In the adult body, neural stem cells are responsible for producing new neurons. These stem cells are mainly found in two regions of the brain: the hippocampus, which is involved in learning and memory, and the subventricular zone, which contributes to the generation of olfactory neurons.
The three types of stem cells in adults are hematopoietic stem cells (found in bone marrow and produce blood cells), mesenchymal stem cells (found in various tissues like bone marrow and fat, can differentiate into bone, cartilage, and fat cells), and neural stem cells (found in the brain and spinal cord, can differentiate into neurons and supporting cells).

Adult stem cells
Humans are capable of generating new neurons only upto the age of 20 or so. Till then, there are very few neuron stem cells that divide to produce neurons. Others are all arrested. ie. they cannot undergo cell division. Beyond the age of 20, there are practically no neuron stem cells. They are all locked.
a stem cell line is a group of stem cells that has the ability to produce one specific type of cell. for example, one stem cell line could have the ability to produce a kidney, while another line could produce a liver.
Pluripotent stem cells.
Adult stem cells
Basal cells are stem cells in the olfactory epithelium that can regenerate olfactory sensory neurons. They differentiate into new olfactory sensory neurons to replace damaged or dying cells, helping maintain the olfactory sensory system's ability to detect and transmit odor information to the brain.
Only adult stem cells produce progenitor cells because they multiply though the process of cell division and therefore produce progenitor cells.
