Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.0K
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

33.4K
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

32.1K
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

4.8K
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

15.6K
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 Cells

27.3K
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...

  • Cell Biology
  • Mitochondrial Biology
  • Stem Cell Biology

Background:

  • Mitochondria are vital for cellular energy production, pluripotency, differentiation, and reprogramming.
  • Stem cells display significant mitochondrial heterogeneity, impacting their function and fate.
  • Mitochondrial structure, function, and distribution are critical regulators of stem cell maintenance and differentiation.

Main Methods:

  • Review of existing literature on stem cell mitochondria.
  • Analysis of mitochondrial structure, function, and subcellular distribution.
  • Comparison of mitochondrial characteristics across different stem cell types and developmental stages.

Main Results:

  • Stem cells generally possess immature, spherical mitochondria with perinuclear distribution.
  • Pluripotent stem cells predominantly rely on glycolysis, while some naive stem cells utilize oxidative phosphorylation (OXPHOS).
  • Mitochondrial cristae development and localization influence oxygen consumption and ATP production, controlling stem cell fate.

Conclusions:

  • Mitochondrial heterogeneity is a crucial aspect of stem cell biology.
  • Understanding mitochondrial adaptability during development can reveal insights into cellular responses.
  • Investigating mitochondria in pluripotency may illuminate causes of mitochondrial diseases, aging, and inform regenerative therapies.
