	Theodor Schwann (1810-1882)
		Theodor Schwann, a German cytologist and physiologist, was born in Neuss, Germany on December 7, 1810.
		Schwann became professor at the Belgium Universities of Louvain, in 1838, and Liège, in 1848.
		Schwann coined the term "metabolism" to describe the chemical changes that take place in living tissue and formulated the basic principles of embryology by observing that an egg is a single cell that will eventually develop into a complete organism.

	Schwann cell culture
		There are numerous reasons why culturing adult Schwann cells is essential: to study the membrane properties of Schwann cells and axon-Schwann cell communication and how these might be altered in neuropathic conditions; to use Schwann cells for the repair of lesioned peripheral nerve; or to exploit their potential for regeneration in CNS lesions.
		The use of Schwann cells in surgical repair of lesioned peripheral nerves or CNS lesions also necessitates the use of adult cells derived from the recipient, since allogeneic Schwann cells are subject to rejection(2,3).
		Unfortunately, Schwann cells are difficult to isolate from adult mammalian peripheral nerves because of the abundance of connective tissue and the highly differentiated state of the cells, particularly those involved in the formation of myelin.

	Schwann Cells
		Schwann cells are the supporting cells of the PNS.
		Like oligodendrocytes schwann cells wrap themselves around nerve axons, but the difference is that a single schwann cell makes up a single segment of an axon's myelin sheath.
		In the above picture, the dark circles are schwann cells surrounding PNS axons creating a protective layer known as the myelin sheath.

	Cell Theory
		This nucleus (or areola as he called it) of the cell, was not confined to the epidermis, being also found, in the pubescence of the surface and in the parenchyma or internal cells of the tissue.
		This nucleus of the cell was not confined to only orchids, but was equally manifest in many other monocotyledonous families and in the epidermis of dicotyledonous plants, and even in the early stages of development of the pollen.
		Brown descibed the cell nucleus in cells of the orchid.

	Schwann cell - Psychology Wiki - a Wikia wiki
		Non-myelinating Schwann cells are involved in maintenance of axons and are crucial for neuronal survival.
		Schwann cells are the peripheral nervous system's analogues of the central nervous system oligodendrocytes.
		The gaps between the Schwann cell covered segments are the Nodes of Ranvier, important sites of ionic and other exchanges of the axon with the extracellular liquid.

		Particularly was this found to be the case with embryonic tissues, and the study of these soon convinced Schwann that his original surmise had been correct, and that all animal tissues are in their incipiency composed of particles not unlike the ultimate particles of vegetables in short, of what the botanists termed cells.
		Schwann believed, however, that in the mature cell the nucleus ceased to be functional and disappeared.
		And when Schwann put forward the explicit claim that "there is one universal principle of development for the elementary parts, of organisms, however different, and this principle is the formation of cells," he enunciated a doctrine which was for all practical purposes absolutely new and opened up a novel field for the microscopist to enter.

	Body Part - Schwann cell
		Schwann cells are part of the peripheral nervous system (PNS) that lies outside of the central nervous system (CNS).
		Schwann cells perform the same role in the PNS as the oligodendrocytes do in the CNS.
		Schwann cells are essential to the process of peripheral nerve fiber regeneration.

	Miami Project \| Exploring the Nervous System, Cell by Cell
		Oligodendrocytes and Schwann cells are both classified as glia (to early anatomists, the "glue" that held the nervous system together).
		The Schwann cells did not stop functioning completely; instead of forming myelin, they were non-myelinating, a state which is also commonly seen in the PNS.
		Other important cells in the nervous system are called microglia, which, in spite of their name, are derived from cells of the immune system rather than the glia of the nervous system.

		On October 22, 2002, a biopsy was taken on the trial's third patient, a 64-year-old woman with the primary progressive form of MS who received a Schwann cell transplant in April.
		Schwann cells are the cells that produce myelin in the peripheral nervous system (in contrast to oligodendrocytes, the myelinating cells in the central nervous system).
		This trial uses autologous transplantation, meaning the cells are harvested from the patients themselves, in this case from the ankle.
