Summary
Researchers developed a novel technique to replace human embryonic stem (hES) cell nuclei with somatic cell nuclei, creating patient-specific
Area of Science:
- * Stem cell biology and regenerative medicine.
Background:
- * Somatic cell nuclear transfer (SCNT) is crucial for patient-specific stem cell development.
- * Human embryonic stem (hES) cells may contain reprogramming factors, but nucleus replacement is challenging.
Purpose of the Study:
- * To develop a novel technique for replacing hES cell nuclei with somatic cell nuclei.
- * To create patient-specific cell lines with donor somatic cell genotypes and hES cell stemness.
Main Methods:
- * Developed an original technique involving the fusion of somatic cells with hES cells.
- * Achieved complete replacement of hES cell nuclei with somatic cell nuclei, forming 'cybrids'.
Main Results:
- * Resulting 'cybrids' exhibited the genotype of donor somatic cells.
- * 'Cybrids' retained the 'stemness' characteristics of recipient hES cells.
- * Isolated colonies contained a mixture of cybrids, recipient cells, and hybrid cells.
Conclusions:
- * A novel fusion technique enables somatic nucleus replacement in hES cells.
- * This method holds potential for generating patient-specific stem cells.
- * Further purification is required for practical application of this technique.

01:29Somatic to iPS Cell Reprogramming
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 for this...
01:24Methods of Nuclear Reprogramming
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for injury repair.
01:14Introduction to Nuclear Reprogramming
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...
01:32Chromatin Modification in iPS Cells
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...

01:06Induced Pluripotent Stem Cells
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).

01:13Induced 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 called induced pluripotent stem...
