CellCognition uses a computational pipeline which includes image segmentation, object detection, feature extraction, statistical classification, tracking of individual cells over time, detection of class-transition motifs (e.g. cells entering mitosis), and HMM correction of classification errors on class labels.
The mitosis process in the cells of eukaryotic organisms follows a similar pattern, but with variations in three main details. "Closed" and "open" mitosis can be distinguished on the basis of nuclear envelope remaining intact or breaking down. An intermediate form with partial degradation of the nuclear envelope is called "semiopen" mitosis.
These neurons are unable to enter mitosis and are stuck in a 4C DNA content state. Cell cycle re-entry by p75NTR is not dependent on Cdk4/6 (Morillo et al., 2012) and, therefore, differs from other cell types that re-enter the cell cycle.
Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis). The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart. The cell cycle in eukaryotes: I = Interphase, M = Mitosis, G 0 = Gap 0, G 1 = Gap 1, G 2 = Gap 2, S = Synthesis, G 3 = Gap 3.
A cellular model is a mathematical model of aspects of a biological cell, for the purposes of in silico research. Developing such models has been a task of systems biology and mathematical biology .
Prophase is the first stage of mitosis in animal cells, and the second stage of mitosis in plant cells. [10] At the start of prophase there are two identical copies of each chromosome in the cell due to replication in interphase. These copies are referred to as sister chromatids and are attached by DNA element called the centromere. [11]
Between 2004 and 2009, Peters also coordinated the EU funded research project MitoCheck, aimed at the identification of genes that play a key role in the process of mitosis. Between 2010 and 2015, he headed the follow-up project MitoSys, through which biologists, mathematicians, biochemists and biophysicists collaborated to reveal how genes and ...
Davis's post-doctoral research focused on Calmodulin in budding yeast [4] [5] After starting her own lab at the University of Washington, she discovered that Calmodulin performs an essential function in the yeast spindle pole body, [6] beginning the lab's gradual transition into the study of mitosis. The Davis Lab has published extensively on ...
