Definitions

1. Schwann cells were plated onto the neurons and maintained in neurobasal medium with supplements until the Schwann cells populate the axons (about 7-10 days).
2. Schwann cells (S) are scattered among the nerve fibers, and several flattened fibroblast (Fb) nuclei are evident in the perineurium.
3. Schwann cells are absolutely essential for the maintenance of healthy axons.
4. Schwann cells are of neural crest origin.
5. Schwann cells are the peripheral nervous system's analogues of the central nervous system oligodendrocytes.

Neural Stem Cells

1. For example, astroglia, oligodendrocytes, microglia cells, Schwann cells, fibroblast, neuroblast, neural stem cells and mature neurons.

Vestibular Schwannoma

1. It is from Schwann cells in the vestibular nerve that an acoustic neuroma, also known as a vestibular schwannoma, arises.

Adrenocortical Cells

1. Characteristic findings are lamellar cytoplasmic inclusions in the brain macrophages, Schwann cells, Leydig cells, and adrenocortical cells.

Plasma Membranes

1. Schwann cells contain a lipid substance called myelin in their plasma membranes.

Supporting Schwann Cells

1. The axons of some vertebrate neurons have a fatty myelin sheath formed by supporting Schwann cells.
2. Peripheral nervous system - Peripheral nerve axons and their supporting Schwann cells are held together by connective tissue forming nerve fibers.

Adjacent Schwann Cells

1. Myelin also contains about 20 % of proteins whose prime role is to mediate adhesion between adjacent Schwann cells.
2. These nodes are interuptions of the myelin sheath due to gaps between adjacent Schwann cells.

Specific

1. The autoimmune response is specific to islet cells, but in some cases thyroid cells and Schwann cells are also casualties (43, 44, 45).
2. In addition, he said, the system they are using in the mice is not specific enough to only infect the Schwann cells.

Maintenance

1. Non-myelinating Schwann cells are involved in maintenance of axons and are crucial for neuronal survival.

Layers

1. Schwann cells wrap themselves many times around the axon of a neuron creating multiple layers of membrane between the axon and surrounding tissues.

Insulation

1. Unlike oligodendrocytes, myelinating Schwann cells provide insulation to only one axon (see image).

Cell Types

1. The neural crest gives rise to a variety of cell types including Schwann cells of the peripheral nervous system.

Nerve

1. The cells surrounding a nerve are called Schwann cells.
2. This is a benign tumour which arises from schwann cells which cover the nerve that goes to the ear.
3. Cultured Schwann cells contained many large membrane-bound vacuoles, presumably lysosomes, resembling those present in the biopsied nerve.

Nerve Fibers

1. Schwann cells produce the fatty insulin called myelin that surrounds some nerve fibers.
2. These type C nerve fibers are usually found running in long, deep longitudinal depressions in Schwann cells (Fig-4).

Special Cells

1. Protection is also given by Schwann cells, special cells within the nervous system that wrap around both myelinated and unmyelinated axons.
2. In vertebrates, special cells called Schwann cells wrap around the axons and serve as isolating tape of sorts.

Chromaffin Cells

1. It gives rise to dorsal root ganglia, chromaffin cells, Schwann cells, and other specialized cell types.

Schwannoma

1. Schwannoma is a benign, encapsulated tumor that is derived from Schwann cells.

Schwannomas

1. Schwannomas - Schwannomas are benign tumors that arise from cells called Schwann cells that cover the cranial nerves.
2. Schwannomas are also benign tumors, specific to the myelin-producing cells (Schwann cells) for the acoustic, or hearing, nerve.
3. Schwannomas are benign tumors that begin in Schwann cells, which produce the myelin that protects the acoustic nerve.

Aldose Reductase

1. Aldose reductase is also present in the lens, retina, Schwann cells of peripheral nerves, placenta and red blood cells.
2. Aldose reductase transforms the sugar into sorbitol, which in turn draws water into the Schwann cells, causing them to swell.

Ranvier

1. Node of Ranvier (NODE OF rahn-VEEAY): Small area between Schwann cells on an axon that is unmyelinated or uncovered.
2. The gap between Schwann cells is known as the node of Ranvier, and serves as points along the neuron for generating a signal.
3. The gaps between adjacent Schwann cells are called nodes of Ranvier (see above).

Endoneurium

1. The eosinophilic staining between nerve fibers is due to the cytoplasm of the Schwann cells and cells of the endoneurium.
2. There are not the endoneurium and schwann cells in the central nervous system.

