Chinese scientists cultivate giant panda stem cells highlighting the potential of induced pluripotent stem cells (iPSCs) in conservation of supporting endangered species.
For the first time, Chinese scientists have successfully cultivated stem cells from giant pandas, a breakthrough that is expected to aid research on panda characteristics and the treatment of panda diseases without causing harm to the animals. The team revealed this on Tuesday, highlighting that the technology also sets the stage for cultivating panda embryos in laboratories, showcasing the potential of induced pluripotent stem cells (iPSCs) in supporting endangered species conservation.
This research was a collaborative effort between scientists from the Guangzhou Institutes of Biomedicine and Health, part of the Chinese Academy of Sciences, and the Chengdu Research Base of Giant Panda Breeding. Their findings were published in Science Advances on Friday. Liu Jing, a co-author of the study, explained that the researchers isolated primary fibroblast cells from both a male and a female giant panda at the Chengdu base. These cells were then reprogrammed using a non-integrating episomal vector method to create giant panda iPSCs (GPiPSCs).

The GPiPSCs demonstrated the ability to differentiate into various cell types, which, according to the study, makes a significant contribution to the resources available for research on giant pandas and potential clinical treatments for their diseases. In the future, these GPiPSCs could be used to develop functional cells and organs for medical treatment, as well as to aid in research on the physiology and pathology of pandas. Additionally, these stem cells could be used to generate panda sperm and eggs for external fertilization.
There is also potential to use GPiPSCs to create giant panda embryos in laboratories, with hopes that one day these embryos could be used in surrogacy programs to produce panda offspring. However, Liu emphasized that this is just the beginning, and there is still much work to be done before this technology can be fully applied to panda reproduction.
China has made significant progress in the protection of giant pandas and their habitats. The wild panda population has grown from about 1,100 in the 1980s to nearly 1,900 today, according to the National Forestry and Grassland Administration. Despite these achievements, challenges remain in conserving the species, particularly due to the fact that female pandas are only fertile for two to three days a year, making successful breeding difficult.
The use of iPSC technology has shown great promise in conserving genetic resources and studying species characteristics for endangered animals, the research team noted.
