Microspores and pollen grains are produced from pollen mother cells
(Microsporocytes), PMCs within loculus anthers of the flower.
Development of the quadripolar meiotic cytoskeleton in spore mother cells
of the moss Funaria hygrometrica.
If a mother cell
divides symmetrically, many scientists theorized that the offspring inherit cellular components equally ravaged by the experiences of previous generations.
About three-quarters of the way through the life of each mother cell
, colored colonies appeared, signaling the presence of genes gone awry.
This multilayered tapetum does not develop plasmodesmata at the pollen mother cell
stage but the cell walls break down successively in the layers of tapetal cells, discharging protoplasm into the locule, where it is not enclosed by a perispore membrane [ILLUSTRATION FOR FIGURES 19-23, 34, 35 OMITTED].
These cells are closely arranged in the entire pollen chamber and further develop into microspore mother cell
The researchers point out that two daughter cells arise from a single sensory organ precursor mother cell
in the fly peripheral nervous system, and that among the daughter cells, Notch is activated in one and not in the other.
Multicellularity might be achieved by allowing the mother cell
to retain control over the daughter cell it creates.
It is therefore possible to produce approximately one ton of biomass from a tube of only one milliliter of mother cells
within one week, the entire process is automated and supervised by monitoring software and a hundred or so sensors to ensure quality, traceability and reproducibility.
Options with stem cell therapies include transplantation of mother cells
, orthomolecular and hyperbaric medicine.
