Digital embryo gives China a powerful tool to decode the secret of life: scientists
Scientists in
China have developed the world's first 3D model of early
mouse embryos , revealing how life forms in its initial stages at single-cell resolution.
The team said this was a first step towards a deeper understanding of how
diseases such as congenital heart defects develop, while providing insights into organ regeneration and
cancer treatment.
'Early organogenesis is a crucial stage in embryonic development, characterised by extensive cell fate specification to initiate organ formation but also by a high susceptibility to developmental defects,' they wrote in an article published in the peer-reviewed journal Cell last week.
The researchers are from Southeast University in Nanjing, BGI-Research, Fujian Medical University, Sichuan University, the Chinese University of Hong Kong-Shenzhen, Guangzhou Laboratory and the University of Science and Technology of China.
Cell fate specification is the process where cells are guided by molecular signals and
genetic cues towards developing into cell types with different functions.
'A single fertilised egg gives rise to hundreds of cell types that form different tissues and organs. This process is intricately orchestrated. If abnormalities occur, they are likely to lead to diseases,' co-corresponding author Fang Xiaodong, vice-president of BGI-Research, said.

Mammals could regenerate damaged tissue by turning on ‘genetic switch': Chinese team
Chinese scientists say they have restored the damaged outer ear in mice, a mammal that lacks natural regenerative abilities. The researchers said the pathway they identified could be applied to different tissue types and play a significant role in advancing regeneration in vertebrates. The team found that a mouse's failure to regenerate stemmed from an inability to produce sufficient retinoic acid, a derivative of vitamin A that regulates what cell type emerges during a cell's development and tissue repair. 10:16 Rise in Hong Kong infant eczema cases linked to 'excessive' Covid-19 cleaning habits Rise in Hong Kong infant eczema cases linked to 'excessive' Covid-19 cleaning habits This was because mice had lost the DNA 'remote controls' that switch on the gene that encodes an enzyme to convert vitamin A into retinoic acid, they found. By turning on the 'evolutionarily disabled genetic switch', the scientists could reactivate the regeneration of the mouse ear. 'Our study identified a genetic switch involved in the evolution of regeneration,' said the researchers from the National Institute of Biological Sciences in Beijing, the BGI-Research genomics institute and the Shaanxi Key Laboratory of Molecular Biology for Agriculture. They published their research in the peer-reviewed journal Science on Thursday. Some animals possess the power of regeneration. Salamanders, for example, can regrow tissues, organs and limbs, while teleost fish can regenerate nervous tissue and restore function following injuries to their central nervous system. But mammals, including humans, have limited capacity to rejuvenate tissue and organs.

Chinese team deploys new all-in-one research buoy in the South China Sea
Chinese scientists have deployed a buoy-based research platform in the South China Sea that can track both atmospheric and oceanic changes – even in typhoon-force winds. Anchored 3,500 metres (11,400 feet) below the surface, the system is designed for synchronised, multilayered observations spanning 10km (6.2 miles) into the atmosphere and 1km into the ocean, according to the Institute of Oceanology at the Chinese Academy of Sciences in Qingdao, which led the project. The buoy – powered by a hybrid energy system that combines solar, wind, thermal gradient and wave energy sources – can endure extreme marine conditions, including wind speeds over 60 metres per second and wave heights up to 20 metres, the institute said on its website. 'This buoy system features an innovative design with a highly stable surface and mooring structure tailored for deep-sea, high-wave conditions,' Liu Changhua, a senior engineer at the institute, told state broadcaster CCTV on Thursday. 'It's equipped with multiple advanced instruments, including an oceanic quantum lidar and a microwave radiometer, for synchronous observations across the atmosphere, ocean surface and subsurface layers,' he said, adding that the platform had entered a one-year commissioning phase. The buoy was towed to a site in the South China Sea where the water is more than 3,500 metres deep. Photo: Handout Scientists around the world have long used deep-sea buoys to study the ocean. Some, such as the US Ocean Observatories Initiative, are anchored in waters more than 5,000 metres deep and collect valuable data about the ocean and atmosphere.
