Abstract
The ultrasturcture of the cell nucleus and perinuclear cytoplasm in Acetabularia is quite different in young and old cells. When a nucleus of an old cell was implanted into the cytoplasm of a young cell the nucleus assumed the morphology typical of a young cell within less than 10 days. The cytoplasm of an old cell was able to induce the reverse change in an implanted nucleus from a young cell. This cytoplasmic induction of nuclear ageing appeared to proceed more rapidly than rejuvenation.
摘要
伞藻细胞核及核周细胞质的超微结构在幼细胞和老细胞中差异很大。将老细胞的细胞核植入幼细胞的细胞质中，该细胞核在不到10天的时间内就呈现出幼细胞典型的形态。老细胞的细胞质能够使植入的幼细胞核发生相反的变化。这种细胞质对细胞核衰老的诱导似乎比细胞核恢复活力的过程进行得更快。
