Autologous tissue patch rich in stem cells created in the subcutaneous tissue

Figure 3 Bladder-like de novo tissue obtained 14 d after injecting a slurry of poldextran gel particles in the subcutaneous space of a rat. A: The bladder-like tissue enclosed the injected gel particles; B: By piercing the balloon-like tissue the polydextran particles could be removed from the tissue to deflate the bladder. The tissue could then be used in a variety of ways including as a cusp for cardiac valve repair after cutting it appropriately to the required curvature.
