Provided are fibrin or silk matrices comprising an oxygen carrier, and matrices, which comprise an oxygen carrier and mesenchymal stem cells. Also provided are methods of generating and using same for ex vivo or in vivo tissue regeneration and/or repair such as for treating a non-union bone fracture and a condition requiring spinal fusion.

Scaffolds with oxygen carriers, and their use in tissue regeneration

A composite scaffold for engineering a heterogeneous tissue is provided. The composite scaffold includes: (a) a first scaffold being capable of supporting formation of a first tissue type thereupon; and (b) a second scaffold being capable of supporting formation of a second tissue type thereupon; wherein the first scaffold and the second scaffold are arranged with respect to each other such that when the first scaffold supports the first tissue type and the second scaffold supports the second tissue type, a distance between any cell of the second tissue type and the first tissue type does not exceed 200 &#x3bc;m.

Composite scaffolds and methods using same for generating complex tissue grafts

The invention relates to methods of isolating and implanting mesenchymal stem cells for tissue repair or formation, without prior culture expansion of the mesenchymal stem cells. In particular, the invention relates to methods of isolating mesenchymal stem cells from bone marrow, for repairing or inducing formation of bone, without prior culture expansion of the mesenchymal stem cells. The invention further relates to an isolated, non-culturally expanded human adult mesenchymal stem cell population.

Methods of implanting mesenchymal stem cells for tissue repair and formation

A system for qualifying cells of a cell sample labeled with a magnetic or magnetizable moiety is provided. The system includes a cell sample holder for holding a cell of the cells and a first cell analyzer which includes a magnetic field source for applying a magnetic field to the cell and a sensor for qualifying and/or quantifying an effect of the magnetic field on the cell.

Systems and methods for analyzing and manipulating biological samples

This invention provides method for repairing, regenerating, treating, or inducing the repair of an injury, a defect or a condition of a connective tissue of a subject. This invention provides a method of regenerating, enhancing, inducing repair and/or development of connective tissue as a result of a defect, injury or condition of the connective tissue of a subject comprising the step of inserting an engineered cell which comprises a nucleic acid encoding a SMAD protein or variant thereof, so as to induce regeneration, repair and/or development of the connective tissue. This invention further provides methods of ex-vivo implantation of engineered cells into an injury, defect or condition of the connective tissue. This invention also provides a nucleic acid encoding a SMAD 8 protein variant, cells comprising such SMAD 8 variant, include mesenchymal stem cells, progenitor cells or cells derived from a connective tissue. Lastly, this invention provides SMAD 8 protein variant.

Methods of inducing or enhancing connective tissue repair

Cyclic to Synthetic pseudopeptide derivatives of osteogenic growth polypeptide (OGP) and OGP(10-14) which are capable of enhancing bone cell proliferation and bone formation. Pharmaceutical composition comprising as active ingredient at least one pseudopeptide derivative of the invention and to the use of these pseudopeptide derivatives in the preparation of a pharmaceutical composition for stimulating the formation of osteoblastic or fibroblastic cells, enhancing bone formation in osteopenic pathological conditions, repairing fractures, healing wounds, grafting of intraosseous implants, reversing bone loss in osteoporosis and other conditions requiring enhanced bone cells formation.

Synthetic peptides and pseudopeptides having osteogenic activity and pharmaceutical compositions containing the same

The invention relates to methods of enhancing repair of a cartilage and/or inducing formation of a cartilage by administering a cell which expresses a factor of the T-box family, which includes inter-alia the brachyury. In another embodiment, the invention relates to an engineered cell, which is transfected with a vector comprising a nucleic acid sequence encoding a factor of the T-box family, thereby expressing a factor of the T-box family. In another embodiment, the invention relates to compositions comprising a vector which comprises a nucleic acid sequence encoding a factor of the T-box family and in another embodiment the composition comprising cell which expresses a factor of the T-box family, which includes inter-alia the brachyury.

Methods and compositions for enhancing cartilage repair

The invention relates to synthetic pseudopeptide derivatives of osteogenic grog polypeptide (OGP) and OGP(10-14) which may be linear or cyclic, and which are capable of enhancing bone cell proliferation and bone formation. Further, the present invention relates to pharmaceutical composition comprising as active ingredient at least one pseudopeptide derivative of the invention and to the use of these pseudopeptide derivatives in the preparation of a pharmaceutical composition for stimulating the formation of osteoblastic or fibroblastic cells, enhancing bone formation in osteopenic pathological conditions, repairing fractures, healing wounds, grafting of intraosseous implants, reversing bone loss in osteoporosis and other conditions requiring enhanced bone cells formation.

A biochemically pure polypeptide(s), termed osteogenic growth polypeptide (OGP), which exhibits stimulatory effects on osteoblastic cells, in vivo bone formation and hemopoietic reconstruction. OGP, identified from regenerating bone marrow, has an amino acid sequence of
