mother cells (Microsporocytes), were also detectable (Fig 1B).
less functional, proteins stay in the
mother cell. (31) Although these SIR2-dependent events are also thought to contribute to the processes that determine cellular lifespan, the major determinant in yeast seems to be transcriptional repression of E-pro.
Establishment of plastid-based quadripolarity in spore
mother cells of the moss Funaria hygrometrica.
At this point the tube nucleus disintegrates and one sperm nucleus fertilizes the egg nucleus and the other sperm nucleus fertilizes the endosperm
mother cell (Fig.
The end cells produced by the animal
mother cell might have been in the form of eggs while those originated from the other
mother cells might have been spores, seeds, or some other form.
The key is the growth of a stem cell or "
mother cell", with the ability to develop into different kinds of tissue, cloned from the patient's own cells.
A: A stem cell is a '
mother cell' with the ability to develop into different kinds of tissue.
Cell B becomes the
mother cell of the peripheral cells of the embryo's head.
It has been assumed that during mitosis the
mother cell expels its cytokeratin in a degraded form to the cellular environment.
The
mother cell that leads to both the macrophage and neutrophil is called a "bipotent precursor" since it has the potential to form either cell type depending on the specific circumstances it finds itself in.
