Amyotrophic Lateral Sclerosis (ALS/Lou Gerhig’s Disease)

See Table of Stains appropriate for ALS



Also referred to as Lou Gerhig’s Disease, Amyotrophic Lateral Sclerosis (ALS) is a progressive, neurodegenerative disease affecting nerve cells in the brain and spinal cord. Motor neurons reach from the brain to the spinal cord, and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death, resulting in a loss of the brain’s ability to initiate and control muscle movement.

Rodent Spinal Cords:  Spinal cord tissue of animal models is commonly used in ALS research. There are several approaches NSA employs in processing spinal cord tissue.

40 Rodent Cords
Transverse/CoronalUp to 40 spinal cords are co-embedded and appear
on each MultiCord® slide section.

8 Rodent Cords
Transverse/LongitudinalUp to 8 spinal cords are co-embedded and appear
on  each MultiCord® slide section.

Human Tissue:  NSA processes large format sections, as seen below, providing a unique opportunity to assess large contiguous cross-sections of tissue. NSA also processes multiple smaller samples from one or more spinal cords using MultiCord® Technology. The standard NSA practice of encasing the spinal cord tissue in gelatin provides a significant aid in the handling of tissue sections resulting in an improved final product.

Ubiquitin in SOD1 Mouse Model

Ubiquitin can help identify abnormal accumulations
of this protein inside the cells, indicating a disease process.
