Publication number: 20190167723Abstract: A method of preparing an isolated serum fraction of platelet rich fibrin, cell cultures comprising said serum fraction and its use as a cell culture additive. The invention also relates to increasing proliferation rate of chondrocytes, to the treatment of articular or joint diseases and to increasing the proliferation rate of mesenchymal stem cells. The isolated serum fraction of platelet rich fibrin (PRF), is prepared by providing platelet rich plasma (PRP) without the addition of an anticoagulant; clotting the PRP to obtain a coagel of PRF; and separating the coagel to isolate the serum fraction which comprises an activated platelet releasate; and further provides for the isolated serum fraction obtained by such method, and its medical use.Type: ApplicationFiled: October 29, 2018Publication date: June 6, 2019Inventors: Zsombor LACZA, Gabriella VÁCZ, István HORNYÁK, Melinda SIMON, Olga KUTÉN, Vivek JEYAKUMAR

Publication number: 20180353118Abstract: A blood handling device (1) has a syringe (1(a)) for taking a blood sample, and a container (1(b)) releasably connected to the syringe. The syringe may be used to take a blood sample when the container (1(b)) is disconnected. The container is then re-connected and the full device is centrifuged so that a fraction migrates into a chamber (6) of the container (1(b)). This migration is through a fluid passageway (61, 82) between the syringe volume and the chamber (6). A connector (21) interfaces between the syringe (4, 20) and the container (5), the connector having the fluid passageway (61, 82). The connector has a first part (21(a)) forming a base for the syringe, and a second part (21(b)) arranged to connect to the container (1(b)) during centrifuging and to a cannula after removal of the container.Type: ApplicationFiled: November 17, 2016Publication date: December 13, 2018Inventors: Zsombor Lacza, István Hornyák
