Growing Blood Vessels John Rawls
Regenerative Medicine • The process of replacing or regenerating human cells, tissues, or organs to restore or establish normal function • Growing tissues and organs in a lab • Implant in body successfully • Could solve the problem of organ transplant rejection and the shortage of organs • Stem Cells
Polyethylene Glycol • Also called PEG and Carbowax • Nontoxic plastic • Scientists modify PEG to mimic the body’s extracellular matrix • Combined with two types of cells required of blood vessel formation • Creates hydrogels filled with living cells and growth factors
The Result • Cells are tagged with fluorescent markers • Created capillaries and vessels • Successfully implanted in mice • Normal blood flow recorded
What is to become? • Current method of creating blood vessels takes too much time • Other ways to create blood vessels and capillaries are being researched • “Two-photon liphography” • Allows more control
