Process could be similar to how first living cells formed; applications to industry possible UNIVERSITY OF HOUSTON University of Houston associate professor of chemistry, Vassiliy Lubchenko, is reporting a new finding in Nature Communications on how sickle cells are formed. Lubchenko reports that droplets of liquid, enriched in hemoglobin, form clusters inside some red blood cells when two hemoglobin molecules form a bond – but only briefly, for one thousandth...

Decoding Cells to Unlock Stem Cells’ Potential
Posted Today Stem cells are jacks of all trades, capable of alleviating the consequences of such diverse pathologies as heart attacks, strokes and cancer. However, stem cell therapies have been hampered by possible side effects, which are frequently hard to predict. One way around this conundrum is to understand how stem cells conjure up their therapeutic...

Manuka honey to kill drug-resistant bacteria found in cystic fibrosis infections
Manuka honey could provide the key to a breakthrough treatment for cystic fibrosis patients following preliminary work by experts at Swansea University. Dr. Rowena Jenkins and Dr. Aled Roberts have found that using Manuka honeycould offer an antibiotic alternative to treat antimicrobial resistant respiratory infections, particularly deadly bacteria found in Cystic Fibrosis (CF) infections. Using lung tissue from pigs, experts treated grown bacterial infections mimicking those seen in CF patients with Manuka honey. The results...

Princeton scientists bioengineer a cellular speedometer
Many kinds of cells can sense flow, just as our skin cells can feel the difference between a gentle breeze and a strong wind. But we depend on feeling the force involved, the push-back from the air against us. Without that push, we can’t distinguish speed; when the windows are closed, our skin can’t feel any difference...

Pluripotency or differentiation — That is the question
HELMHOLTZ ZENTRUM MÜNCHEN – GERMAN RESEARCH CENTER FOR ENVIRONMENTAL HEALTH Induced pluripotent stem cells can turn into any type of cell in the body or remain in their original form. In the current edition of Molecular Cell, scientists from the Helmholtz Zentrum München describe how cells “decide” which of these two directions to take. During their research, they...

Handheld Skin Bioprinter Heals Deep Open Wounds With Patient’s Own Cells
The human organism has a number of physiologic processes that work together to heal skin wounds. Sometimes wounds are so large and difficult that these healing mechanisms simply can’t access damaged tissues. Researchers at Wake Forest Institute for Regenerative Medicine in North Carolina are now reporting the development of a bioprinter that uses a patient’s own skin cells to heal wounds faster and more consistently. The device is...

Team gets a closer look at how proteins meet on the cell membrane
JUPITER, FL – Oct. 10, 2018 – Scripps Research scientists have uncovered the workings of a critical process in cell survival. Their study, published recently in the Proceedings of the National Academy of Sciences, is the first to show exactly how a protein called talin activates another critical protein, called integrin, to do its job...

What are Exosomes?
What are exosomes? For many years, exosomes were considered to be transporters of cellular waste, but they are now recognized for their essential role in intercellular communication and transportation. In this article: Definition of Exosomes Exosome Size Exosome Sources Exosome Characteristics Exosome Review Exosome Research Cancer Exosomes Exosome Therapeutics First EV Therapeutic Entering Human Trial...

38 Athletes Who Have Had Stem Cell Treatments
July 25, 2018 By Cade Hildreth (CEO) More and more athletes are turning to stem cell treatments because the pressure and expectation to get back on the field are high and access to these experimental therapies is increasing. Athletes commonly suffer serious injuries that put their health and careers on the line. Most of them turn to...

Discovery of a new on/off switch affecting cell-to-cell communications
A new study published in the prestigious journal Molecular Cell INSTITUT NATIONAL DE LA RECHERCHE SCIENTIFIQUE – INRS Cellular functions rely on several communications networks that allow cells to rapidly respond to signals affecting the organism. A new study published in the prestigious journal Molecular Cell has revealed a mechanism that shuts down a major cell-to-cell communications...
