In part one, we treated grainy fat with leptin, saline and MEM before subcutaneous grafting. After 10 days, the weight-maintence of the grafted tissue was 108.3% in the group which 0.6g tissue was processed with 20ng/ml leptin.

• 用10ng/ml及20ng/ml瘦素、生理盐水、MEM组织培养液处理自身颗粒脂肪后皮下移植，结果显示20ng/ml瘦素处理的0.；6克颗粒脂肪组织，移植10天后的重量维持率达108
