초록

본 연구는 여러 CLA 이성체, 즉 cis-9, cis- 11(c9c11), cis-9, trans-11(c9t11), trans-9, trans-11 (t9t11) 및 trans-10, cis-12(t10c12)가 배양 중인 돼지 지방세포와 근육세포의 분화와 증식에 미치는 영향을 구명하고자 실시하였다. 세포는 신생자돈으로부터 분리했다. t10c12 이성체는 지방세포의 분화를 억제했는데(92%) 근육세포의 분화는 억제시키지 않았다. t9t11 이성체는 지방세포의 분화를 억제했는데(14%), 근육세포의 분화는 촉진시켰다(26%). 다른 CLA 이성체는 지방세포나 근육세포의 분화에 영향을 미치지 않았다. 그리고 CLA가 지방세포와 근육세포의 증식에 미치는 영향은 분화에 미치는 영향에 비해서 작았다. 위의 결과는 여러 CLA 이성체는 돼지 지방세포와 근육세포의 분화에 다른 영향을 미침을 나타낸다.

The current study was undertaken to determine the effect of conjugated linoleic acid(CLA) isomers, cis-9, cis-11(c9c11), cis-9, trans-11(c9t11), trans-9, trans-11(t9t11), trans-10, cis-12(t10c12) on differentiation of pig preadipocytes and myogenic satellite cells during culture. Cells were isolated from new born pigs. The t10c12 isomer decreased differentiation of pig preadipocytes(92%), but not that of myogenic cells. The t9t11 isomer decreased differentiation of preadipocytes(14%) and increased that of myogenic cells (26%). No other CLA isomers affected differentiation of preadipocytes or myogenic cells. The effects of CLA on proliferation of preadipocytes and myogenic cells were small, compared to the effects on differentiation. These results suggest that CLA isomers have different effects on differentiaton of pig preadipocytes and myogenic cells.
