Summary
Human stem cells accumulate genetic changes during lab cultivation, posing risks for therapies. Extensive genetic screening and new regulatory standards are crucial for ensuring the safety of stem cell products.
Area of Science:
- Stem Cell Biology
- Genetics
- Regenerative Medicine
Background:
- Genomic instability is a significant challenge for stem cell-based therapies.
- Human stem cells exhibit biological changes during ex vivo cultivation, including chromosomal abnormalities and epigenetic alterations.
Purpose of the Study:
- To review the current status and emerging trends in genomic instability in human stem cells.
- To highlight the importance of genetic screening for stem cell product safety.
- To advocate for updated regulatory standards for therapeutic applications.
Main Methods:
- Comprehensive literature review of genomic instability in human stem cells.
- Analysis of biological changes during ex vivo cultivation.
- Evaluation of genetic screening methods and regulatory frameworks.
Main Results:
- Human stem cells undergo diverse genetic alterations (chromosomal, point mutations, telomere length, epigenetic) during ex vivo culture.
- Growing evidence points to genome plasticity as a risk factor in stem cell therapies.
Conclusions:
- Extensive genetic screening is essential for quality control and safety assurance of stem cell products.
- Implementation of new regulatory standards is needed to facilitate the clinical translation of stem cell therapies.

02:36DNA Damage can Stall the Cell Cycle
8.5K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

01:19Multipotency of Hematopoietic Stem Cells
3.1K
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...

02:40Cancer Stem Cells and Tumor Maintenance
4.3K
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.

01:14Maintenance of the ES Cell State
1.9K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

01:32Chromatin Modification in iPS Cells
1.5K
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...

4.5K
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...
