The cells of the blood include leukocyte cells and hematopoietic progenitor cells (nucleated cell types) as well as erythrocytes and platelets (non-nucleated cell types). These blood cells are not capable of repair or regeneration of stromal or vascular tissues. Stromal and vascular cells (SVF) are nucleated cells derived from stromal and vascular tissues present in the adipose tissue matrix. The SVF cells are capable of stromal and vascular tissue repair and regeneration.
