|March 18, 2017
Summary
Cell therapy offers promise for spinal cord injury (SCI) repair by replacing cells and providing support. However, combinatorial strategies are likely needed for effective treatment due to SCI
Area of Science:
- Neuroscience
- Regenerative Medicine
- Cell Therapy
Background:
- Spinal cord injury (SCI) results in paralysis due to failed regeneration and cell loss.
- Current treatments for SCI lack regenerative capabilities.
- Stem cells offer multi-targeted benefits, making cell therapy a promising approach.
Purpose of the Study:
- To review current cell therapies investigated for spinal cord injury.
- To discuss mechanisms of action for different cell types.
- To highlight the need for combinatorial approaches in SCI treatment.
Main Methods:
- Review of preclinical and clinical studies on cell therapies for SCI.
- Analysis of cell replacement, scaffolding, trophic support, and immune modulation mechanisms.
- Discussion of various cell types including stem cells and progenitor cells.
Main Results:
- Single cell therapies show modest benefits in preclinical and clinical studies.
- Different cell types target unique aspects of SCI pathology.
- Combinatorial cell therapy approaches are increasingly recognized as necessary.
Conclusions:
- While promising, single cell therapies have limited efficacy for SCI.
- Future research should focus on combinatorial strategies and addressing cost-effectiveness.
- Standardized protocols and regulatory guidelines are crucial for clinical trials.

01:21Stem Cell Therapy for Tissue Regeneration
4.8K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

01:15Neurogenesis and Regeneration of Nervous Tissue
1.9K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

01:54The Spinal Cord
32.6K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
