Dec. 18, 2024 — Scientists have generated human stem cell models which contain notochord -- a tissue in the developing embryo that acts like a navigation system, directing cells where to build ...

Jan. 3, 2025 — Biologists have shown that the surfaces of plant leaves are coated with a diverse array of RNA molecules. The finding suggests that the RNA present ...

Cell biology is the discipline of biological sciences that studies the structure, physiology, growth, reproduction and death of cells. Research in cell biology uses microscopic and molecular tools ...

Their collaboration has resulted in engineered cells called ‘synthetic organizers’ that deliver instructions to stem cells, telling them to grow into specific tissues and organs.

These regulators are known as MYB, HDAC2, and FOXA2 and when they were suppressed in colon cancer cells, the cells switched back to a normal-like state, removing the cancer threat without ...

Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily ...

A large-scale single-cell study shows aging happens in specific stages driven by molecular cues, offering targets to modify the aging process and revealing key age and sex-related cellular differences ...

CD4 T helper cells are a type of white blood cell called a lymphocyte that serves an important role in your immune system. These cells help defend the body against infection by directing other "killer ...

The cells were placed on ice and lysed by sonication with a Branson Digital Sonifier 250 and a Sonifier Sound Enclosure by applying three cycles of 30 s of 0.2 J/s sonication and 90 s of rest. The ...

Crude cell extracts were prepared by sonication (pulse on, 3 s; pulse off, 4 s; 10 times). The protein content of the crude extracts was determined using a Bradford assay with BSA as a standard ...
