Cell-free Fetal Nucleic Acids in Amniotic Fluid

L. Hui, D.W. Bianchi https://academic.oup.com/humupd/article/17/3/362/1387873 Cell-free fetal nucleic acids have mainly been examined in maternal plasma. Cell-free fetal nucleic acids have been found in greater concentrations in amniotic fluid than in maternal plasma. It is physiologically distinct from nucleic acids found in maternal plasma. What is Amniotic Fluid? Amniotic fluid is formed in the first…

New Nanotech to Detect Cancer Early

Dr. Joshua Smith is a research scientist and team lead for IBM’s Nanobiotechnology Program. Around forty percent of the population will receive a cancer diagnosis within their lifetime. Accurate early diagnosis drastically increases the survival rate of most cancers. Current methods for diagnosis are invasive, costly, and not reliably accurate. Dr. Joshua Smith and his…

A New Way to Grow Bone

Molly Stevens Molly Stevens is a researcher and head of a bio lab that focuses on creating new bio materials that can be used in disease diagnosis and towards repairing bone and human tissue. They developed a gel that is injected into the periosteum layer. It creates a cavity that promotes the proliferation of the…

Can the Damaged Brain Repair Itself?

Dr. Chandran is currently serving as the Director of Centre for Clinical Brain Sciences at the Euan MacDonald Centre and Anne Rowling Regenerative Neurology Clinic at the University of Edinburgh. 35 million people worldwide suffer from degenerative neurological disorders costing an average of 700 billion dollars annually, yet there is still not a recognized effective…

Self-assembling Peptide Scaffolds For Regenerative Medicine

John B. Matson, Samuel I. Stupp Bio-materials made from small peptide chains are ideal for creating scaffolds for tissue regeneration. Small peptides can assemble into spheres, cylinders, tubes, and many other useful scaffolding structures. Classes of Filamentous Supra-molecular Scaffolds Peptide amphiphiles are short chain peptides with a hydrophobic tail attached to a lipid chain capable of self…

Human Skeletal Stem Cell Found

  C.K.F. Chan et al., “Identification of the human skeletal stem cell,” Cell, doi:10.1016/ j.cell.2018.07.029, 2018.  Skeletal stem cells in humans, the bone marrow support cells, have been discovered. Researchers determined that these stem cells are self replicating and multipotent. Nonhematopoietic cells were taken from a human fetal femur and separated from blood precursors. The non…

A Bioengineered Factory for T-cells

Harvard University John A. Paulson School of Engineering and Applied Sciences Bone marrow transplants utilizing hematopoietic stem cells are currently being used as an effective treatment to combat life threatening cancers and infections. A transfusion of blood stem cells from a matched donor is injected into the patient to “reset the blood and immune system.”…
