For instance , the embryo cell stops splitting after 50 times , but for a 70 - yr old man , it stops splitting after 20 - 30 times 但这时限会随年环境因素等的改变而变化,而出现衰老现象。
Another , more complex , technique takes embryo cells and develops them into a wide variety of cell types and tissues 另外一种较为复杂的技术,则是把胚胎细胞培养成各式各样的细胞种类及组织。
The tpsl gene was introguced into immature embryo cells of 12 - 16 days wheat cultivars wen . 6 via gene gun delivery technique . resistant calli were selected on medium containing hygromin ( 40 - 60mg / l ) 用基因枪将海藻糖- 6 -磷酸合成酶基因( tps1 )导入小麦栽培品种温6的12 - 16日龄的幼胚细胞中。
