Bioscaffold Review
"Every 30 seconds, a patient dies from a disease that could be treated with tissue replacement."
This shocking observation, presented by Dr. Anthony Atala, emphasizes the need for regenerative
technology. |
One improvement which will assist in the evolution of regenerative technology is the
investigation of bioscaffolds. Bioscaffold technology is expected to
revolutionize the medical industry in the next decade by providing a rapid solution to tissue replacement
needs. Utilizing specialized materials, a 3D architecture is created with
highly specific parameters, such as surface properties or porosity, to encourage desired cell activity and cause
tissue growth.
Bioscaffolding is the use of biocompatible and bioresorbable materials to
construct a 3d structure comparable to the implant tissue area, in order to promote tissue regeneration and
injury recovery. The structure is seeded with native differentiable cells and cell adhesion proteins in order to
encourage cell adhesion and tissue regeneration. The matrix is also consistently porous, which further promotes
cell adhesion and differentiation at a controlled rate. The scaffold
must be designed to withstand and effectively transfer local stresses evenly across the area of implantation
during the degradation period. Also, the degradation properties are
catered to match the cell differentiation rates and extracellular matrix deposition rates of the implant site in
order to provide continuous support throughout the repair process. Materials used for the scaffold construction must be chosen appropriately to minimize
adverse reaction and maximize cell adhesion and differentiation.
Bioscaffold is mainly utilized in bone and cartilage
regeneration. However, it is also successfully implemented in areas of
skin and muscle regeneration and possibilities for organ regeneration are being
researched. An example of its use in bone regeneration is in the
fracture repair. If the damage is substantial, there may not be
enough bone present to reform the original structure. In order to
repair the area quickly and effectively, a scaffold, which has been seeded with the appropriate cells, may be
implanted at the site using a bioadhesive. This scaffold will
degrade over time and promote the growth of new bone.
The importance of this technology is evident in almost any medical procedure
involving organ repair or replacement. While a regular transplant
would require both time on an organ waiting list and extended recovery time with the possibility of rejection,
bioscaffold use mitigates these obstacles. Because the scaffold is
seeded, or loaded, with stem cells native to the patient’s body, the chance of rejection is greatly
decreased. Also, the tissue can be quickly grown on the bioscaffold,
avoiding the risky wait of an organ waiting list. The use of a
bioscaffold tailored to the repair region decreases the time necessary for the cells to repair surrounding
tissue, greatly decreasing recovery time. The culmination of these
advantages ultimately leads to a faster and easier recovery from an expedited replacement
surgery.
The implementation of bioscaffolds for regeneration technology will not only
revolutionize the patient experience, but it will expand the medical job market
tremendously. Within the next decade, bioscaffold use will give
rise to the need for organ and tissue designers, tissue and organ preparation experts, and specialized
surgeons experienced in bioscaffold implantation. This new
industrial expansion will greatly stimulate the job market and make exciting and exploratory jobs
available.
