First phase of the meiotic or mitotic cell division (M phase), during which chromosomes condense. In meiosis, prophase occurs before meiosis I and is divided into the leptotene, zygotene, pachytene, diplotene, and diakinesis stages. Residual body An anucleate cytoplasmic structure remaining after...
However, inferring the cell division tree of a massive number of cells is a challenging problem. In addition to the computational complexity of inferring the lineage tree itself, the quality of the barcode data has posed a further challenge to this problem12. First, the number of target sites,...

Stem cellscontained within a niche often undergoasymmetric cell divisionto produce one daughter cell that differentiates and another daughter cell to maintain the stem cell population. The signals that affect each of the two daughters are different, and can either arise from anintrinsic asymmetrybetween...
The S phase (i.e., DNA synthesis stage), refers to the period from the beginning to the end of DNA synthesis. During this period, DNA replication and transcription, as well as protein synthesis, are completed. Hence, more cells in S phase indicates active cell division [47]. In ...
a The division of a bacterial cell occurs mainly through binary, or transverse, fission. Binary means that one cell becomes two, and transverse refers to the division plane forming across the width of the cell. 一个细菌细胞的分裂主要通过双发生或者横向,分裂。 双意味着一个细胞成为二,并且横向提...
Therefore, it is most likely that p53 stops mitosis to prevent cell division. Osmosis is the movement of water across a selectively permeable membrane, respiration is the process of converting glucose into energy, and mutation refers to changes in the DNA sequence. None of these processes are ...
The interaction between KCs and HSCs requires more in-depth research and has practical clinical significance. HSCs secrete many factors that regulate cell proliferation and division and participate in all aspects of regeneration, including initiation, maintenance and termination [33, 95, 96]. Further...
Increasing neural stem cell division asymmetry and quiescence are predicted to contribute to the age-related decline in neurogenesis. Cell Rep. 25, 3231–3240.e8 (2018). Article CAS Google Scholar Harris, L. et al. Coordinated changes in cellular behavior ensure the lifelong maintenance of the...
Intercellular surface tension extends and adapts the concept of tissue surface tension at the cellular level to explain cell shape and the geometry of contacting cells, such as in an epithelium. Cell shape is mainly controlled by two opposing systems: intercellular adhesion that increases the surface...
