1mm
Cell CulturesCell Cultures• Wound cells can be cultured.• Form new tissue.• Mimic natural conditions.• Easy to manipulate.
100µm
ImplicationsImplications• Model system to study rapid, scar-free wound repair.• Like fetal wound repair.• Molecular genetic tools allow comparison to humans.• Biomedical discovery tool.
