[The capacity for regeneration of the myocardium in rat fetuses].
A reproducible model of heart injury in 16-days old rat fetuses has been developed. 30 days after the injury a 4-fold increase of the damaged area was observed. Decrease of reparative capacity of myocardium in fetuses as compared with the adults is due to the functional immaturity of the connective tissue cells.
