iPS Cell Differentiation01:22

iPS Cell Differentiation

3.3K
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

6.4K
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).

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...

Chromatin Modification in iPS Cells

2.3K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

EPS and iPS Cells in Disease Research

3.5K
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,...

Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

2.9K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Area of Science:

  • Regenerative Medicine
  • Stem Cell Biology
  • Orthopedic Research

Background:

  • Articular cartilage (AC) injuries in adults do not heal spontaneously, often leading to osteoarthritis.
  • Bone defects, especially large ones from trauma or surgery, also exhibit incomplete healing.
  • Cell therapy offers potential for musculoskeletal regeneration, with human induced pluripotent stem cells (hiPSCs) being a promising source due to their proliferative capacity and ethical advantages over embryonic stem cells.

Purpose of the Study:

  • To develop and evaluate protocols for in vitro chondrogenesis and osteogenesis from hiPSCs.
  • To assess the potential of hiPSCs for in vivo cartilage and bone regeneration using animal models.

Main Methods:

  • Established in vitro protocols to induce chondrogenesis (cartilage formation) and osteogenesis (bone formation) from hiPSCs.
  • Utilized animal models to evaluate the efficacy of hiPSC-based therapies for repairing cartilage and bone defects in vivo.

Main Results:

  • Demonstrated successful in vitro chondrogenesis and osteogenesis from hiPSCs.
  • Showcased the potential of hiPSCs for in vivo cartilage and bone regeneration in preclinical animal studies.

Conclusions:

  • Developed protocols for utilizing hiPSCs in regenerative medicine for cartilage and bone repair.
  • hiPSCs represent a viable cell source for future therapeutic strategies targeting musculoskeletal regeneration.
