Neurons derived from the cells of a person with fragile X syndrome develop atypically when transplanted into a mouse’s brain, a new study has found. Some of the differences replicate those seen in the brains of people with fragile X syndrome. Researchers have struggled to create mice that accurately model the condition, […]

Fragile X neurons develop atypically in chimeric mice

[Peter Hess | Spectrum News | September 14, 2022] A large mutation that leads to fragile X syndrome in people does not set off the same genetic cascade in mice, a new study shows. The work highlights the limitations of using mice to model the condition and the need to explore other model animals, […]
