Isolation of Epithelial Like Cells from the Rabbit Myometrium: the Distribution of Creatine Kinase and Plasminogen Activator

토끼 자궁근충에서 분리한 상피세포의 배양 분리 : 크레아틴 카이네이스와 플래스민 활성인자의 분포

Cells with an epithelioid morphology were isolated from the rabbit myometrium and were grown in culture. The cells had a doubling time of 53 hours when grown in the presence of 10% fetal calf serum in Basal Eagle's medium with 3mM glutamine. In the presence of estrogen plus insulin, doubling time was reduced to 40 hours. Creatine kinase activity upon reaching confluency was determined to be 0.019 unit per mg protein. Approximately 30% of the activity was extractable only in high ionic strength buffer. Cells also contained plasminogen activator with a specific activity of 140 CTA units per million cells. Creatine kinase was mainly BB form. The cells contained a cross reactive protein against bovine smooth muscle uterine anti-myosin.

가토 자궁 근충에서 분리한 상피세포를 10% 송아지혈청, 3mM glutamine이 함유한 Basal Eagle 배지에서 배양한 결과 세포 성장 시간은 53시간이 소요되었고, estrogen에 insulin을 첨가했을 때는 40시간으로 감소하였다. Creatine kinase 활성 단위는 단백질 mg당 0.019 unit이었다. 활성의 30%가 이온상태가 높은 완충액에서 추출되었고, plasminogen 활성 인자는 세포 백만당 140 CTA unit였다.
