Adipose-derived stem cells for tissue regeneration and wound healing
Compositions and methods for promoting tissue regeneration, particularly skin regeneration, with adipose-derived stem cells are provided. Additionally methods and compositions for promoting tissue regeneration with adipose-derived stem cell side population cells are provided. The adipose-derived cells are administered in a tissue regenerating effect amount optionally with a bioactive agent. Additionally the adipose derived cells can be autologous or syngeneic.
1. A therapeutic composition for promoting tissue regeneration in a mammal comprising isolated adipose-derived stem cell side population (ADSC-SP) cells, wherein said side population consists essentially of cells having the phenotype Lin − , Sca-1 + , CD90 + , CD34 low , CD13 low , CD117 − and CD18 low .
2. The therapeutic composition of claim 1 further comprising a pharmaceutically acceptable carrier.
3. The therapeutic composition of claim 1 wherein said mammal is a human.
4. An isolated mammalian adipose derived stem cell side population (ADSC-SP) wherein said isolated ADSC-SP cells comprise a subpopulation isolated from adipose-derived stem cell main population cells, and said isolated ADSC-SP cells consist essentially of cells having the phenotype Lin − , Sca-1 + , CD90 + , CD34 low , CD13 low , CD117 − and CD18 low .
5. The isolated mammalian ADSC-SP of claim 4 wherein said mammal is a human.
