The present invention provides adipose-derived stem cells (ADSCs), adipose-derived stem cell-enriched fractions (ADSC-EF) and adipose-derived lattices, alone and combined with the ADSCs of the invention. In one aspect, the present invention provides an ADSC substantially free of adipocytes and red blood cells and clonal populations of connective tissue stem cells. The ADSCs can be employed, alone or within biologically-compatible compositions, to generate differentiated tissues and structures, both in vivo and in vitro. Additionally, the ADSCs can be expanded and cultured to produce molecules such as hormones, and to provide conditioned culture media for supporting the growth and expansion of other cell populations. In another aspect, the present invention provides an adipose-derived lattice substantially devoid of cells, which includes extracellular matrix material from adipose tissue. The lattice can be used as a substrate to facilitate the growth and differentiation of cells, whether in vivo or in vitro, into anlagen or even mature tissues or structures.

There is disclosed a method of combining mesenchymal stem cells (MSCs) with a bone substrate. In an embodiment, the method includes obtaining tissue having MSCs together with unwanted cells. The tissue is digested to form a cell suspension having MSCs and unwanted cells. The cell suspension is added to the substrate and the MSCs are allowed to adhere. The substrate is rinsed to remove unwanted cells. In an embodiment, there is disclosed an allograft product including a combination of MSCs with a bone substrate made according to the described method. Other embodiments are also disclosed.

The present invention provides methods and compositions for the production of glial cells and oligodendrocytes from placenta stem cells. The invention further provides for the use of these glia and oligodendrocytes in the treatment of, and intervention in, for example, trauma, ischemia and degenerative disorders of the central nervous system (CNS), particularly in the treatment of demyelinating diseases such as multiple sclerosis.

A method is disclosed for preparing a soft tissue site, and augmenting the soft tissue site, such as the breast(s), scar, depression, or other defect, of a subject through use of devices that exert a distractive force on the breast(s) and grafting of autologous fat tissue such as domes with sealing rims for surrounding each of the soft tissue site and a regulated pump. The method for preparing the soft tissue site, and enhancing fat graft results, entails application of the distracting force to the targeted soft tissue site at least intermittently for some period of time and preferably several weeks prior to the graft procedure. A related aspect of the invention includes following the preparation steps by transfer of fat from other areas of the subject to the subject's soft tissue site, and then reapplication of the distractive force to the soft tissue site that received the autologous fat graft. Alternatively, fat from genetically related sources may be used, and the fat may be further processed prior to injection. Substantial soft tissue augmentation, high rates of graft survival and negligible graft necrosis (data demonstrating 80% survival and only 20% necrosis is presented) or calcification result from the practice of these methods.
