Summary
Human embryonic stem cells (HESC) may lose chromosomal stability during long-term in vitro culture. Regular genetic monitoring and cryopreservation at early passages are recommended to ensure HESC line integrity for research.
Area of Science:
- Stem Cell Biology
- Genetics
- Cell Culture
Background:
- Human embryonic stem cells (HESC) are crucial for biological, clinical, and toxicological research.
- HESC lines are generally expected to maintain chromosomal stability during culture.
Purpose of the Study:
- To investigate the potential for chromosomal instability in HESC during continuous in vitro culture.
- To highlight the need for further research into culture techniques affecting HESC chromosome stability.
Main Methods:
- Review of own experience and published reports on HESC culture.
- Analysis of chromosome constitution using karyotyping, CGH, FISH, and PCR.
Main Results:
- Evidence suggests that HESC may exhibit chromosomal instability during prolonged in vitro cultivation.
- The precise impact of various culture methods and extended culture periods on HESC chromosome stability requires further elucidation.
Conclusions:
- Regular chromosomal analysis of HESC lines is essential.
- Cryopreservation of HESC at low passage numbers and in large batches is recommended to safeguard against genetic alterations during extended culture.
