真核生物(eukaryotes)以有丝分裂(mitosis)的方式进行cell division。 Cell division对于生命体而言很重要,表现为以下几个方面: 1. Growth 多细胞生命体的生长离不开mitosis,从受精卵发育成一个多细胞生命体自然需要通过mitosis增加细胞数目。 2. Replacement of cells and repair of tissues 以人体为例,皮肤细胞和消...

染色体分离错误可导致细胞死亡和癌症发展。研究人员发现着丝粒由两个亚结构域组成。这一基本发现对染色体分离过程具有重要意义,并为癌细胞错误分裂提供了新的机制。这项研究于近期发表在《Cell》杂志上,文章题为“Vertebrate centromeres in mitosis are functionally bipartite structures stabilized by cohesin”。 我们的身...
细胞分裂(cell division)是生物体持续生长、更新细胞以及进行繁殖的关键过程。原核生物通过二分裂(binary fission)进行细胞分裂，而真核生物则通过有丝分裂(mitosis)这一更为复杂的过程实现细胞分裂。细胞分裂的重要性体现在多个方面。首先，它促进了多细胞生物体的生长，从受精卵到形成一个复杂的多细胞生命...
相关研究结果于2024年5月13日在线发表在Cell期刊上,论文标题为“Vertebrate centromeres in mitosis are functionally bipartite structures stabilized by cohesin”。 我们的身体由数万亿个细胞组成,其中大多数细胞的寿命有限,因此必须进行增殖以取代旧细胞...
Cell - Mitosis, Cytokinesis, Prokaryotes: In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Survival of the eukaryotes depends upon interactions between man
有丝分裂指数(mitotic index)指一个细胞群体中正在进行有丝分裂的细胞的百分数(number of cells containing visible chromosomes (in mitosis) divided by the total number of cells in field of view),可以用来区分良性和恶性肿瘤(benign and malignant tumours)。
Stamatov et al. introduce Facilitated Segmentation and Tracking of Chromosomes in Mitosis Pipeline (FAST CHIMP), which combines time-lapse super-resolution microscopy with deep learning to study chromatin dynamics in live cells. Rumen Stamatov
cell division主要由两个大步构成:interphase 和mitosis/meiosis •Interphase -- G1, S, G2 --in G1, cell grows to normal size (normal functions are carried out. Protein synthesis) --in S, DNA replication ∴each chromosome is made of two identical chromatids ...
