Provided are a method for producing a cell tissue, including a culturing step of culturing cells capable of serving as a feeder inside opening pores and communicating pores of a porous film having a plurality of the opening pores provided on a surface thereof and the communicating pores communicating mutually adjacent opening pores with one another; and a porous film including a plurality of opening pores provided on a surface thereof and communicating pores communicating mutually adjacent opening pores with one another.

The present invention is directed to a method of generating multilineage potential cells by de-differentiation of somatic leukocytes in a mixed leukocyte suspension from a blood sample. The present invention is also directed to the use of the generated multilineage potential cells to treat conditions in humans and mammals.

Disclosed are compounds and compositions for slowing, preventing, or reversing platelet damage, particularly as may occur during blood banking or during refrigeration of platelets. Also disclosed herein are methods for storing platelets and methods for improving platelet survival upon transfusion with one or more compounds or compositions as described herein.

The present disclosure provides methods and compositions for generating populations of auxotrophic cells and populations of differentiated cells and selecting populations of transfected cells using split auxotrophy.

A production method for a genetically modified megakaryocyte, the method including a step of introducing a CRISPR-associated (Cas) family protein and guide RNA (gRNA) into a megakaryocyte to modify a subject gene, in which the Cas family protein and the gRNA to be introduced into the megakaryocyte in the step form a complex beforehand. This production method is useful as a technique for producing a genetically modified megakaryocyte and a modified platelet.

The present invention provides isolated immune cells, immune cell populations and compositions, as well as markers, marker signatures and molecular targets characterising the immune cells. The cell products, substances, compositions, markers, marker signatures, molecular targets, kits of parts and methods of the present invention provide for new ways to characterise, evaluate and modulate the immune system and immune responses.

Methods for using cyclin-dependent kinase (CDK) inhibitors to enhance growth and self-renewal of progenitor cells, in vitro and in vivo.

A system and method of isolating extracellular vesicles. The method includes loading one or more of blood or bone marrow into an input port of a concentration system and centrifuging one or more of the blood or bone marrow to separate one or more of red blood cells, platelet poor plasma, or platelet rich plasma/bone marrow concentrate fractions via a centrifuge device. The method further includes pumping one or more of bone marrow/platelet rich plasma fractions and platelet poor plasma fractions into a receptacle of the concentration system and adding a concentrated aqueous two-phase solution to one or more of the bone marrow concentrate/platelet rich plasma fractions and platelet poor plasma fractions. The method also includes drawing the concentrated aqueous two-phase solution and one or more of the bone marrow concentrate/platelet rich plasma fractions or platelet poor plasma fractions back into the centrifuge device to isolate one or more of extracellular vesicles and platelet rich plasma/bone marrow concentrate fractions.

The present invention relates to a platelet rich plasma (PRP) extracting device and extracting method using the same, and more particularly, to a platelet rich plasma (PRP) extracting device capable of quickly and effectively extracting the highly concentrated PRP from centrifuged blood by a simple manipulation.

The invention relates to ex vivo methods of modulating gamma variable 4 (Vγ4) T cells using antibodies or fragments thereof, which specifically bind to a Vγ4 chain of a γδ T cell receptor (TCR) and not to a gamma variable 2 (Vγ2) chain of a γδ TCR. Methods of treatment and other uses of expanded populations of Vγ4 T cells produced by said methods are also provided.
