In certain aspects, the invention relates to cell delivery compositions comprising a chondrogenic cell and a targeting moiety. Such compositions may be used, for example, in administering a targeted cell therapy to a subject.

Whether or not a sample of skin or of a skin equivalent contains such amount of a papillary fibroblast population as to be considered a normal skin is determined by labelling said skin or skin equivalent with at least one antibody specific for papillary fibroblasts and evaluating the extent of such labelling as a marker for skin or skin equivalent quality.

Antibodies specific for papillary fibroblasts as markers for skin quality

For repair of cartilage damaged as part of the degenerative effects of osteoarthritis, the inventors have found that the human mesenchymal stem cell approach makes it possible to: (1) regenerate both shallow cartilage chondral defects and full thickness cartilage defects (osteochondral lesions); (2) broaden the suitable clinical population to routinely include middle-aged patients; (3) eliminate the use of autologous tissue grafts (mature cartilage and the periosteal covering) to repair an articular cartilage injury; (4) regenerate other types of injured cartilage such as patellar and spinal disk cartilage; (5) regenerate articular joint cartilage in older patients with osteoarthritis; and (6) form new cartilage and subchondral bone which fully integrate into the adjacent normal tissue.

A multilayer skin equivalent is formed having a scaffold layer containing dermis-forming cells, and a keratinocyte layer. The dermis-forming cells and keratinocytes are preferably autologous, and the dermis-forming cells can be human mesenchymal stem cells (MSCs), dermal fibroblasts (e.g., papillary or reticular dermal fibroblasts) or mixtures thereof. The scaffold is preferably type I collagen alone, or types I and II collagen in combination. Also formed is a multilayer skin equivalent having a scaffold layer containing a layer of extracellular matrix component containing papillary dermal fibroblasts in laminar relationship with a layer of extracellular matrix component containing reticular dermal fibroblasts, and a keratinocyte layer. A multilayer dermal equivalent is provided having a layer of extracellular matrix component containing papillary dermis-forming cells and a layer of extracellular matrix component containing reticular dermis-forming cells. In another embodiment, the dermal equivalent has a layer containing MSCs and a layer selected from a layer of extracellular matrix component containing papillary dermis-forming cells and a layer of extracellular matrix component containing reticular dermis-forming cells, and optionally a keratinocyte layer. In the skin and dermal equivalents, at least one layer may contain an agent that promotes adhesion or angiogenesis. Also present may be a bioactive agent that enhances proliferation, commitment or differentiation of mesenchymal stem cells into dermal components, either in vitro or in vivo. An injectionable composition is also provided containing dermis-forming cells and an extracellular matrix component in a pharmaceutically acceptable injectable carrier.

Biological material for the repair of connective tissue defects comprising mesenchymal stem cells and hyaluronic acid derivative

An implant for repair of a tissue defect comprises a plurality of physiologically compatible load-bearing sutures for securing under tension tissue adjacent to the defect to be repaired, the sutures for supporting a tissue reparative cell mass in the defect and a tissue reparative cell mass supported thereby. The sutures have a central portion encapsulated in a cell containing matrix which is contracted under a tensile load by the cells thereof and formed into a mat sheet during the contraction. Spring metal wires hold the sutures in tension during the contraction. The matrix is a collagen gel or other material which the cells contract, the cells comprising human mesenchymal stem cells. The mat sheet is then rolled into a spiral roll with the sutures extending from opposite roll ends to form the desired implant. Different embodiments are disclosed.

Biomatrix for soft tissue regeneration using mesenchymal stem cells

The invention relates to isolated human mesenchymal stem cells, a method for isolating, purifying, and culturally expanding human mesenchymal stem cells (i e. mesenchymal stem cells or 'MSCs'), and characterization of (including by cytokine expression profiling) and uses, particularly research reagent, diagnostic and therapeutic uses for such cells. The stem cells can be culture expanded without differentiating. Further disclosed are monoclonal antibodies specific for human mesenchymal stem cells and the monoclonal hybridoma cell lines (ATCC nos. 10743-10745) that synthesize and secrete these monospecific antibodies, and uses of the monoclonal antibodies for diagnostic and/or therapeutic purposes.

Methods for in vitro or ex vivo lineage directed induction of isolated, culture expanded human mesenchymal stem cells comprising contacting the mesenchymal stem cells with a bioactive factor effective to induce differentiation thereof into a lineage of choice as well as such compositions including isolated culture expanded human mesenchymal stem cells and bioactive factors effective to induce directed lineage induction are disclosed. Further disclosed is this method which also includes introducing such culturally expanded lineage-induced mesenchymal stem cells into a host from which they have originated for purposes of mesenchymal tissue regeneration or repair.

An implant for repair of a tissue defect which implant comprises a physiologically compatible load-bearing member having an element for securing under tension tissue adjacent to the defect to be repaired, an element for supporting a tissue reparative cell mass in the defect and a tissue reparative cell mass supported thereby. The implant can be a suture material having a cell containing matrix surrounding a central portion thereof. The matrix is preferably a gel or other material which the cells cause to contract, thereby drawing together the tissues surrounding the defect to which the implant is attached.
