A research team is the first in Texas to investigate whether plasma from COVID-19 survivors can be used in outpatient settings to prevent the onset and progression of the virus in two new clinical trials at UTHealth.
In one of the first studies addressing the role of sex hormones’ impact on stem cells in the gut, scientists outline new insights showing how a steroidal sex hormone that is structurally and functionally similar to human steroid hormones drastically alters the way intestinal stem cells behave, ultimately affecting the overarching structure and function of this critical organ. The authors found that ecdysone, a steroid hormone produced by fruit flies, stimulates intestinal stem cell growth and causes the gut of the female fruit fly to grow in size, as well as other critical changes.
New UCLA research conducted in mice could explain why some people suffer more extensive scarring than others after a heart attack. The study, published in the journal Cell, reveals that a protein known as type 5 collagen plays a critical role in regulating the size of scar tissue in the heart.
A new study shows that SARS-CoV-2, the virus that causes COVID-19 (coronavirus), can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be directly infected by the virus. The discovery, published today in the journal Cell Reports Medicine, was made using heart muscle cells that were produced by stem cell technology.
UC San Diego and Deerfield Management created Poseidon Innovation to support researchers working to advance disease-curing therapeutics by funding early stage projects and expediting the drug-development cycle. Poseidon announces it is funding three researchers.
Satya Dandekar, professor of microbiology and chairperson of the Department of Medical Microbiology and Immunology at UC Davis, honored by Prestigious NIH MERIT award for her illustrious journey in HIV research.
UCLA researchers and colleagues have received a $13.65 million grant from the National Institutes of Health to investigate and further develop an immunotherapy known as CAR T, which uses genetically modified stem cells to target and destroy HIV.
Using induced pluripotent stem cells (iPSCs) and deleting a key gene, researchers at University of California San Diego School of Medicine have created natural killer cells — a type of immune cell — with measurably stronger activity against a form of leukemia, both in vivo and in vitro.
As part of the Memorial Sloan Kettering – Hackensack Meridian Health Partnership, the two organizations have formed an Immunology Research Collaboration. Through this joint initiative, researchers can apply for funding to support innovative investigations to explore the power of the immune system and ways it may be harnessed to fight cancer.
Xiaojun “Lance” Lian, assistant professor of biomedical engineering at Penn State, has received a $500,000, five-year Early Career Development Program (CAREER) grant from the National Science Foundation (NSF).
Researchers at Mount Sinai have discovered that human acute myeloid leukemia (AML) stem cells are dependent on a transcription factor known as RUNX1, potentially providing a new therapeutic target to achieve lasting remissions or even cures for a disease in which medical advances have been limited.
Using skin cells from human volunteers, researchers at the University of Pittsburgh School of Medicine have created fully functional mini livers, which they then transplanted into rats. In this proof-of-concept experiment, the lab-made organs survived for four days inside their animal hosts.
For a while now, some plastic surgeons have been using stem cells to treat aging, sun-damaged skin. But while they’ve been getting good results, it’s been unclear exactly how these treatments – using adult stem cells harvested from the patient’s own body – work to rejuvenate “photoaged” facial skin.
In this study, researchers investigated if specific targeting of CD133+ glioblastoma with cutting-edge immunotherapy drugs could eradicate the most aggressive subpopulation of cells in the tumour. They also looked at the safety of CD133-targeting therapies on normal, non-cancerous human stem cells including hematopoietic stem cells which create blood cells and progenitor cells which can form one or more kinds of cells.
A recent study from the Mechanobiology Institute at the National University of Singapore has shown that rejuvenated fibroblasts can recover their ability to self-contract. This encouraging discovery holds great potential for applications in regenerative medicine and stem cell engineering.
Many patients with heart disease face limited treatment options. Fortunately, stem cell biology has enabled researchers to produce large numbers of cardiomyocytes, which may be used in advanced drug screens and cell-based therapies. However, current image analysis techniques don’t allow researchers to analyze heterogeneous, multidirectional, striated myofibrils typical of immature cells. In the Journal of Applied Physics, researchers showcase an algorithm that combines gradient methods with fast Fourier transforms to quantify myofibril structures in heart cells with considerable accuracy.
Oxidative stress can be pathological. Now researchers report that the other end of the redox spectrum, reductive stress, is also pathological. Reductive stress causes pathological heart enlargement and diastolic dysfunction in a mouse model.
