In some of angiosperms, the zygotic division gives rise to two daughter cells with distinct morphologies and developmental fates.The apical cell develops into an embryo, and the basal cell mainly divides to form a suspensor that later completely disappears.It is still unknown when these distinct cell fates are determined and whether the basal cell fate determination and suspensor formation depend on its interaction with the apical cell or/and embryo proper.Using an in vitro microculture system along with a laser-controlled microdissection technique (LCM), we demonstrated that a single basal cell can follow basic standard embryonic pattern and develop into a filamentous suspensor.

那天，腰有些酸痛，联想到电视里铺天盖地的补肾广告，我哪敢怠慢，急颠颠地向医院跑去，找咱们的白衣天使们袪病治痛。 老医生慈眉善目，直接问：“哪儿不舒服？”我答：“腰痛。”“可能是肾的问题，拍个片吧。”我瞠目结舌——连最起码的望、闻、问、切都给省了？看他抽个单就行云流水起来，我打消了做个最基本检查的建议。要知道，进了医院听医生的准没错，医者父母心嘛。 过了一会，拿着新拍的片子去找医生。也难为他老人
