The invention relates to peripheral blood mononuclear cell (PBMC) monolayers or bone-marrow cell monolayers and methods for its culture and corresponding uses of said monolayers. The present invention also relates, in some aspects, to screening methods comprising the PBMC monolayer or bone-marrow cell monolayer of the invention for determination of response or lack of response of a disease to a therapeutic agent and/or drug screening methods. In some aspects, the invention further relates to methods for diagnosing a disease or predisposition to a disease in a PBMC donor or bone-marrow cell donor comprising the PBMCs/bone-marrow cells cultured according to the method of the invention and/or to methods for determining whether the disease is likely to respond or is responsive to treatment with a therapeutic agent.

The data presented herein relates to therapeutic compositions of mesenchymal stem cells (MSCs). In particular, pharmaceutically acceptable MSC compostions are xenogen-free and do not have immunological adverse effects. Mesenchymal stem cells expanded in a cell culture media comprising bone marrow supernatant produce xenogen-free mesenchymal stem cells. Such xenogen-free MSC compositions improve therapy for medical conditions including, but not limited to, osteoarthritis, cardiovascular disorders and/or diabetes.

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.

Provided is a pre-conditioned mesenchymal stem cell (MSC), an exosome derived therefrom, and a cell-protective composition including the pre-conditioned MSC or the exosome. Also provided is a method for preparing the pre-conditioned MSC by contacting an MSC with an effective amount of ginkgolide A. Still provided is a method for promoting recovery or reducing death of damaged nerve cells, including administering to the damaged nerve cells a composition including the pre-conditioned MSC or the exosome.

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 invention is directed to osteochondroreticular stem cells and methods of using osteochondroreticular stem cells. In another aspect the invention is directed to a method of treating osteoarthritis or skeletal fractures using osteochondroreticular stem cells.
