Sarcomeric organisation of cardiomyocytes is deteriorated near the amputation site.... In contrast, at the site of amputation, the sarcomere organisation was completely disorganised at 1 dpa, lost at 7 dpa, partially recovered but not completely at 6 mpa and 11 mpa respectively (compare...
Long-term monitoring reveals persisting fibrotic scar in adult frog hearts after cardiac amputation.... Black arrows indicate amputation sites; faint blue staining formed a clot around the ventricle at 1 dpa; note the presence of a low to intense red-stained scar at the site of amputation for 1 mpa and 6 mpa respectively....
Whole-mounts of stage 53 and stage 57 xenopus hindlimbs from 0 hours to 5 days post-amputation (pa) stained by enzyme histochemistry for myeloperoxidase (mpo), a marker for neutrophils and macrophages.Only background staining is visible at the time of amputation (0 hPA), but by 6 hPA in limbs of both stages the number of brown MPO+ cells increase greatly near the site of amputation....
Histology and micro-ct of animals with variations in technical design.... Red Arrow: Ectopic (beyond plane of amputation) calcified tissue formation Green Arrow: Calcified tissue behind site of amputation White Arrow: Calcified Tissue at the site of amputation.