Regrowth

1. Paino CL, Fernandez-Valle C, Bates ML, Bunge MB. Regrowth of axons in lesioned adult rat spinal cord: promotion by implants of cultured Schwann cells.

Form

1. In the PNS, special cells known as Schwann cells form the myelin sheath.
2. Myelinating Schwann cells wrap around axons of motor and sensory neurons to form the myelin sheath.

Neurons

1. The loss of neurofibromin, which is expressed in neurons, Schwann cells, the adrenal medulla, and white blood cells, may contribute to tumor progression.

Fibroblasts

1. In addition to fibroblasts, the endoneurium also contains blood capillaries necessary to supply nutrients to the Schwann cells.
2. They comprise Schwann cells, nerve fibers, fibroblasts, vascular elements, mast cells, and myxoid matrix.

Cells

1. Other cells that may be present include one or more of oligodendrocytes, astrocytes, ependymal cells, microglial cells or Schwann cells.
2. Other cells from the neural crest travel further to form the neuroglia (Schwann cells or neurolemmocytes) of all the peripheral nerves.
3. Schwann cells that form neural sheaths of some nerve fibers and of peripheral nerves form from neural crest cells and cells from the mantle.

Nerves

1. These PNS glia include Schwann cells in nerves and satellite cells in ganglia.
2. These PNS glia include Schwann cells in nerves and satellite glial cells in ganglia.

Sheath

1. The sheath is formed by the cell membranes of glial cells (SCHWANN CELLS in the peripheral and OLIGODENDROGLIA in the central nervous system).
2. The nuclei found juxtaposed to the sheath are Schwann cells.

Cns

1. The Schwann cells assure that the electric charge goes where the central nervous system (CNS) intends it to go.

Pns

1. In the CNS, myelin is produced by oligodendroglial cells and in the PNS by Schwann cells.
2. In the PNS, glial cells known as Schwann cells promote repair.
3. Connexin32 mutations cause loss of function in Schwann cells and oligodendrocytes leading to PNS and CNS myelination defects.

Axon

1. Many Schwann cells grow along the axon and act as a kind of insulation for the nerve cell.
2. After axonal injury, Schwann cells regress to an earlier developmental state to encourage regrowth of the axon.
3. Myelin is made of specials cells called Schwann Cells that forms an insulated sheath, or wrapping around he axon.

Axons

1. Finally, many bundles are bound together (along with blood vessels to nourish the axons and Schwann cells) by even tougher connective tissue to form a nerve.
2. Myelination of axons also occurs within the brain and spinal cord but utilizes cells different from Schwann cells.
3. Paclitaxel induced neuropathy is probably due to dysfunctional microtubules in dorsal root ganglia, axons and Schwann cells [ 10, 11].

Peripheral Nervous System

1. Consequently, the fibers are covered with myelin produced by oligodendrocytes rather than the Schwann cells of the peripheral nervous system.
2. Exceptions include the oligodendrocytes which myelinate neural axons (a role performed by Schwann cells in the peripheral nervous system).
3. In the peripheral nervous system, where the problems associated with diabetic neuropathy originate, Schwann cells perform this function.

Oligodendrocytes

1. Myelin is produced by specialized cells: oligodendrocytes in the central nervous system, and Schwann cells in the peripheral nervous system.
2. Oligodendrocytes (in the CNS) and Schwann cells (in the PNS) are glia that form myelin sheaths around the axons of vertebrate neurons.
3. The sheaths are formed by glial cells: oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system.

Myelin Sheath

1. Outside the myelin sheath is a cellular layer called the neurilemma or sheath of Schwann cells.
2. Some axons are wrapped in a myelin sheath formed from the plasma membranes of specialized glial cells known as Schwann Cells.
3. The myelin sheath in peripheral nerves consists of Schwann cells wrapped in many layers around the axon fibers.

Myelin

1. The axons of the peripheral nerves are enclosed in a fatty (myelin) sheath formed from specialized cells called Schwann cells.
2. This signal directs Schwann cells, the nervous system's cellular architects, to build elaborate sheaths of myelin around the axons of nerve cells.
3. Myelinated - nerves axons which are completely wrapped in a sheath of myelin by schwann cells.

Schwann Cells

1. In the PNS, supporting cells called Schwann cells: form myelin sheaths; in the CNS, supporting cells called oligodendrocytes produce the myelin sheaths.
2. In the PNS, neurons are supported by Schwann cells and satellite cells (which form around the cell body to protect and cushion it).
3. Schwann Cells - are cells of the Peripheral Nervous System (PNS) that make and maintain its Myelin as well as the formation of the Neurilemma.
