"What happened next?" Tang Shun asked.
"Then I discovered the problem was with the water bath," Weber said. "When I thawed the cryopreservation tube during cell revival, I used the water bath. The first time I did it, the water was clean. Three months later, the water in the bath grew bacteria, invisible to the naked eye, but during thawing, the seal of the cryopreservation tube might have been contaminated with bacteria, polluting my cells. The cells were fine in the cryopreservation tube, but once they were planted and cultured for a few days, the bacteria gradually developed, and the cell's condition deteriorated."
Everyone was stunned.
"It's that simple?"
Weber said, "It's that simple, but to find this reason, it took me three months. Today's reminder from Professor Yang reminded me of something from ten years ago."
