Development and characterization of a new muscle cell culture system from Clarias magur (Hamilton, 1822).

The cell line has been used as a novel in vitro tool for executing several studies in life sciences. The current study aimed to develop and characterize a muscle cell culture system derived from Clarias magur. The primary muscle cell cultures derived from the caudal peduncle muscle have been successfully sub cultured up to 13 passages to establish a new muscle cell culture system known as CMM. At a temperature of 28 °C, L-15 medium supplemented with 20% FBS produced the maximum growth of muscle cells. However, muscle cells were optimized to grow at 10% FBS. To enhance the proliferation capacity of the CMM cells, a growth-promoting factor bFGF (10 ng/ml) was added, thereby reducing the time interval of passages for the subsequent cultures. DNA barcoding of the CMM cell culture system authenticated the species of origin. The cell culture system was successfully cryopreserved by a slow freezing procedure at - 80 °C with a revival efficiency of 60%.
