BMV–CSC patch therapy promoted cardiomyocyte mitotic activity in the post-MI porcine heart. (A) Presence of pH3⁺ cardiomyocytes (pH3⁺α-SA⁺ double-positive cells; yellow arrowheads) in the infarcted area across different treatment groups at week 4. Quantification shows total pH3⁺ cells as well as pH3⁺ cardiomyocytes in different groups. (B) Presence of AURKB⁺ cardiomyocytes (yellow arrowheads) in the infarcted area across different treatment groups at week 4. Quantification shows total AURKB⁺ cells as well as AURKB⁺ cardiomyocytes in different groups (n = 3). Scale bars, 20 μm.
