The appearance of SH-SY5Y cells post-thawing from liquid nitrogen suggests they may be experiencing stress or damage. Here are some key observations and recommendations:
Key Observations:
Cell Morphology: The cells appear sparse and irregular, with some showing rounded or fragmented shapes, which can indicate cell death or poor adherence.
Post-Thaw Challenges:Some cell death after thawing is normal due to the freezing and thawing process, but excessive death may suggest issues with freezing or handling. Cells stored at -80°C may recover better compared to those stored long-term in liquid nitrogen if freezing protocols or handling are inconsistent.
Recovery Potential: SH-SY5Y cells can recover if provided optimal conditions (e.g., appropriate density and growth medium). Dead cells and debris should be removed after 24 hours to promote recovery.
Recommendations for Recovery:
Immediate Actions:Replace the medium after 24 hours to remove non-viable cells. Ensure proper plating density for cell communication and recovery.
Long-Term Adjustments:Review your cryopreservation protocol to ensure proper cryoprotectant concentration and controlled cooling rates. Minimize air exposure during thawing and quickly transfer to pre-warmed medium.
Despite the initial stress, SH-SY5Y cells have a chance of recovery with proper care. Monitor their progress over the next 48 hours. If no improvement is seen, consider revisiting your cryopreservation protocol.
Un update on this, there has been a problem with the media. The SHSY5Y cells should recover from liquid Nitrogen in a similar morphology to -80C if exact thawing procedures are followed with adequate media (DMEM/F12, 1% pen/strep, 1%NEAA and 10% FBS).
