1.In vitro, ES cells can spontaneously aggregate into the formation of embryoid bodies (EBs) comprised of a range of differentiated cells.
体外，ES细胞能自发聚集形成胚胎体（EB），分化成许多种细胞类型；
2.Low temperature pretreatment had a significant effect for embryoid yield, different genotype had different pretreatment time .
低温预处理对小孢子胚产量有显著影响，不同基因型所需预处理时间不同。
3.However, the embryoid yield trended to decline with the prolongation of pretreatment time of inflorescences.
但随着花序处理时间的延长，小孢子产胚率有下降的趋势。
4.All the materials microspore embryoid yield had significant improvement under low temperature pretreatment.
供试材料经低温预处理，小孢子胚产量均有明显提高。
5.The result showed that the pretreatment with high temperature was simple and operational, and the largest number of embryoid was obtained.
结果表明：高温预处理穗子不仅简便易行，可操作性强，而且得到的胚状体最多。
6.Kinetin was later shown to be inhibitory for embryoid formation .
激动素原来被表明抑制胚状体的形成。
7.The embryoid induction ability of normal bolting genotypes were higher than easy bolting and hard bolting genotypes .
较易抽薹型材料的产胚能力大于易抽薹型和不易抽薹型。
8.Objective To explore the residual undifferentiated mouse embryonic stem cells (ESCs) in embryoid bodies.
