Stem Cell Research. Clinical application

An interesting branch of medicine engineering is the stem cell research. This unique branch of medicine engineering is presently undergoing a critical transition. Yet it continues to be a potential component of both medical engineering as well as medical practice.

Many people lose cells due to injury or degenerative diseases that have no cure at present. Medicine engineering experts have tried a wide range of experimental models to solve this problem. This has resulted in a gift by the medicine engineering science, the cellular grafting, which is a unique type of cell based therapy.

The method that is the most suitable stem cell research and therapy, as devised by the medicine engineering studies, is the magnetic resonance imaging methods. They produce non-evasive images of opaque tissues. If on the other hand, the cells are transplanted, medicine engineering has the answer in tracking them by MRI, after making them MR visible.

In fact the medicine engineering studies are more concentrated in this regard in modeling novel contrast agents into stem cells and developing specific tagging molecules to deliver efficient amounts of contrast agents into stem cells.
The concern of the specialists in this case is that, the methods for monitoring implanted stem cells, non-invasively in “vivo”, a type of research approach, will expedite improvement of opportunities for stem cell based therapies.

So far as medicine engineering is concerned, the specific aims relating to the program of stem cell research are as follows:

Increasing efficiency of polymer-enveloped super-paramagnetic nanoparticles;
Providing adequate MR contrast agents to cells;
Achievement of intracellular retention for medicine engineering;
Efficient “relaxivity” to expedite processing factors in medicine engineering;
Improving the “vivo” signal-to-noise ratios and tolerable of toxicity levels;
Developing generic methodologies for tracking of cells for magnetic resonance imaging, which would help medicine engineering in identifying the toxic levels and noise ratio.

Another type is the cardiac regenerative medicine.
This is one branch of medicine engineering, where work is performed with bone marrow, skeletal myoblast, and embryonic stem cells. Medicine engineering takes for experimentation, both, human being and mouse, using cell co-culture. In this process, medicine engineering has also developed the system of tissue engineering to create valve implants.
The process that is provided through medicine engineering is to combine embryonic stem cells with novel biomaterials. This facilitates grafting and heart patch development.

Medicine engineering, after a long research, has established the fact that first trimester fetal blood and tissues are richer in MSC contents compared to the adult MSC. These fetal MSC engraft readily in the bone marrow of every pregnant women.
Medicine engineering shows that these cells contribute to the tissue repair and post-reproductive females. It is believed that such fetal MSC has the therapeutic potential of becoming the source of protein or gene delivery, especially in diseases relating to genetic deficiencies and diseases, resulting from such shortcomings.

Therefore, one of the main focuses of medicine engineering is on use of fetal MSC in tissue repair, thereby doing away with the effects of diseases resulting from tissue deficiencies.
Studies of medicine engineering have also revealed that stem cells can be directly and reproducibly isolated from “vivo” source and therefore they have quite significant clinical application potential.
