Nanotechnology application in stem cells for patient’s benefit
16 February 2009Researcher’s at Northwestern University are looking for new approach to many health problems. Samuel I Stupp have developed a synthetic molecule peptide amphiphiles (PA), which the researchers took for the study. For present study researchers combine peptide amphiphiles with many other molecules and got many new structures that can be useful in treating a number of medical conditions including spinal cord injuries, Parkinson’s disease and diabetes.
Capito, a postdoctoral fellow at the Northwestern University have recently combine peptide amphiphiles to hyaluronic acid and found that the combination produces a biopolymer that is found in joints and cartilage in humans. The product of the combination of peptide amphiphiles and hyaluronic acid is obtained in the form of a self assembling sacks membrane structures. These membrane structures self assemble to form nanoscale to microscale structures that can have unique physical properties.
The research team while creaing sack, carefully injected the hyaluronic acid solution into the peptide amphiphiles solution, which have smaller molecules. This forms a closed sack trapping hyaluronic acid inside the membrane. Now by allowing engulfing of stem cells inside the sacks by self-assembling process, the culture studies were carried out. Researchers were able to make tailor made bioactive regions in the sacks and therefore can incorporate a number of designs in these sacks structures, which will ultimately provide many new opportunities in the creation and delivery of stem-cells.
