Insights

Transplanted stem cells struggle to survive in damaged heart tissue. New methods to assess mitochondria, the powerhouses of cells, can help improve stem cell survival for heart attack treatment.

Area of Science:

  • Cardiovascular Research
  • Regenerative Medicine
  • Cell Biology

Background:

  • Ischemic heart disease is a leading global cause of mortality.
  • Stem cell therapy offers potential for repairing heart muscle after infarction.
  • Poor survival of transplanted cells in the ischemic environment hinders efficacy.

Purpose of the Study:

  • To address the critical need for improved stem cell survival in myocardial infarction.
  • To present quantitative methods for assessing mitochondrial health in transplanted cells.
  • To facilitate the development of cytoprotective strategies for enhanced cell therapy.

Main Methods:

  • Assessment of mitochondrial morphology using quantitative techniques.
  • Measurement of mitochondrial membrane potential.
  • Quantification of mitochondrial reactive oxygen species (ROS) production.

Main Results:

  • Established reliable and reproducible methods for evaluating key mitochondrial parameters.
  • Provided a framework for assessing cell viability and function post-transplantation.
  • Highlighted the link between mitochondrial characteristics and stem cell survival.

Conclusions:

  • Accurate assessment of mitochondrial morphology and function is crucial for developing effective stem cell therapies.
  • These methods are essential for identifying strategies to improve transplanted cell survival.
  • This work supports the advancement of cell-based treatments for myocardial infarction.

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Adult Stem Cells01:33

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Embryonic Stem Cells

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Induced Pluripotent Stem Cells01:13

Induced Pluripotent Stem Cells

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...
