초록

For efficient production of cultured meat, chicken breast muscle cells and chicken leg muscle cells were proliferated and differentiated using medium with various serums, and proliferation and differentiation ability were analyzed. Chicken breast muscle cells and chicken leg muscle cells were cultured with serum-free medium (NC), medium with 20% FBS (C), medium with 10% chicken serum (CS) and 5% horse serum (HS) (T1), medium with 10% CS (T2), medium with 5% HS (T3).Using the immunofluorescence staining, Pax7 and nuclei were stained in chicken breast muscle cells and chicken leg muscle cells to confirm that they were muscle satellite cells. As a result of cell counting, both cells cultured in T1 medium proliferated the most. Chicken breast muscle cells and chicken leg muscle cells were subcultured from passage 1 to passage 6 using T1 medium. In both cells, viability and number of live cells decreased with increasing passage, but chicken leg muscle cells had higher viability and number of live cells than chicken breast muscle cells in all passages. Cells were differentiated using differentiation medium containing 10% chicken serum and 5% horse serum for each passage. It was confirmed that the differentiation ability of chicken leg muscle cells was more maintained as passage increased than chicken breast muscle cells. Therefore, it is considered that the results of chicken cells will become the basic data for the development of cultured meat.
