Laboratory Models for the Study of Normal and Pathologic Wound Healing

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Cell Biology

Background:

• Current wound healing research relies on diverse in vitro and in vivo models.
• In vitro models facilitate detailed examination of specific cell types.
• In vivo models offer a comprehensive view of biological responses like inflammation and angiogenesis, including crucial cell-cell interactions.

Purpose of the Study:

• To review and delineate the most relevant wound healing models.
• To discuss the advantages and disadvantages of each model.
• To assist researchers in selecting optimal models for experimental design, testing, and validation.

Main Methods:
