Cellular & Molecular Biology Letters
|October 30, 2015
Summary
Long-term cultivation of somatic stem cells is crucial for regenerative medicine but carries risks. This review examines cellular changes during culture to ensure safe clinical applications.
Area of Science:
- Stem Cell Biology
- Regenerative Medicine
- Tissue Engineering
Background:
- Somatic stem cells offer self-renewal and plasticity for therapeutic applications.
- In vitro culture is necessary to obtain sufficient cell numbers for clinical use.
- Long-term cultivation of stem cells poses a risk of cellular transformation.
Purpose of the Study:
- To review the biological features and cellular events during long-term somatic stem cell cultivation.
- To assess the safety of using cultured somatic stem cells in clinical practice.
Main Methods:
- Literature review of studies on somatic stem cell biology and cultivation.
- Analysis of cellular events associated with long-term in vitro culture.
- Evaluation of transformation risks in cultured stem cells.
Main Results:
- Long-term culture can lead to genetic and epigenetic alterations in somatic stem cells.
- Cellular transformation increases the risk of tumorigenicity.
- Understanding these changes is vital for risk assessment.
Conclusions:
- Safe clinical application of somatic stem cells requires careful monitoring during long-term cultivation.
- Mitigation strategies for cellular transformation are essential for regenerative medicine.
- Further research is needed to optimize safe stem cell culture protocols.

Cancer Stem Cells and Tumor Maintenance
6.4K
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.

Induced Pluripotent Stem Cells
6.3K
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).

Mesenchymal Stem Cells
6.0K
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...

Replicative Cell Senescence
4.6K
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...

Stem Cell Therapy for Tissue Regeneration
4.9K
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.
