Summary
Researchers developed a new method to create human primordial germ cell-like cells (PGCLCs) from stem cells. This technique uses specific gene expression, SOX17 and PRDM1, offering a vital tool for studying germ cell development and reproductive medicine.
Area of Science:
- Developmental Biology
- Stem Cell Biology
- Reproductive Biology
Background:
- Human primordial germ cell (PGC) development is crucial for gamete formation but difficult to study directly in embryos.
- Previous methods for generating PGC-like cells (PGCLCs) from pluripotent stem cells (PSCs) relied on cytokine cocktails.
- The transcription factors SOX17 and PRDM1 are key PGC specifiers, but their balanced expression is critical for germ cell fate versus endoderm differentiation.
Purpose of the Study:
- To describe a detailed protocol for PGCLC differentiation using balanced induction of SOX17 and PRDM1.
- To provide an accessible experimental platform for studying human PGC development and its potential dysfunctions.
- To enable PGCLC induction in other mammalian species.
Main Methods:
- Utilized human pluripotent stem cells (PSCs).
- Induced expression of PGC specifiers SOX17 and PRDM1 in a balanced manner.
- Optimized differentiation protocol without the need for cytokine cocktails.
Main Results:
- Successfully generated PGCLCs from PSCs by balanced SOX17 and PRDM1 induction.
- Demonstrated that this method bypasses the requirement for BMP and other cytokines.
- Showcased the protocol's applicability to other mammalian species with SOX17-expressing PGCs.
Conclusions:
- Balanced induction of SOX17 and PRDM1 provides a robust method for PGCLC generation.
- This protocol advances the study of germ cell biology and its applications in reproductive technologies.
- The method offers a valuable tool for understanding PGC development and potential related disorders.

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...

01:29Somatic to iPS Cell Reprogramming
2.2K
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...

01:24Methods of Nuclear Reprogramming
1.8K
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...

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...

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...
