| abstract |
The present invention relates to compositions comprising stem cells and partially committed progenitor cells and to methods of controlling cell proliferation and differentiation, which can be used for expansion of stem cells and their subsequent differentiation. The present invention provides expanded population of essentially undifferentiated stem cells, which are useful in clinical procedures involving stem cell therapy, and a population derived thereof of which at least part of the cells are differentiated. The cells can be used per se, as a part of a cell-bearing composition comprising cross-linked hyaluronic acid-laminin gels or as a part of a composite implant for tissue regeneration. |
