BACKGROUND: At present, studies show that a kind of stem cell community which in many kinds of organizations can differentiate into tissue cells of different embryonic layers; but those are different from embryonic stem cells, embryonic stem cell will lose the part differentiation potential gradually during the development of pregnancy, and will present some special phenotypes or the molecular markers, as CD105 and so on, will call it postembryonic pluripotent stem cells.

背景：目前研究认为在胚胎发育后的多种组织中存在一类干细胞群体，可分化为不同胚层的组织细胞；但又不同于胚胎干细胞，随着妊娠期间胚胎的发育胚胎干细胞会逐渐失去部分分化潜能，会出现一些特殊表型或分子标记，如CD105，称其为胚胎后亚全能干细胞。

The addition of malt extract and glutamine could inhibit non-embryonic calli, and make the culture be mainly composed of embryonic calli; change of the 2,4-D concentration in liquid culture medium could adjust the status of embryonic calli to the suitable developmental stage for protoplast isolation.

通过麦芽提取物和谷氨酰胺两种物质的添加，可以起到抑制非胚性愈伤生长的作用，使培养物主要以胚性愈伤为主；通过液体培养基2，4-D浓度的改变，可调节胚性愈伤处于合适的发育时期，便于原生质体的分离。
