Disclosed herein are methods and compositions for the use of marrow adherent stem cells and their descendents; e.g., bone marrow-derived neural regenerating cells; for provision of angiogenic factors to cells. In certain embodiments, provision of angiogenic factors to sites of neural degeneration stimulates growth and/or survival of host neurons.

The present invention provides a method of producing a cell mass capable of serving as a primitive organ-like structure comprised of a plurality of somatic cell types of somatic origin, comprising: preparing cultures containing the plurality of types of somatic cells; mixing the plurality of types of somatic cell cultures followed by adding a Wnt signal activator to the mixed cell culture; subjecting the culture containing the Wnt signal activator to non-plate contact culturing over a predetermined time period; and replacing the medium of the culture cultured by the non-plate contact culturing with medium not containing Wnt signal activator and further culturing for a predetermined time period; wherein, at least one type of the plurality of somatic cells is maintained in an undifferentiated state.

Compositions and methods of promoting wound healing in a human by administering to the human mesenchymal stem cells: in an effective amount

The present invention is concerned with a composition and in vitro method for generating a desired cell type and/or tissue type from hair follicular stem cells. The composition and in vitro method are particularly suitable for generating an autologous desired cell type and/or tissue type. Furthermore, the composition and method are especially efficient and suitable for use in the context of cosmetic cell and/or tissue transplantation in recipient areas of a subject experiencing cell and/or tissue loss caused by, for example, a wound, scar, burn injury, tissue degeneration, and aging. The composition and in vitro method are also suitable to circumvent complications related to infections and/or immune rejection of a cosmetic cell and/or tissue implant or graft.

Compositions and methods of promoting wound healing in a human by administering to the human mesenchymal stem cells in an effective amount.

The invention relates to multipotential expanded mesenchymal precursor progeny (MEMP's), characterised by the early developmental markers STRO-1.sup.bri and ALP. The present invention also relates to methods for producing MEMP's and to uses of MEMP's for therapeutic applications.

The present invention relates to compositions and methods utilizing hair follicle derived Non-Bulbar Dermal Sheath cells for use in the treatment or prevention of the tendon injuries.

Compositions and methods involving microspheres composed of mesenchymal cells such as dermal papilla cells (DPCs) and extracellular matrix, epithelial cell such as keratinocyte are disclosed. It has been discovered that by balancing the proportion of DPCs and extracellular matrix in the DPC-matrix mixture, and by incubating a particular range of small volume of the DPCmatrix mixture, DPC-matrix microspheres can be formed that have useful properties. Most significantly, the resulting DPC-matrix microspheres are particularly suited to be used to produce bioengineered hair follicles that have features of native hair follicles.

Disclosed herein are methods and compositions for the use of marrow adherent stem cells and their descendants; e.g., bone marrow-derived neural regenerating cells; for provision of angiogenic factors to cells. In certain embodiments, provision of angiogenic factors to sites of neural degeneration stimulates growth and/or survival of host neurons.

The present invention provides a method for manufacturing a regular and high-density regenerated hair follicle primordium aggregation similar to the hair follicle tissue of a mammal in a simple manner. A regenerated hair follicle primordium aggregation manufacturing method of the present invention includes a step of forming hair follicle primordia by inoculating a microwell plate, which includes regularly arranged microwell portions, with mesenchymal cells and epithelial cells and culturing a mixture of the cells while supplying oxygen thereto.
