Summary
A new scoring system, SPOT, standardizes wound healing assessment using H&E or MT staining. This validated system accurately quantifies healing dynamics across various murine wound models.
Area of Science:
- Histopathology
- Wound Healing Research
- Biomedical Science
Background:
- Accurate monitoring of wound progression is crucial for molecular studies and therapeutic efficacy evaluation.
- Current histopathological analysis lacks a standardized, reproducible scoring system for wound healing dynamics.
- Existing methods present variability and investigator bias, hindering consistent assessment.
Purpose of the Study:
- To develop and statistically validate a reproducible scoring system for assessing wound healing dynamics.
- To establish a standardized method using Hematoxylin & Eosin (H&E) or Masson's Trichrome (MT) staining.
- To define clear parameters for evaluating re-epithelization, granulation tissue, and remodeling.
Main Methods:
- Optimized and clarified wound healing parameters to minimize bias and variability.
- Compared consistency of H&E versus MT staining for parameter assessment.
- Validated the scoring system across four murine skin wound models (excisional, punch biopsy, pressure ulcers, burn wounds).
- Utilized blinded, randomized analysis by independent investigators on 54 histology sections.
Main Results:
- Developed the SPOT (Stellenbosch University, Polish Academy of Sciences, Obatala Sciences, University of Texas Southwestern) skin wound score.
- Achieved high sensitivity for each parameter, ranging from 80% to 95%.
- Demonstrated accuracy and reproducibility across different wound types and investigator groups.
- Established a scoring range from 0 (unhealed) to 12 (completely healed without excessive scarring).
Conclusions:
- The SPOT score provides a standardized and validated method for assessing wound healing dynamics.
- This system enhances reproducibility in histopathological analysis of wound biopsies.
- The SPOT score is applicable to various wound models and staining techniques (H&E, MT).
