This wristband tells you what food to buy based on your DNA
Posted by Genevieve Klien in categories: bioengineering, biotech/medical, food, genetics, health
When an undiagnosed rare genetic disease caused his young son’s kidneys to fail, Professor Chris Toumazou vowed to find a way of uncovering hidden health risks.
The professor of biomedical engineering realised that, although his son’s condition could not have been prevented, the family could have managed his lifestyle very differently had they known about his condition.

Doctors Report First US Tests of Gene Editing for Cancer
Posted by Quinn Sena in categories: bioengineering, biotech/medical, genetics
Doctors have reported on the first attempts in the United States to use gene editing to help patients fight cancer.
The doctors say one form of gene editing appeared to be safe when tested in three patients. But it is not yet known what long-term effects the method will have on cancer treatment or patient survival rates.
A gene editing tool called CRISPR/Cas9 was used in the tests, which were recently reported in a medical study. The method was discovered in recent years as a way to change the genetic material that make up a person’s DNA.

Engineering biomimetic microvascular meshes for subcutaneous islet transplantation
Posted by Saúl Morales Rodriguéz in categories: 3D printing, bioengineering, biotech/medical
To successfully engineer cell or tissue implants, bioengineers must facilitate their metabolic requirements through vascular regeneration. However, it is challenging to develop a broad strategy for stable and functional vascularization. In a recent report on Nature Communications, Wei Song and colleagues in the interdisciplinary departments of Biological and Environmental Engineering, Medicine, Mechanical and Aerospace Engineering, Clinical Sciences and Bioengineering in the U.S. described highly organized, biomimetic and resilient microvascular meshes. The team engineered them using controllable, anchored self-assembly methods to form microvascular meshes that are almost defect-free and transferrable to diverse substrates, for transplantation.
The scientists promoted the formation of functional blood vessels with a density as high as ~200 vessels per mm-2 within the subcutaneous space of SCID-Beige mice. They demonstrated the possibility of engineering microvascular meshes using human induced pluripotent stem-cell (iPSCs) derived endothelial cells (ECs). The technique opens a way to engineer patient-specific type 1 diabetes treatment by combining microvascular meshes for subcutaneous transplantation of rat islets in SCID-beige mice to achieve correction of chemically induced diabetes for 3 months.
Vasculature is an essential component of any organ or tissue, and vascular regeneration is critical to successfully bioengineer implants. For instance, during cell replacement therapy for type 1 diabetes (T1D), transplanted insulin producing cells rely on the vasculature to function and survive. Bioengineers often use vascular endothelial cells such as human umbilical vein endothelial cells (HUVECs) to spontaneously assemble into tubular structures within the extracellular matrix (ECM). But the resulting structures can be random, uncontrollable and less efficient for microvascular regeneration. Scientists have recently developed three-dimensional (3D) printing techniques to engineer controlled cellular constructs with embedded vessels. However, it remains challenging to 3D print resilient and transferrable, high-resolution, microvasculature.

Why Designing Our Own Biology Will Be the Next Big Thing in Medicine
Posted by Paul Battista in categories: bioengineering, biotech/medical, genetics
While the public is still imagining the future to be very much like the past, the researchers at the forefront of genetics are planning to redesign human bodies, to make us more long-lived, more resilient to disease, more strong and (I hope) more intelligent.
In a talk at Exponential Medicine, Jane Metcalfe said that tools like gene editing and synthetic biology could make design the next big thing in medicine.
