Prokaryotic cells are …
There are several available tools for gene editing, all of which use enzymes that act on DNA called nucleases. The different editing tools act on a similar basic principle: the enzyme is directed to a specific target site in the genome by either a guide sequence or by specific DNA binding domains within the nuclease itself.

Neural stem cells from the SGZ are called Type I cells and can generate proliferating IPCs, called Type 2 cells, similar to the type B cells of the SVZ. Intermediate progenitor cells give rise to neuroblasts (Type 3 cells) (Seri et al., 2004; Sugiyama et al., 2013). The mechanism of mammalian, and in particular human, neurogenesis remains unclear.
Of course, there are many cases in which cells must respond quickly to changing environmental conditions. In these situations, the regulatory control point may come well after transcription.

They take their name from the "B" in "bone marrow." Like the T cells, there are many different types of B cells that match particular germs. B cells are activated by T helper cells: T helper cells send signals to B cells that match the same germs as they do. This stimulates the B cells to make copies of themselves and turn into plasma cells.
