What is an intermediate stem cell?
Intermediate progenitor cells (IPCs) are a type of progenitor cell in the developing cerebral cortex. In mammals, neural stem cells are the primary progenitors during embryogenesis whereas intermediate progenitor cells are the secondary progenitors.
Can stem cells divide for long periods of time?
Stem cells are unique because they have three distinct properties: They can divide and renew (proliferate) themselves over long periods of time. They are not specialised (unlike every other cell in the body) They can give rise to these others specialised cells (differentiate)
What happens to one of the stem cells after division?
Usually, when a stem cell divides into two, one daughter cell goes on to make a more specialized type of cell, or even gives rise to several different cell types. These are known as embryonic stem cells or ES cells, and they have the potential to produce all the cell types in the human body.
What phase does the cell do most of its growing?
interphase
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Where is the subventricular zone?
lateral ventricle
The subventricular zone (SVZ) is one of two regions where neurogenesis persists in the postnatal brain. The SVZ, located along the lateral ventricle, is the largest neurogenic zone in the brain that contains multiple cell populations including astrocyte-like cells and neuroblasts.
What are pluripotent stem cells?
Pluripotent stem cells are cells that have the capacity to self-renew by dividing and to develop into the three primary germ cell layers of the early embryo and therefore into all cells of the adult body, but not extra-embryonic tissues such as the placenta.
What is G not face?
The G0 phase (referred to the G zero phase) or resting phase is a period in the cell cycle in which cells exist in a quiescent state. Multinucleated muscle cells that do not undergo cytokinesis are also often considered to be in the G0 stage.
What cells divide the fastest?
Basal cells divide faster than needed to replenish the cells being shed, and with each division both of the two newly formed cells will often retain the capacity to divide, leading to an increased number of dividing cells.
What type of stem cell is better?
Embryonic stem cells are pluripotent, meaning they can give rise to every cell type in the fully formed body, but not the placenta and umbilical cord. These cells are incredibly valuable because they provide a renewable resource for studying normal development and disease, and for testing drugs and other therapies.
