Scope and Objectives

Objectives: Objective of this project was to examine the efficacy of the hybrid hydrogel scaffold on burn wound animal model , which will further be translated to human patients due to biocompatible nature of its constituents (Phase I clinical Trials ). The idea is to provide a substitute alternative for patients own skin grafting or cadaver skin application. The proposed scaffold will become part of the skin will act as a skin substitute. We hypothesize that it will take 3-4 weeks to completely heal patients with surgically created donor areas by harvesting graft and flaps.

Deliverables

Bio inspired Scaffold for 2nd Degree burn wounds and Trauma care. Scaffold can be fabricated in different size and dimension as needed. Depending on depth of the burn wound hydrogel based scaffold will be manipulated and applied. Suturing can be performed to retain the scaffold over the wound bed. Semi wetted scaffold will be applied on the wound bed and will be covered with a polymeric membrane which will provide aeration to the wound. We hypothesized that the proposed scaffold will provide an alternative to autologous skin grafting as well as substitute to cadaveric skin grafting too. Thus it will act as skin substitute

Results and outcome till date

The analysis of blood parameters & histopathology of tissue and organs of Wistar rats has revealed that their is no toxicity associated with the scaffold and proven its efficacy to marketed scaffold . The ELISA studies of serum of Wistar rats related to collagen markers has shown their up- regulation . C3a, TNF alpha and IL-1 alpha studies on serum samples were comparable to marketed scaffold

Societal benefit and impact anticipated

The proposed scaffold will provide an alternative to autologous skin grafting as well as substitute to cadaveric skin grafting too. Thus it will act as skin substitute

Next steps

1 Gamma Sterilization stability on the scaffold . Comparative studies on Pre and Post sterilization by Gamma on the scaffold has been initiated
2. Ethical Approvals have been obtained to conduct experiment on 2nd degree Burn wound model of rat.
3. Animal Experimentation studies ( Burn Wound ) will be initiated after the scaffold is validated for sterilization stability.

Challenges faced

Gelatin procurement from Sigma during first year was impossible as they had stopped its supply to India. Equipment procurement and animal Ethical approvals took lot of time

Other information

The Biocompatibility studies under ISO 10993 is being evaluated by a GLP lab . The results will be completed by August end
