21. In particular, glial cells demonstrate an interaction with the growth cones of pioneer axons. 22. These PNS glia include Schwann cells in nerves and satellite glial cells in ganglia. 23. Gliotransmission can also occur between two types of glial cells : astrocytes and microglia. 24. Same with rods and cones and neurons and glial cells . 25. Microglial cells are of the most prominent types of glial cells in the brain. 26. Calcium waves are supported by glial cells , which help maintain and modulate neuronal metabolism. 27. Because of this, glial glutamate receptors are thought to be vital for glial cell development. 28. Despite such problems, researchers are hopeful about the newest neurotrophic factor, glial cell -derived neurotrophic factor. 29. As more tissue dies, the glial cells release chemokines and cytokines ( pro-inflammatory compounds ). 30. He studies the development and function of glial cells in the mammalian central nervous system.
