Cell Bandages for Tissue Repair in Diabetic Wounds

Wound healing in diabetic conditions is severely impaired and is a major cause of extremity amputation. A cellular, tissue engineered, wound-healing product comprising of a novel matrix of electro-spun Polycaprolactone-Gelatin nano-fiber scaffold (PCG) with embedded Bone Marrow or Peripheral Blood-derived endothelial progenitor cells (BMPC) system has been developed by scientists at NCCS, for accelerated and fibrosis-free wound healing in diabetic conditions.

This system promotes selective growth of BMPCs in the wounded area and works as a combined growth and delivery system for direct application onto wounds. This system can be developed into bandage style scaffolds for a ready-to-use cell therapy product. It has several advantages including:

  • Treatment of non-healing ulcers in diabetic or burns patients,
  • Fibrosis-free healing,
  • Direct application onto skin repair sites including diabetic wounds,
  • Bio-compatible,
  • Easy handling in clinical settings,
  • Cryopreserved for long shelf life; and
  • Autologous cells can be used in the scaffold to reduce risk of rejection.

Technology Readiness: TRL B2 (In-vitro + In-vivo efficacy/ results demonstrated)

Technology Status: Patent Filed in India.

Technology Availability: Know-how available for transfer/ co-development with partners.
