CO2 incubators

CO₂ incubators play an important role in medical research wherever cell cultures have to be observed in as sterile and meticulous a way as possible. They keep unwanted microbes away from the cultures, thus providing the ideal conditions for growth. Different CO₂ incubators offer different methods of preventing contamination in the incubation chamber. This article will tell you which product details you need to take note of to achieve the best results in various fields, such as stem cell therapy, regenerative medicine, and plastic surgery.

CO₂ incubators create the optimum conditions for:

  1. Incubating human skin cells for life-saving skin grafts
  2. Fighting diseases using stem cell research
  3. Offering stem cell therapy as a viable alternative to surgery
  4. Plastic surgery, anti-ageing therapies, tissue repair, and dermatological treatments
  5. Multiplying human skin cells for healing processes in regenerative medicine


1. CO₂ incubators incubate human skin cells for life-saving skin grafts

Regenerative medicine is one of the most promising fields of modern research. Dead tissue and damaged organs can be healed by restoring dysfunctional cells. To achieve this, skin is removed from the patient, multiplied in the CO₂ incubator, and later implanted back into the patient. This new form of therapy is of ground-breaking significance for victims with extensive burns, as the significant scars which form as a result of traditional transplantation procedures can be avoided.

Human skin can only be produced with a great deal of effort and by fulfilling the strictest of safety requirements. Up to now, laboratory staff had to carry out laborious cleaning procedures before they were permitted to enter the “cleanroom” where CO₂ incubators are located. However, since the demand for artificially created skin cells can barely be met, technicians started searching for a more efficient solution. They finally came up with the idea of directly integrating the CO₂ incubator into the isolator. This means that laboratory staff can work in the CO₂ incubator room much longer without increasing the risk of contamination.

2. Fighting diseases using stem cell research

Progress in stem cell research is crucial for fighting diseases and especially for cancer therapy. Stem cell therapy can be used to repair or even replace dysfunctional cells and organs with tissues grown in vitro. As such, stem cell research provides the scientific foundation for regenerative medicine. When it comes to handling cell cultures, sterile conditions and maximum safety are of the utmost importance. Therefore, your CO₂ incubator should also offer an automatic sterilization function. This reduces the risk of potential external contamination to an absolute minimum.

3. Offering stem cell therapy as a viable alternative to surgery

Regenerative medicine, in the form of stem cell therapy, has managed to revolutionize research in cardiac surgery. Stem cell therapy is now increasingly given precedence over open-heart surgery. The process can be described thus: tissue and cell clusters are grown in the CO₂ incubator and implanted into the patient via cell transplantation. There are two ways of producing these stem cells:

  1. The patient’s own cells are harvested, then multiplied in the CO₂ incubator
  2. Living tissue such as heart valves or blood vessels are grown from scratch in the CO₂ incubator

The subsequent sterilization process is important when propagating stem cells in the CO₂ incubator. Ideally, your CO₂ incubator will feature an automatic hot air sterilization function. The sterilization cycle as a whole should meet the requirements of the European Pharmacopoeia.

4. CO₂ incubators for plastic surgery, anti-ageing therapies, tissue repair, and dermatological treatments

CO₂ incubators are also important tools for personalized autologous stem cell therapies. These therapies involve preparing the body's own cells for use in applications such as plastic surgery, anti-ageing therapies, tissue repair, or dermatological and orthopaedic treatments. Once tissue has been recovered, the stem cells are extracted and isolated from it. This comes with a risk of contamination, which is why comprehensive sterility tests are performed in the CO₂ incubator, where the cell cultures will later multiply. Final genetic tests in the CO₂ incubator ensure that maximum safety is achieved before the cells are implanted back into the patient.

Incubators for Research

5. CO₂ incubators multiply human skin cells for healing processes in regenerative medicine

The question of how to treat patients with extensive heat-related injuries presents modern medicine with several challenges. Staff at the German Institute for Cell and Tissue Replacement (DIZG) produce autologous cell cultures in order to help patients in German burn centres. These skin cell transplants, which have been grown in CO₂ incubators, are used on patients when 60% of their body surface is covered by second or third-degree burns. Often, regenerative medicine is the only chance for such patients to heal.

When producing or multiplying cell cultures, your CO₂ incubator should have the lowest possible risk of contamination. By contrast, the fans often installed in traditional incubators, large-scale racks, and freestanding fixtures often represent a high risk of contamination, which can result in an enormous risk to the patient’s health.
