Stem Cells In Thailand And The Proliferation Of Alzheimer Disease
Alzheimer’s disease is among the most complex and least treatable neurodegenerative diseases found in millions of people across the globe. Alzheimer’s results from the destruction of neurons and bridges in the brain causing gradual memory loss, cognitive changes and behavioral changes. Thus more conventional treatments can only ever offer some symptomatic relief but those being treated also accepted that in reality any of the traditional therapies never actually prevent the progression of disease. Recent progress on stem cell technology, especially umbilical cord-derived mesenchymal stem cells (UC-MSCs), reveals a new avenue for research and treatment in this debilitate disease.
And while those stats are pretty shocking, stem cell science is a new tool in the fight against Alzheimer’s in Thailand. Researchers and clinicians are currently exploring the optimal qualities of reprogrammed stem cells, not only as in vitro disease modeling instruments but also closely related novel therapeutic agents potentially therapeutically useful for local restoration by local regenerative replacement (of lost neural function) through repair/relief of inflammation.
Stem Cells And Their Role In The Treatment Of Alzheimer Disease
Stem Cells have the unique ability to differentiate into all cells of the body, including neurons–the brain cells that die first in Alzheimer’s. This unique characteristic makes them appropriate for the generation of regenerative therapeutics to repopulate or repair neurons which are lost during disease progression.
Researchers hope to mobilize neural repair by grafting stem cells into targeted locations of the brain in an effort to reinnervate diseased circuitry and restore or protect cognition in Alzheimer´s sufferers.
Key Therapeutic Functions:
● Neurogenesis (the process of generating new neurons): Stem cells could facilitate the generation of neurons, especially in the area of the brain that relates to memory and learning – hippocampus. This can help counteract the neuronal atrophy caused by Alzheimer and stimulate brainplasticity.
● Cell Replacement Therapy — Stem cell therapy emphasizes the replacement of deteriorating or malfunctioning neurons with totally new cells so that brain function can be maximized longer, limiting cognitive decline.
Types of stem cells used in models for the study of disease, such as Alzheimer and other dementias
Many stem cells are investigated for their potential applications in Alzheimer’s disease, which can be divided into homogeneous properties and usage types:
Mesenchymal Stem Cells (MSCs) Derived From Umbilical Cords —UC-MSCs are derived from the Wharton’s jelly of umbilical cords. They are non-controversial, able to be easily sourced and have potent anti-inflammatory and neuroprotective properties. Such as, this cell have the best safety and part of therapeutic profile so this cell is one of well-used clinical use cells in regenerative medicine in Thailand.
Induced Pluripotent Stem Cells iPSCs are adult cells that have been easily reprogrammed back into a pluripotent state, where they can become almost any cell type including neurons.
Neural stem cells (NSCs): NSCs are isolated from the brain and spinal cord, they tend to produce nervous system cells. They show promise for the selective rehabilitation of neurons in degenerative diseases.
Embryonic Stem Cells (ESCs) — These are pluripotent they can differentiate to any cell.
Mechanistic Basis of Stem Cells for Alzheimers Disease
This has then proposed multiple therapeutic mechanisms for stem cells that may benefit Alzheimer patients:
Neuroprotection
These stem cells express a number of growth factors and signalling molecules which help to protect the remaining neurons that are already damaged. Thanks to this neuroprotection, the development of the disease is slower.
Regeneration of Brain Tissue
Stem cells can repair wounded areas of the brain including, in this case, portions involved with memory, attention and decision-making (i.e. the hippocampus and cortex). Through this process, it may also boost cognitive ability.
Inflammation Reduction
Inflammation is a recognized contributor to disease progression in Alzheimer’s. In addition, some stem cells like mesenchymal stem cell are reported to have immunomodulatory role and neuroprotection through reduction of harmful immune-mediated inflammatory responses (Guilloton et al., 2019).
Delivery of Therapeutic Agents
Indeed, we can engineer stem cells to carry drugs, enzymes or even genetic material and release them into dysfunctional parts of the brain so they can provide targeted therapy that could be more effective.
Conclusion
In conclusion, stem cell therapy—especially with umbilical cord-derived mesenchymal stem cells (UC-MSCs), is a novel and promising approach for the treatment of Alzheimer. Because stem cells target the underlying mechanisms of neural degeneration, repair, and inflammation (rather than just symptoms), they represent an exciting new therapeutic direction for patients with neurodegenerative diseases.
Thailand on the other hand offers much more than advanced therapies in a well-regulated and ethical medical system carried out by experienced professionals employing sophisticated technologies. Considering the above, stem cells should be included in the future of treating Alzheimer, something that is a very positive sign for caregivers and families who have had their lives considerably altered by this disease.
