common areas may include the thigh and back area of the patient to provide an adequate amount of cells for injection into the penile tissue for treatment of peyronie 39 s adipose tissue in an amount in the range of about 60 cc to about 120 cc is obtained from the patient if desired a portion of the adipose tissue is set aside for preparing a u201c cell matrix u201d which can be remixed with an enriched population of cells from the adipose tissue in some modes of practice adipose tissue is processed to separate the adipose derived stem cells from the other material including other cellular and non cellular material in the adipose tissue preparation methods can include steps of washing the tissue treating the tissue with collagenase or trypsin or optionally with mechanical agitation liposomes which are generally aggregated can be separated from free stromal cells which include the stem cells and other cells such as red blood cells endothelial cells and fibroblast cells by centrifugation erythrocytes can be lysed from the suspended pellet and the remaining cells can be filtered or centrifuged optionally cells may be separated by cell sorting or separated immunohistochemically methods for the preparation of adipose derived stem cells are described in commonly assigned application number wo 20091120879 in other modes of practice the adipose tissue is processed to remove partially or substantially non cellular components and to form a heterogenous cell mixture the heterogenous cell mixture can include endothelial cells endothelial precursors and progenitors mesenchymal stem cells vascular smooth.
