Table 2 Histopathologic muscle regeneration scale

From: Myogenic progenitor cell transplantation for muscle regeneration following hindlimb ischemia and reperfusion

Muscle regeneration scale for histopathology
0 No signs of muscle regeneration
1 Mild signs of muscle regeneration
2 Moderate signs of muscle regeneration
3 Severe signs of muscle regeneration
Histological signs of muscle regeneration include:
• Cytoplasmic basophilia (early after damage)
• Presence of myoblast/myotubes
• Rows of internal, centrally located nuclei
• Vesiculated nuclei with prominent nucleoli
