EPS and iPS Cells in Disease Research

3.2K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

iPS Cell Differentiation

2.9K
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.

Induced Pluripotent Stem Cells

26.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Induced Pluripotent Stem Cells

5.1K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic...

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Area of Science:

  • Neuroscience
  • Regenerative Medicine
  • Stem Cell Biology

Background:

  • Parkinson's disease (PD) involves dopamine neuron loss, leading to motor and non-motor symptoms.
  • Current treatments like dopamine replacement and deep brain stimulation (DBS) offer symptomatic relief but do not halt disease progression.

Purpose of the Study:

  • To review advancements in stem cell transplantation for Parkinson's disease.
  • To highlight the use of human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs) for generating dopaminergic cells for PD treatment.

Main Methods:

  • Review of experimental and clinical studies on stem cell transplantation in PD animal models and patients.
  • Focus on studies utilizing hESCs/iPSCs-derived dopaminergic precursor cells and neurons.

Main Results:

  • Stem cell transplantation, particularly using hESCs and iPSCs, shows potential for PD treatment.
  • Research is progressing in transplanting these cells into animal models and human patients.

Conclusions:

  • Stem cell therapy, especially with hESC/iPSC-derived dopaminergic cells, presents a significant therapeutic avenue for Parkinson's disease.
  • Further research is needed to develop clinical-grade dopaminergic cells for effective PD treatment and address future challenges.
