Sentences with phrase «asymmetric cell»
The phrase "asymmetric cell" means that the cell is not the same on both sides. It has a different shape, structure, or function on one side compared to the other. Full definition

She also investigates how asymmetric cell division impacts on the cellular potential to give rise to multiple lineages in vivo.
Li and her colleagues also determined that the association of aggregates with mitochondria gradually declines in the mother budding yeast cells with advanced replicative age, likely contributing to their diminished ability to rejuvenate through asymmetric cell division.
Symmetry breaking transitions on curved surfaces are found in a wide range of dissipative systems, ranging from asymmetric cell divisions to structure formation in thin films.
The group's results show that MTs are responsible for elongation of the zygote along the top - bottom axis, whereas F - actin plays a role in moving the nucleus towards the top part of the zygote, to make it ready for asymmetric cell division.
«We were able to show by live cell imaging that polarization of the cell occurs after fertilization of the egg cell, and both MTs and F - actin play a role in inducing asymmetric cell division to form the plant's body axis,» says Ueda.
Through live cell imaging, the group was able to visualize how fertilized egg cells in plants undergo asymmetric cell division, which is responsible for determining the plant's body axis.

Polarized endosome dynamics by spindle asymmetry during asymmetric cell division.
This is the first time to visualize the real time event of asymmetric cell division, and we were able to see other events such as cell elongation of the zygote and migration of the nucleus.»
This asymmetric cell division leads to small and large cells on the top and bottom part of the embryo, respectively.
The current study builds upon previous research, published by the Li lab in 2011 in Cell, that revealed that most aggregates of unfolded proteins are retained by the mother yeast cell during the asymmetric cell division that characterizes this organism as well as stem cells.
An asymmetric cell division in non-stem cells can instead result in two daughter cells with very different fates, such as one large cell that reinitiates cell division prematurely and a much smaller cell that either grows very slowly or dies.
«I'd like to see what's different in asymmetric cell division,» he says.
Not only did the group succeed in visualizing the real time events of zygote polarization and asymmetric cell division, they were able to quantify the dynamic patterns of the cytoskeleton (i.e. formation of the ring structure and longitudinal array of MTs and F - actin, respectively).
The group succeeded in visualizing for the first time, how the cytoskeleton of plant egg cells is disassembled after fertilization and then reorganized to create a polarity in the cell that eventually leads to asymmetric cell division.
«Although polarization and asymmetric cell division of zygotes to form the body axis is a common phenomena found in algae, mosses, and flowering plants, the origin of cell polarity and how asymmetric cell division occurs have remained a mystery up to now,» says Dr. Minako Ueda, a lecturer at ITbM, Nagoya University and a leader of this research.
In order to investigate their specific roles, they used inhibitors of each protein to see their effect on zygote polarization and asymmetric cell division.
