By examining the gene expression patterns of single cells from human fetal kidneys, researchers created a map that demonstrates the trajectories of cell states in the developing kidney and that identifies characteristics associated with kidney diseases.
Results from the study will be presented at ASN Kidney Week 2023 November 1–November 5.
Philadelphia, PA (November 3, 2023) — Scientists have examined the gene expression patterns of single cells from 5 human fetal kidneys to create the most complete atlas of the fetal kidney to date. The research will be presented at ASN Kidney Week 2023 November 1–November 5.
The atlas, which was based on a total of 65,348 cells, demonstrates the trajectories of cell states starting from a progenitor population to mature cell types. By examining properties within this map, investigators identified the transitions between different cell states and defined properties during fetal development that are characteristic of common and rare human genetic diseases.
“We were able to identify cellular transitions and the genes that appear to push toward these transitions, making a map of developmental states and showing that tubular cells are derived from a separate population than podocytes, as has been shown to be the case in mice. We found some paths that had been hypothesized in humans but not clearly shown involving parietal epithelial cells, proximal tubule cells, and podocytes,” said first author Jonathan Levinsohn, MD, PhD, of Children’s Hospital of Philadelphia. “Also, by examining genes involved in rare cases of kidney malformations, we identified cell states that appear to be more likely affected. We also examined heritability of adult kidney traits and found evidence that particular fetal cell states may subtly contribute to kidney health later in life.”

Health happens where people work, live, play and worship, says Prof. Stacey Snelling, chair of the Department of Health Studies in American University’s College of Arts and Sciences. And that’s where the Healthy Schools, Healthy Communities Lab engages children, adults and older adults to tackle health inequities. Snelling received a three-year grant of $2.8 million from Novo Nordisk Inc. for health education and to grow the number of Black farmers producing locally grown fruit and vegetables. The goal is to improve local ...
BOSTON – Ready or not, patients with cancer are increasingly likely to find themselves interacting with artificial intelligence technologies to schedule appointments, monitor their health, learn about their disease and its treatment, find support, and more. In a new paper in JCO Oncology Practice, bioethics researchers at Dana-Farber Cancer Institute call on medical societies, government leaders, clinicians, and researchers to work together to ensure AI-driven healthcare preserves patient autonomy and respects human dignity.
The authors note that while AI has immense potential for expanding access to cancer care and improving the ...
Researchers at Weill Cornell Medicine have led a phase 1 trial of a new drug that delivers potent radiation therapy directly and specifically to cancer cells in patients with advanced prostate cancer. The clinical trial showed that the “radiopharmaceutical” was well tolerated and demonstrated promising antitumor activity, according to a new study published on Nov. 2 in the Journal of Clinical Oncology.
The radiopharmaceutical 225AC-J591 was administered in a single injection and consists of two parts: an antibody that helps find the cancer cells is linked to a molecule that delivers a deadly dose of radiation. Specifically, an antibody named J591 that ...
MINNEAPOLIS/ST. PAUL (11/03/2023) — Research led by the University of Minnesota Medical School identified a new pathway to combat cardiovascular disease. The study was recently published in Nature Cardiovascular Research.

Ever since the discovery of the Higgs boson in 2012, physicists have wanted to build new particle colliders to better understand the properties of that elusive particle and probe elementary particle physics at ever-higher energy scales.
The trick is, doing so takes energy – a lot of it. A typical collider takes hundreds of megawatts – the equivalent of tens of millions of modern lightbulbs – to operate. That's to say nothing of the energy it takes to build the devices, and it all adds ...
November 3, TORONTO — Scientists at the Ontario Institute for Cancer Research (OICR) have uncovered one way tobacco smoking causes cancer and makes it harder to treat by undermining the body’s anti-cancer safeguards.
Their new study, published today in Science Advances, links tobacco smoking to harmful changes in DNA called ‘stop-gain mutations’ that tell the body to stop making certain proteins before they are fully formed.
They found that these stop-gain mutations were especially prevalent in genes known as ‘tumour-suppressors’, ...
