Application of Human Adipose Stem Cell (hADSC) in Collagen Gel on Rat Deep Dermal Burn

摘要

Human adipose derived stem cells (hADSC) is expected to be an efficient solution for healing deep-dermal burns that help in wound closure. This study used 20 male Sprague dawley rats. Each rat received three wounds with different treatments (control, hADSC in collagen gel and collagen gel). Wound closure was observed at day 7th, 14th, 21th and 28th (sacrificed day) macroscopically, wound areas were measured and collagen densities were evaluated. Reduction of wound area showed significant difference between hADSC in collagen gel group and control group (p 0.001) and between hADSC in collagen gel group and collagen gel group. The hADSC in collagen gel group had a higher collagen density compared to control and collagen gel group. Application of hADSC in bovine collagen gel in rat deep-dermal burn models provided faster and better wound healing compared with control and bovine collagen gel group.
