A renowned scientific institute in Munich is studying the genetic form of leukemia. When someone is diagnosed with leukemia, they have a blood test carried out straight away. They also undergo a detailed genetic analysis. If, once the patient's DNA code has been established, a particular gene is missing, tests are performed on mice to see whether this defect also causes the mice to develop the disease in five to seven years' time. A defective human gene can also be injected into a mouse. The results provide insights into the origins of the genetic form of leukemia and enable new medication to be developed.
In order to work with mouse models, an egg cell first needs to be fertilized with sperm in vitro. This produces a zygote, which is then incubated in petri dishes at 37 °C in BINDER incubators at the institute in Munich. After several days, an undifferentiated cell clump has developed, providing the scientists with several identical cells. They can now begin to deactivate the gene of interest.
The modified cell is once again incubated in a BINDER incubator at 37 °C for several days. This again produces several cells of the same type. These cells are removed from the simulation chamber and injected into a mouse. The cells that
have not been modified can also be injected. This enables the scientists to make comparisons.
This is, however, also when the period of waiting and observing begins. The laboratory staff need to keep an eye on developments. If a mouse with the same genetic defect as the human with leukemia also develops the disease, this may indicate what is causing it and enable the scientists to make great strides in their research.
BINDER simulation chambers are crucial to the institute's work in this area. 13 CB 160 incubators are currently in use in the new premises in Munich and more will be added in the future with the aim of enabling new insights in the field of cancer research. During our visit, the scientists at the institute explained why they work with BINDER chambers: “BINDER products provide lots of space so we can cultivate lots of cells. The quality is excellent, as are the service and
