Stem Cell Culture

5.8K
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

Multipotency of Hematopoietic Stem Cells

3.6K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Stem Cell Therapy for Tissue Regeneration

4.4K
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.

Cancer Stem Cells and Tumor Maintenance

5.5K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

iPS Cell Differentiation01:22

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.

Mesenchymal Stem Cells01:19

Mesenchymal Stem Cells

5.3K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Area of Science:

  • Cardiovascular Biology
  • Regenerative Medicine
  • Cell Metabolism

Background:

  • Cell-based therapies show promise for cardiac repair but suffer from low cell survival (<1%) in the cardiac environment.
  • Stem cell metabolism is crucial for proliferation, stemness, and differentiation, influencing cell function and survival.

Purpose of the Study:

  • To review the role of stem cell metabolism in cardiac repair.
  • To explore how metabolic reprogramming can enhance cell-based cardiac therapeutics.

Main Methods:

  • Literature review of preclinical and clinical studies on stem cell therapy for cardiac repair.
  • Analysis of stem cell metabolic pathways (glycolysis, oxidative phosphorylation) and their regulation.

Main Results:

  • Stem cells primarily use glycolysis for energy, supporting proliferation and biosynthesis.
  • Metabolic shifts occur during stem cell commitment, altering function.
  • Environmental signals profoundly impact stem cell metabolism and survival.

Conclusions:

  • Stem cell metabolism is a critical target for improving cell-based cardiac repair.
  • Reprogramming stem cell metabolism offers a promising strategy to enhance therapeutic efficacy and cell survival.
