Use of cyclosporin A (CsA) or a derivative thereof for increasing the efficiency of transduction of an isolated population of human haematopoietic stem and/or progenitor cells by a vector derived from HIV-1, HIV-2, FIV, BIV, EIAV, CAEV or visna lentivirus.

A method for fabricating a bone-regeneration scaffold may include providing a printing material including a biologically-derived bone powder, and fabricating, via a 3D printer, the bone-regeneration scaffold using the printing material.

The disclosure provides a powder form and a hydrogel composition for alleviating degenerative joint and tendon tear. The powder form consists essentially of a 120-380 parts by weight biodegradable copolymer; 15-75 parts by weight urea; and 100 parts by weight platelet-rich plasma; wherein the biodegradable copolymer has a structure of formula (I) or formula (II):

##STR00001##

wherein A comprises a hydrophilic polyethylene glycol polymer; B comprises a hydrophobic polyester polymer; BOX is bifunctional group monomer of 2, 2-bis(2-oxazoline) used for coupling the blocks AB or BAB; and n is an integer greater than or equal to 0.

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.

One aspect relates to a composition for use in a therapeutic procedure, which comprises calcium sulfate, an alkaline earth carbonate, a binder, and up to 2.5 percent by weight gentamicin sulfate, based on the total mass of the composition, and to a production method for such a composition. The composition can be used as a bone substitute material.

The invention relates to hardenable ceramic bone substitute compositions having improved setting, powders for such compositions and methods for their manufacture and use in medical treatment. More specifically the invention relates to hardenable bone substitute powder and hardenable bone substitute paste with improved setting properties, comprising calcium sulfate and heat-treated hydroxyapatite (passivated HA), which bone substitute is suitable for treatment of disorders of supportive tissue such as bone loss, bone fracture, bone trauma and osteomyelitis.

The present invention relates to an implantable device configured to deliver, to an injured bone site, components for revascularisation and bone repair, the device comprising: a first osteoconductive scaffold component adapted to hold and deliver to the injured bone site, growth factors for inducing cellular events that initiate healing; and comprising a second osteoconductive scaffold component adapted to hold and deliver to the injured bone site, viable autologous osteogenic and/or angiogenic cells, and wherein the device also comprises a third scaffold component adapted to promote bone cell proliferation and vascularity, whereby the scaffold components provide a stable mechanical environment for promoting bone cell proliferation and vascularity. The present invention also relates to a method of manufacture of the implantable device.

A bone cement paste containing a powder component comprising -tricalcium phosphate (-TCP) particles having an average size greater than or equal to 9 m, and a liquid component comprising blood is disclosed. A method for preparation of the phosphocalcic cement composition is also disclosed.

The present invention provides methods and compositions useful in the regeneration of damaged, lost and/or degenerated tissue in humans and animals. In certain embodiments, the present invention provides an acellular bioabsorbable tissue regeneration matrix, methods of making such a matrix, and methods of using such a matrix for the regeneration of damaged, lost and/or degenerated tissue. In certain embodiments, methods and compositions of the present invention are useful in the treatment of damaged, lost and/or degenerated nerve tissue.

Techniques, mixtures, mixing and delivery kits, and improved delivery instruments for implantation of micronized allograft tissue over a microfractured defect. Allograft cartilage tissue is delivered over a cartilage defect that has been debrided and microfractured, without the need for a periosteal covering or separate type of patch sewn over the top. The allograft tissue may be any micronized cartilage particulates obtained by various methods, for example, cartilage delivered in its native form, dehydrated via lyophilization, freeze-dried, dehydrated via desiccation, or dehydrated by any other method.
