  • Germ
  • Here we show that changes in the stem cell orientation with respect to the niche during ageing contribute to the decline in spermatogenesis in the male germ line of Drosophila . (nature.com)
  • Microtubules
  • Microtubules pull each homologue to opposite sides of the cell. (encyclopedia.com)
  • The "help" which Topo2 receives comes from the microtubules, a type of tiny wire that makes up part of the mitotic spindle, a structure similar to a rugby ball that is created when the cell begins the process of duplication and division. (eurekalert.org)
  • process
  • Cell division is the process by which a parent cell divides into two or more daughter cells. (wikipedia.org)
  • The process is akin to two children dividing up their Halloween candy: collect your candy, pile it in the middle, and divide it into two equal portions. (redorbit.com)
  • The discovery reveals that, when disturbed, this process could contribute to cancer or other diseases by failing to properly control the steps and timing of cell division, the researchers say. (medindia.net)
  • The researchers' next steps are to examine select proteins modified by O-GlcNAc and found at locations important for various steps in cell division to figure out why an imbalance of O-GlcNAc on the cells' proteins has such a dramatic effect on the process. (medindia.net)
  • The process continues throughout your life to grow new cells and replace damaged ones. (abpischools.org.uk)
  • control
  • Cells do not usually proliferate out of control, because they only divide in response to a signal that they receive from the outside. (innovations-report.com)
  • Cell size is found to be an important control variable of cell division, but not the sole one. (pnas.org)
  • Focusing on Escherichia coli in steady growth, we quantify cell division control using a stochastic model, by inferring the division rate as a function of the observable parameters from large empirical datasets of dividing cells. (pnas.org)
  • Cell division control couples growth and division, influencing most aspects of cellular physiology ( 1 ). (pnas.org)
  • Current high-throughput microfluidic techniques enable experiments measuring the attributes of many cells ( 9 ) opening up the possibility of testing quantitative models of cell division control. (pnas.org)
  • centrosomes
  • When a cell is not dividing, the chromatin is enclosed within a clearly defined nuclear envelope, one or more nucleoli are visible within the nucleus, and two centrosomes (each containing two centrioles) lie adjacent to one another outside the nuclear envelope. (cliffsnotes.com)
  • cancer
  • What is a cancer cell? (abpischools.org.uk)
  • Investigate one of the more recent forms of cancer therapy and produce a poster explaining how the cancer forms in the body and how the therapy you have chosen prevents the growth and spread of the tumour and/or kills the cancer cells. (abpischools.org.uk)
  • organism
  • For simple unicellular microorganisms such as the amoeba , one cell division is equivalent to reproduction - an entire new organism is created. (wikipedia.org)
  • Even in the simple model organism E. coli , a fully quantitative characterization of how cell division time and size are determined is lacking ( 6 ), with most attempts dating back to the 1960s ( 2 , 7 , 8 ). (pnas.org)
