| Research Abstract |
Intractable skin ulcers are often caused by ischemia, and in the practice, most patients are elderly people. Therefore, we made monolayered mesenchymal cell sheets with the ability of angiogenesis, derived from subcutaneous adipose tissue of young and aged rats. And young rats with wounds were divided two groups, grafted young cell sheet(group Y)and grafted aged one(group A). We evaluated the effect of treatment as wound area and wound blood flow. Group A was inferior to group Y, but was better than wounds without cell sheet grafting. This finding suggests that it is possible to use cells derived from elderly people as treatment, but the improvement is necessary to reach young cells.
