They have identified the core genes that allow stem cells to exist in distinct functional states
The Pfizer-BioNTech and Moderna COVID-19 vaccines help keep people with weakened immune systems out of the hospital if they are infected, but dont offer as much protection as they do in people with fully functioning immune systems, according to a study. The results support immunocompromised people receiving three doses of either vaccine, plus a fourth shot as a booster, the researchers said
In October, a 38-year-old man walked into the civic-run King Edward Memorial (KEM) Hospital with tinnitus a ringing noise in both his ears.
Stem cells can be used to study development Stem cells may help us understand how a complex organism develops from a fertilised egg. In the laboratory, scientists can follow stem cells as they divide and become increasingly specialized, making skin, bone, brain, and other cell types. Identifying the signals and mechanisms that determine whether a stem cell chooses to carry on replicating itself or differentiate into a specialized cell type, and into which cell type, will help us understand what controls normal development.

BURLINGTON, Mass.--(BUSINESS WIRE)--PharmaEssentia Corporation (TPEx: 6446), a global biopharmaceutical innovator based in Taiwan leveraging deep expertise and proven scientific principles to deliver new biologics in hematology and oncology, today announced that the U.S. Food and Drug Administration (FDA) has approved BESREMi (ropeginterferon alfa-2b-njft) for the treatment of adults with polycythemia vera (PV). BESREMi is an innovative monopegylated, long-acting interferon, which exhibits its cellular effects in polycythemia vera in the bone marrow.
Introduction Coronavirus-2019 disease (COVID-19) is a newly diagnosed infectious disease, which is caused by the severe acute respiratory syndrome corona virus-2. It spread quickly and has become a major public health problem throughout the world.1 When numerous cases of severe respiratory illnesses were reported in the Wuhan city, Hubei province, China, by the end of 2019, it signaled the start of the main challenge for a human being.
About stem cells Stem cells are the foundation of development in plants, animals and humans.
A team of researchers at Stanford Medicine has used genetically engineered human cells to create a model for liver fibrosis, a condition associated with liver damage, scarring and even liver failure. The new model stems from a previous method that the team developed in 2017 to coax adult stem cells, which can develop into different types of cells, to form the many categories of cells that are found in liver
Human pluripotent stem-cell derived cardiomyocytes (hPSC-CMs) have great potential as a tool for studying cardiovascular disease and associated treatments, but more insights into hPSC-CM biology are needed before their full potential can be realized.
