Living organisms are extremely complex functional systems. At present, there are many in vivo models of spinal cord injury (SCI) that allow the modeling of any type of central nervous system (CNS) injury, however, with some disadvantages. The production of injury models can be a highly invasive and time‐consuming process and requires high technical requirements, and costly financial issues should also be taken into account. Of course, a large number of animals have been used to obtain the relevant data of statistical significance. All of these aspects can be reduced by carrying out experiments in in vitro conditions. The primary advantage of in vitro method is that it simplifies the system under study. There are two major groups of in vitro model in use: cell culture and organotypic slice (OTS) culture. OTS is an intermediate system of the screening of in vitro cell culture and animal models and represents the in vitro system preserving the basic tissue architecture that able to closely mimic the cellular and physiological characteristics in vivo. In vitro models are the preferred methods for the study of acute or subacute pathophysiology after a trauma stimulus, enabling precise control on the extracellular environment, easy and repeatable access to the cells.
