A small tweak to genes may finally enable us to regrow cartilage

injuries and degeneration may benefit greatly from novel methods for producing cartilage cells. We may finally be able to rebuild cartilage with a simple change to our genes, says the study.today. Takamitsu Maruyama, Daigaku Hasegawa, senior author Wei Hsu, and others reveal two ground-breaking discoveries, including a new understanding of the multifaceted protein -catenin.“The goal of this study,” said Dr. Maruyama of Forsyth Institute, “was to figure out how to regenerate cartilage.

“We know that this molecule is important for cell fate determination, but the mechanism remained open to study,” said Dr. Hsu. The researchers tested what would happen if β-catenin's signaling capacity was only partially compromised, and they discovered that, in that situation, the cells were unable to develop into bone or cartilage. Following these experiments, the researchers came to the conclusion that while Wnt signaling is a factor in bone creation, it is insufficient for“We wanted to know what the factor was for cell fate determination,” said Dr. Maruyama.

“GATA3 binds to the genome sequences required for the reprogramming. GATA3 is a game changer because we can use it to potentially change any somatic cell to become a cartilage-forming cell, similar to using four stem cell factors to generate embryonicControlling cell fate in this way allows researchers to order a cell to become bone, cartilage, or fat, which has huge implications for developing novel treatments for the 1 in 4 people who suffer from cartilage injuries and deterioration.

This groundbreaking study in tissue regeneration has great hope for thousands of patients and presents fresh research directions for experts to investigate.
