Abstract

Defining the basis of the selective cell vulnerability of human motor neurons (hMNs) represents a crucial step in revealing the pathogenesis of amyotrophic lateral sclerosis (ALS). Tissue culture models offer an ideal system for identification of the hMN-specific features at the single cell level. Purified hMNs and astrocytes can today be isolated from the anterior horn of the human embryonic spinal cord. Cultures can be studied at the single cell level using cDNA/mRNA amplification techniques. The effects of molecules affecting hMN survival, neurite extension, and metabolism can be tested in vitro and the expression of selective genes assayed using DNA microarray technology. Crucial information of immediate, clinical application for the treatment of patients affected by ALS can be derived after testing the efficacy of candidate pharmaceutical molecules using in vitro cells models. Adult nervous tissue or progenitor cells derived from different regions of the nervous system may be used as an alternative source of human neuronal cells. HMNs in culture, combined with the application of adequate technology, can contribute greatly to identifying the primitive critical events responsible for the cell degeneration observed in ALS, bypassing the intrinsic limitations of the non-human models of the disease.
