Both MCC and IMCC remained serum dependence and stop proliferating in DMEM without serum. Proliferation rate of IMCC and MCC in 5% serum medium was obvious less than that in 10% and 20% serum serum medium.

• IMCC和MCC均不能在无血清培养基中生长,但可在含5%25血清的培养基中生长,其增殖速度明显低于在10%25和20%25两种血清浓度中细胞的生长速度,而10%25和20%25两种血清浓度中细胞的生长速度则较接近。
