“Our research seeks to illuminate previously often-overlooked ethical dilemmas and legal complexities that arise at the intersection of advanced organoid research and the use of fetal tissue, which is predominantly obtained through elective abortions,” said Tsutomu Sawai, an associate professor a...
Chinese scientists have found a new way to use cells found in human urine (尿液)that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells...
Primary cells—cells isolated directly from tissue—are prized for their abilities to better mimicin vivophysiological metabolism and behavior than cell lines derived from tumors or immortalized cells. Yet at the same time they tend to be more finicky to grow. Primary cells are mo...

texture, according to theSmithsonian blog. For children, doctors sometimes fashion a new ear from the stiffer cartilage surrounding ribs, but it's a big operation. Spector said the end result seldom looks completely natural. Hence the quest to use a patient's own cells to grow a replacement ...
To build organized tissues in the lab, scientists use scaffolds to provide a surface for cells to attach based on a predetermined rigid shape. For example, an artificial kidney needs a structure, or scaffold, of a certain shape for kidney cells to grow on. Indeed, this strategy helps the ...
As good as an antibiotic approach might sound, it’s only a short-term solution. Long-term use of antibiotics in a culture can cause various problems. For one thing, antibiotics can eventually impact the biology of the cells. “Studies have shown that antibiotics may induce changes in cell ...
to the material that is affected in the disease itself, and different types of studies can be conducted in the laboratory instead of through simulations or on animals. Using stem cells, scientists have grown pieces of tissue, known as brain organoids, measuring about 2 to 3 mm long. These ...
In addition, the atmosphere itself contains ~1022 microbial cells, and determining the ability of atmospheric micro- organisms to grow and form aggregates will be valuable for assessing their influence on climate8. Vegetated coastal habitats are important for carbon sequestration, determined by the ...
stem cells is enhanced. We also discovered the key gene responsible for this change and the molecular signaling pathway," says Lei Xiaohua, a member of the research team.P "Can we use micro-gravity conditions to realize large-scale proliferation of stem cells and tissue engineering construction?
