Abstract
Spinal cord injury (SCI) remains one of the most devastating conditions among neurological diseases due to its pathologic consequences. It is estimated that this lesion affects about 330,000 European people as trauma from an incident (for example, a motor vehicle accident or a sport injury), or by violence such as gunshot wound, or because of medical treatments or diseases such as polio and split spine (http://www.eurostemcell.org). SCI effects can be classified as âprimary injuryâ including the interruption of ascending and descending pathways due to a contusive, compressive, or stretch injury of the spinal cord, and as âsecondary injuryâ that is related to posttraumatic degeneration of the tissue and leading to severe motor or sensory disabilities, often accompanied by paralysis of the arms or legs.

Spinal cord anatomy
The central nervous system, formed by brain and spinal cord, is the center in charge of reception, elaboration, and information transmission. The spinal cord comprises a bundle of neurons and has its place in the spinal canal that protects it. In humans, it has a cylindrical form, with 8â10 mm of medium diameter, starts at the base of the skull, but does not occupy the vertebral canal for his entire length, ending in the firsts lumbar vertebras. The spinal column and the spinal cord are divided into five regions: cervical, thoracic, lumbar, sacral, and coccyx (Fig. 1.1). From the spinal cord start the peripheral nerves, responsible for motor and sensory capabilities of the entire body. An external stimulus detected, for example, by the skin, is converted into chemical signals that are transported along the axons to the dorsal side of spinal cord and finally to the brain. In the brain, they are elaborated and the responsive motor signal goes back to the ventral side of the spinal cord and to the region that perceived the stimulus.
Three membranes, called meninges, of protective tissue cover the entire spinal cord. The external membrane has been named dura mater because of this strength, the intermediate one is the delicate arachnoid, which is thin and with web-like filaments, and the inner membrane is called pia mater. Between arachnoid and pia mater, there is a space filled with cerebrospinal liquid, and this gap contains arteries that supply blood to the spinal tissue: in case of trauma, there will be hemorrhaging.
Internal organization
The spinal cord is composed of two different types of tissue: the inner part appears grayish and is called gray matter; the outer instead is white and is called white matter (Fig. 1.2). White matter is subdivided into columns, each one containing neurons related to specific functions. The lateral columns include axons that travel from the cerebral cortex to contact spinal motor neurons. In the dorsal zone, sensibility information are carried up way to the brain. The ventral columns carry both ascending information about pain and temperature and descending motor information. Gray matter is divided into dorsal and ventral horns. The dorsal ones are for skin stimulus reception; the ventral ones receive proprioceptive fibers, and the middle part receives sensorial inputs from muscles and viscera. The muscle's motor activity is the result of the cooperation that takes place between different groups of neurons put in series: if one of them is damaged, the information circuit would be broken and the movement results impeded.

Spinal cord injuries
Spinal cord injury (SCI) is a condition that implies a loss of motor abilities and results to be one of the first causes of noncongenic disability in the world, with an annual incidence between 40 and 80 cases per million people. About two and a half millions of the people worldwide are affected by SCI [2â4]. Most of them are male (82% in the United States, 72.7% in India), and the mean age is 33 years, with a tendency to rise. The causes vary in the world differently from country to country and are mostly related to vehicular accidents, falls, violence, or sport activities. In addition, t...
