stem cells, wherein the cell culture medium is free of glutamine in the amino acid profile; and also a method for inducing cell death of non-cardiomyocytes by performing cell culture in said cell culture medium. Further provided in this application are: a cell culture medium for use in selecting cardiomyocytes, wherein the cell culture medium is supplemented with lactate, pyruvate or a fatty acid, free of sugar, and free of glutamine in the amino acid profile; and also a method for selecting cardiomyocytes by culturing a mixture of cardiomyocytes and non-cardiomyocytes in said cell culture medium.

A method for producing cell aggregates includes culturing cells while suspending the cells in a liquid culture medium comprising a lysophospholipid. A composition includes a lysophospholipid, wherein the composition is a liquid culture medium or a composition added to a liquid culture medium.

The present invention provides a second use of mitochondria, which can cure a tendon injury-related disease and prevent a disease caused by a tendon injury. Specifically, the mitochondria disclosed in the present invention have the effect of repairing injured tendon cells and accelerating the healing of the tendon cells. Therefore, by administering a predetermined amount of mitochondria or a composition containing a predetermined amount of mitochondria to a part with a tendon injury, wound healing of the part with the tendon injury can be promoted, thus achieving the effect of repairing the injured tendon and further preventing a joint disease caused by the tendon injury or inflammation.

The invention provides methods and materials for culturing mammalian cells and harvesting recombinant protein.
