ClinConnect Summary

Wound healing for Stage III and IV pressure ulcers or diabetic foot ulcers can take four to six weeks or longer and cost upwards of $40,000 to treat. Past studies have shown that adipose tissue contains progenitor cells or regenerative cells that can release multiple angiogenic growth factors and cytokines including vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF) and chemokine stromal cell-derived factor-1 (SDF-1). A current literature review revealed that there is research related to use of stem cells to enhance wound healing, in particular with ischemic or radiat...
