With roughly 2,000 giant pandas remaining in the wild, scientists have spent the last several decades looking for new ways to help the iconic black-and-white bears stave off extinction. And now, it seems there may be more hope than ever before.
For the first time, scientists have taken ordinary skin cells from the animal and transformed them into stem cells, the team reports September 20 in Science Advances. Having this type of stem cell, which can be nudged into becoming any kind of cell in the body, could help researchers breed more giant pandas (Ailuropoda melanoleuca) and develop treatments for their diseases.
This result “is really a great breakthrough in the field of giant panda conservation,” says Thomas Hildebrandt, a veterinarian who specializes in wildlife reproduction at the Free University of Berlin and was not affiliated with the research. It “opens up a complete new avenue [to rescue] this magnificent species and icon of conservation,” and may suggest strategies for generating stem cells for other vulnerable and endangered species.
Researchers have already turned both mice and human skin cells, called fibroblasts, into stem cells, specifically pluripotent stem cells. These stem cells “have unlimited proliferation potential and can form any kind of cell, tissue or organ in the body under certain conditions,” says Liu Jing, a stem cell researcher at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences. The catch with creating them is that the process must be tailored to each new species.
To reprogram pandas’ fibroblasts into pluripotent stem cells, the team first put some genes known to reprogram adult cells into the skin cells along with small RNA molecules known to enhance the transition to stem cells. The researchers also had to identify the specific proteins and growth factors that would help turn the panda skin cells to stem cells, as well as ones that would keep them in the pluripotent state.
Having pluripotent cells essentially on demand could allow scientists to create giant panda primordial germ cells, precursors to sperm and egg cells, a feat that’s been done in mice and northern white rhinos. Obtaining these panda sex cells has been difficult because the majority of the living panda population remains under strict protections that forbid typical egg extraction techniques, such as giving pandas medicine to make extra eggs in a cycle or retrieving eggs from ovaries.
Scientists are facing a critical challenge when it comes to preserving the genetic diversity of the dwindling panda population. With too few pandas remaining to reliably source eggs from recently deceased animals, researchers are turning to innovative methods to ensure the survival of this iconic species.
One potential solution lies in the ability to generate sperm and egg cells from pandas in a noninvasive manner. By utilizing techniques that involve turning skin cells into stem cells and then germ cells, scientists hope to create new pandas with added genetic diversity. This approach is particularly crucial considering that there are currently 33 isolated panda populations, 15 of which are on the brink of extinction.
The next step for the research team is to create primordial germ cells from the stem cells, a process that could revolutionize panda reproduction and contribute to the overall health of the population. Beyond aiding in the conservation efforts for pandas, pluripotent stem cells derived from this research hold promise for disease diagnosis and treatment.
Dr. Jing, a key member of the research team, emphasizes the importance of not only expanding the giant panda population but also ensuring its long-term health. The potential implications of this work extend beyond pandas, offering hope for the preservation of other endangered species facing similar challenges.
This breakthrough in stem cell technology is not limited to pandas alone. Scientists have successfully created pluripotent stem cells for a variety of endangered species, including drills, Tasmanian devils, Grevy’s zebras, and Sumatran rhinos. As each new species is added to the library of stem cell research, the possibilities for conservation and genetic diversity preservation continue to expand.
The advancements made by this research team pave the way for future initiatives aimed at safeguarding endangered species and promoting biodiversity. By leveraging cutting-edge technologies and innovative approaches, scientists are making significant strides in the field of conservation biology. With each new discovery, the potential to apply stem cell technology to a wider range of species grows, offering hope for the continued survival of our planet’s most vulnerable inhabitants. If you have ever wondered what life would be like on a remote island, look no further than the tranquil and picturesque island of Kauai in Hawaii. This island, also known as the Garden Isle, is a hidden gem that offers a peaceful escape from the hustle and bustle of everyday life.
Kauai is the oldest and most northern of the Hawaiian Islands, and it is also one of the most stunning. The island is home to lush rainforests, cascading waterfalls, and pristine beaches that stretch for miles. With its laid-back atmosphere and stunning natural beauty, Kauai is the perfect destination for those looking to relax and unwind.
One of the most unique aspects of life on Kauai is its remote location. The island is only accessible by plane or boat, which adds to its secluded and peaceful vibe. This means that residents and visitors alike can enjoy a slower pace of life, far away from the chaos of the mainland.
Living on Kauai also means being surrounded by nature at all times. The island is home to an abundance of wildlife, including colorful birds, playful dolphins, and gentle sea turtles. Residents can spend their days hiking through the lush rainforest, snorkeling in crystal-clear waters, or simply relaxing on the beach and soaking up the sun.
Another perk of living on Kauai is the strong sense of community that exists on the island. With a population of just over 70,000 people, Kauai has a close-knit community where everyone knows each other. Residents often come together for events such as farmers markets, festivals, and beach cleanups, fostering a sense of unity and camaraderie.
Of course, living on a remote island does come with its challenges. Supplies can be limited, and residents may have to travel to the mainland for certain goods and services. Additionally, the cost of living on Kauai can be higher than on the mainland, due to the island’s isolation and the need to import many goods.
Despite these challenges, the beauty and tranquility of life on Kauai make it a truly special place to live. Whether you are looking for a peaceful retreat or a new adventure, the Garden Isle has something to offer everyone. So pack your bags, leave your worries behind, and come experience the magic of life on Kauai. The Rise of Virtual Reality Technology in the Gaming Industry
