Researchers at Kindai University have successfully created the first artificial cell nuclei in living mouse eggs by injecting purified DNA instead of sperm. This groundbreaking study, published in the journal Genes to Cells, demonstrates that it is possible to construct a nucleus that closely resembles a natural one, both morphologically and functionally. The team identified the optimal conditions for the injected DNA to form a nucleosome structure, develop a nuclear membrane, and establish nuclear pore complexes, which are essential for nuclear transport functions. This achievement not only advances the understanding of nuclear construction but also opens avenues for potential applications, such as reviving extinct species and creating artificial life. The research highlights the importance of DNA length and concentration in the successful formation of the artificial nucleus, suggesting that a fertilization-like process can be achieved through precise timing and conditions. The findings represent a significant step forward in synthetic biology and the study of cellular mechanisms.
