Petri dishes have become a symbol of scientific discovery, playing an essential role in experiments and innovations across various scientific disciplines. Understanding their history...
University of Wurzburg recently announced successfully producing human tissues from stem cells with a complexity similar to that of normal tissue. These complex 3-dimensional tumor and brain organoids which were developed in a Petri dish feature functional blood vessels, connective tissue, and in the case of brain tissues also brain-specific immune cells.
The study was published in the journal Scientific Reports in which the scientists claim that the miniature organs produced are far superior to previous structures.
The following is an excerpt of a Longevity Technology interview with co-author and anatomist Dr. Philipp Worsdorfer.
Scientists have discovered how to grow immortal skin cells in a petri dish a discovery that could revolutionize cosmetic surgery. The cells are classed as immortal because they continue to grow and divide no matter how many times they are transferred from culture to culture. Animal tests have been promising up-to-now with the cells growing into multiple layers like normal skin, and superficial wounds have healed well.
Human clinical trials notoriously go through many lengthy processes that could take decades, long enough for the study subjects to be monitored and live out the rest of their lives. Canine trials, however, do not take as long due to their shorter lifespans, meaning that before there is an anti-aging drug for humans, we are more likely to have one for dogs, and let’s face it that anti-aging doggie supplement is likely to be in high demand as it tugs on our heartstrings.
A molecular mechanism has been discovered by researchers from the University of Pittsburgh School of Medicine by which excessive intake of dietary protein could increase the risk of developing atherosclerosis, their findings have been published in Nature Metabolism.

The ultraviolet nail polish drying devices used to cure gel manicures may pose more of a public health concern than previously thought. Researchers at the University of California San Diego studied these ultraviolet (UV) light-emitting devices and found that their use leads to cell death and cancer-causing mutations in human cells.
A newly published study from York University sheds light on the biological underpinnings of gender differences in obesity-related disease, with researchers observing striking differences in the cells that build blood vessels in the fatty tissue of male versus female mice.
Men are more likely than women to develop conditions associated with obesity such as cardiovascular disease, insulin resistance, and diabetes, says York Professor Tara Haas with the Faculty of Health's School of Kinesiology and Health Science.
According to a new release, scientists have developed a research method that allows for a much more detailed examination of the brain processes involved in some neurological and mental disorders. This is achieved by growing human cortical organoids in culture and inserting them into developing rodent brains to see how they integrate and function over time. The study, funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, appears in the journal Nature.
It was a medical mystery: When University of Pittsburgh School of Medicine scientists induced a particular genetic mutation in mouse eggs, the resulting embryos would all die in the womb within a week.
And yet, people with the same troublesome gene are thriving.
Chemotherapy successfully treats many forms of cancer, but the side effects can wreak havoc on the rest of the body. Delivering drugs directly to cancer cells could help reduce these unpleasant symptoms. Now, in a proof-of-concept study, researchers reporting in ACS Nano made fish-shaped microrobots that are guided with magnets to cancer cells, where a pH change triggers them to open their mouths and release their chemotherapy cargo.
