ABSTRACT
BACKGROUND:
A lot of work has been carried out on the development of the primary cultured rat myocardial cel s at home and abroad. The primary culture technology of rat myocardial cel s becomes more mature, but myocardial cel s from neonatal mice are not easy to be obtained under the same experimental conditions. The mouse genome has more similarities with the human genome, which has a higher research value.OBJECTIVE:
To improve the primary culture method of neonatal mouse myocardial cel s, and to obtain myocardial cel s with high purity, vitality and original structure and function.METHODS:
The mouse cardiac tissues were treated using an enzyme digestion method to isolate isolated single myocardial cel sfirst, the cardiac tissues were digested using trypsin, and then col agenous fibers were treated with col agenase to isolate single myocardial cel s. The concentration and action time of trypsin and type II col agenase were adjusted, and the pH values of reagents and temperature of each step were strictly control ed. RESULTS ANDCONCLUSION:
At 24 hours after inoculation, the myocardial cel s began to be adherent;at 48 hours, independent pulsation of myocardial cel s could be observed;at 72 hours, myocardial cel s were cross-linked;and at 96 hours, myocardial cel s formed cel clusters and presented with consistent beating. The survival rate and purity of myocardial cel s were both over 95%. This modified method could successful y culture myocardial cel s with high purity and viablility from neonatal mice, and the structure and function of myocardial cel s could be retained. Therefore, it is a feasible culture method.
