This type of cell division is called an asymmetric cell division and is of fundamental importance to brain development because it allows the brain to get bigger by repeatedly generating more cells (the daughter that is the progenitor does this) while also making some cells that construct the neural circuits that underlie animal behaviour (the daughter that is the neuron does this by connecting and communicating to other neurons).
In addition, the analysis showed that asymmetric cell division and quiescence of stem cells increased in older mice.
A knockdown of ASPM results in alterations in cleavage plane orientation, leading to a premature switch from symmetric to asymmetric cell division (Fish et al., 2006).
As we mentioned before, SCs may divide by either symmetric cell division (SCD) or asymmetric cell division (ACD).
Their topics include mitochondrial and peroxisomal divisions, mechanisms of organelle inheritance in dividing plant cells, the regulation of plant cell expansion: auxin-induced turgor-driven cell elongation, asymmetric cell division in the zygote of flowering plants: the continuing polarized event of embryo sac development, and death and rebirth: programmed cell death during plant sexual reproduction.
Mikolaj Ogrodnik (Graduate student, Newcastle University, United Kingdom) has been studying asymmetric cell division (where cells divide without both sides being the same) as a means of rejuvenation.
Root hair development involves asymmetric cell division in Brachypodium distachyon and symmetric division in Oryza sativa.
Cancer stem cells (CSCs) are cells that are defined by their ability to self-renew and undergo asymmetric cell division, proliferation, and differentiation.
One of the cardinal principles of the CSC hypothesis is that (only) CSCs have the capacity to undergo symmetric cell division (for self-renewal) as well as asymmetric cell division (to give rise to differentiated progeny).
Interdependence of filamentous actin and microtubules for asymmetric cell division. Biol.
The differential activation of signalling leads to two different kinds of cells which arise from the same mother cell, a reason why the researchers used the fruit flies sensory organ precursor cell division as a model to understand how Notch signalling is activated during asymmetric cell division.
"This tells us that the TMM protein probably receives signals that orient the position of asymmetric cell division," Sack said.
