胚胎发育

Apolipoprotein D is a member of the lipocalin family. ApoD can bind small hydrophobic molecules such as cholesterol and arachidonic acid, etc. It also plays a role in many physiological and pathological processes such as development and differertiation of embryo, apoptosis of cancer cells, immune defense, and so on.

载脂蛋白D属于脂蛋白家族，和该家族的其它成员一样，其基本功能是转运一些脂类的小分子物质，还参与胚胎的发育、分化；肿瘤细胞的发生、发展和凋亡；免疫性反应；抵抗外界环境胁迫以及神经系统的发生和损伤修复。

Apomixes is comparable to the conditions of apogamy and apospory, which are seen in many ferns.
