confluent：融合

以往的研究显示:在株化肝细胞研究中,培养肝细胞是在融合(confluent)状态下不经传代地连续培养一定时间才可见胶原生成(3),原代培养肝细胞经约5~7天的培养始有胶原合成功能的活化,原代培养的肝细胞随着培养时间延长,

dedifferentiation：反分化

研究发现单层贴壁培养软骨细胞经反复传代后(通常自第3代起),其分化特征将逐渐丧失,即出现软骨细胞"反分化"(dedifferentiation)现象[3],因而限制了体外培养软骨细胞的数量.

degeneration：衰退

第五节菌种的衰退、复壮和保藏菌种的衰退和复壮衰退(degeneration):菌种的特性发生了负变,如生长速度减慢、代谢产物合成能力下降. 菌种衰退的原因:自发突变. 衰退的防止:控制传代次数;创造良好的培养条件;利用不易衰退的细胞传代;

subculture：再培养

这个过程就称为传代(passage)或者再培养(subculture). 对单层培养而言,80%汇合或刚汇合的细胞是较理想的传代阶段. 传代培养:当原代培养成功以后,随着培养时间的延长和细胞不断分裂,一则细胞之间相互接触而发生接触性抑制,

subculture：传代培养

从体内取出组织接种培养到第一次传代,随不同的组织时间长短不一,一般为1~4w 2.传代培养(Subculture)阶段:或称继代培养. 也就是细胞系(Cell line)阶段,细胞增殖旺盛,一般细胞可传代10-50代).
