Induced Pluripotent Stem Cells (iPS)

Researchers at Washington University have tested an experimental new treatment for rheumatoid arthritis in mice. The team implanted stem cells that have been reprogrammed to secrete anti-inflammatory drugs only when they sense inflammation.

Researchers have made a striking breakthrough in lab-grown mini organs. Using induced pluriopotent stem cells, the team induced brain organoids to develop rudimentary eye structures that can sense light and send signals to the rest of the brain.

Researchers have found a way to maintain insulin levels in diabetic mice by growing and implanting new beta cells that produce the hormone. These cells are housed inside a tiny device that protects them from the immune system, like a shark cage.

Researchers at Salk Institute have uncovered a mechanism by which stem cells can help regenerate muscles. The discovery could provide a new drug target for repairing muscles after injury or rebuilding muscle mass lost during the normal aging process.

Scientists have created the first-ever functional miniature human hearts in the lab. Grown from stem cells, these heart “organoids” are made up of all primary heart cell types, and could help build better models for treating disease.

Imagine needing a liver transplant and, instead of waiting for a donor, a new one could just be grown from your own skin cells. In a big step towards this, mini human livers grown from stem cells have been successfully transplanted into rats.

Stanford scientists may have found a way to essentially return older cells to a more youthful state. The adult cells are treated with a mix of proteins from early embryonic development, which removes many of the molecular signs of aging.

One emerging treatment for diabetes involves converting stem cells into beta cells that secrete insulin. Now scientists have developed a more efficient method, and implanting these cells in diabetic mice functionally cured them of the disease.

Organ transplants are invasive and donors hard to find. Treating kidney disease with stem cells is an option, and now researchers have isolated and studied kidney stem cells from urine samples, which could be a much easier way to collect them.

New research suggests Parkinson's may be present in the brain right from birth, as malfunctioning neurons are always there. Thankfully, a drug that’s already on the market could help prevent the disease from taking hold if caught early enough.

An incredible new study has for the first time found a way to transform skin cells into all three of the stem cell types that make up an early-stage embryo. This extraordinary discovery points a way toward creating an embryo without the need for an egg or sperm.

We have known for well over a century that exposure to certain environmental agents can result in DNA mutations that ultimately cause cancer. Now a team of UK scientists has developed a way to identify specific mutational signatures in tumors that can be linked to certain carcinogens.​
