The cell technology breakthrough helps replicate parts of the human body

There has never been a cell intervention technique for the human body to reproduce damaged parts as it is now when researchers from Northwestern University (NU, USA) produce self-produced "matrices". However, it is possible to self-assemble like "matrices" that exist in the body , surrounding cells to protect and direct these cells to move to the necessary locations.

Samuel I. Stupp, director of NU's Nano Biotechnology Research Institute, said the result marked a big leap in the study of biological regeneration technology using micro synthetic materials.

Starting at the molecular level, this method is a design from the core using ideas in nanotechnology.

The team at NU has begun implementing experiments focused on bone or cartilage regeneration, in which these "matrices" surround existing or tightly bound cells around development factors (including Functional proteins are often taken to parts of the body to support the regeneration process when there is damage.

The advantage of this method is that "matrices" are made of organic materials.(Source: Medical News Today).

The experiment showed that the "matrix" technology helped solve the regeneration problem without "cutlery touch". Normally, to perform spinal joint surgery such as bone tissue grafting, doctors must follow the steps that begin by taking a piece of bone from another part of the patient's body (usually from the hip). , then inserted to connect the vertebrae.

But with new technology, there is no need to take in other bones to put in, so there is no need to mobilize too many development factors, reduce the cost by half, the level of pain also decreases while the risk of failure also lower.

In fact, a few years ago, the research team led by Professor Stupp used this technology to control molecules involved in cell-level regeneration and repair to help a disabled mouse. can walk normally.

After several years of research and development, the regenerative drug using this technology has been improved by the research team and reached a high level of completion, so the group contacted the US Food and Drug Administration (FDA). ) to be licensed for a clinical trial of human vertebral reconstruction, helping to nourish bones between vertebrae.

To achieve absolute success, scientists need to combine stem cells with this technology to create parts in the body.

Once these two factors are successfully combined, the team will not only prevent the possibility of early elimination of cells but also produce more commands for cells such as cell division, self-replication. copy or transform into another cell form.

The advantage of this method is that "matrices" are made of organic materials, so they can completely dissolve without leaving unnecessary and potentially dangerous substances in body.
