닭 혈청을 포함한 배양액 조성 변화가 QM7 메추리 근육세포의 성장 및 분화에 미치는 영향 분석

초록

QM7 cell, a quail muscle cell line, has been used in various studies. In cell culture, it is well known that the culture medium has a significant influence on cell growth and maintenance of cell characteristics. This study aimed to adjust the culture medium to make it more suitable for QM7 muscle cells. A culture medium was prepared by adding 2% chicken serum (CS) instead of 10% tryptose phosphate broth (TPB) to the conventional culture medium. In the culture medium prepared with CS, the QM7 muscle cells changed from a pointed, thin to a broader shape. In addition, they grew and divided more rapidly in the new culture medium than in the conventional culture medium. The number of cells increased faster in the CS-containing culture medium from day two after passaging, and significantly increased from day three. The muscle cells grown in the medium containing CS maintained their undifferentiated state prior to differentiation. Myotubes formed well when the cells were maintained in CS-containing medium, resulting in a longer length and uniformity. According to the above results, it is clear that the culture of QM7 myocytes using a medium containing CS rather than TPB helps obtain better results in cell maintenance and differentiation.
