What type of cells line the ventricles of the brain? ependymal cells neurons epithelial cells astrocytes?

Ependyma cells. These cells that make up the neuroectodermal padding is responsible for the production of cerebral spinal fluid. The cells are one type of neuroglia cells of the central nervous system. The lining of ependyma cells of the brain also plays a role in neuroregeneration.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
