This requires cell cycle control and often maintenance of multipotency or pluripotency, depending on the stem cell. 3 v( l* _3 t6 J0 p $ O3 ?: x& }0 r- F这一(自我更新)过程（的实现）要有对细胞周期的控制，并常涉及多能性的维持（mutipotency or pluripotency，根据不同的干细胞而定）。, G) N( L, M. w- x1 ^9 Z
# {7 [. h5 O) w: v/ U2 [* x' Kcell cycle control和maintenance of都是requires的宾语，often是用来修饰maintence的，意思是“往往”也需要（在自我更新过程中）维持多能性。 ! o. u( X" |6 E) c9 M2 V1 L3 G: O! M" m1 V9 b$ j
先把句型结构搞清楚了，理解就容易些了。这是个带两个并列宾语的结构。完全展开的话就是： # e- u3 H% n; D' v" b5 ^! Z 7 R& r8 z/ D+ j9 ~. y* b1 G; VThis requires cell cycle contro, and often requires maintenance of multipotency or pluripotency (which depends on the stem cell types).
