Scientists studying a flatworm to explore possibility of skin tissue regeneration

By Ratneshwar Thakur

Planaria are fresh water flatworms with an ability to regenerate from almost any number of pieces to form a completely new being

New Delhi: In an ideal world, one would like to live with no deformities. How often you think about being able to re-grow limbs after an amputation or any injury. Imagine being able to regenerate your spinal cord after an accident has left you paralyzed. Nature has many examples of some tiny organisms completely re-growing from their small pieces. Scientists are studying such organisms to learn important lessons in regeneration.

Researchers at the Bengaluru-based Institute for Stem Cell Biology and Regenerative Medicine have reported that deformities in the epidermis (outer skin layer) of an organism called planaria cause the defect in their stem cell function and regeneration. This is significant because epidermal cells are not stem cells.

Planaria are flatworms that live in fresh water and have the ability to regenerate from almost any pieces to form a completely new animal with all functional organ systems. Researchers used planaria as a model organism to understand the mechanism behind its immense regenerative ability.

“Our study has shown how the organization of epidermal cells during planarian regeneration is crucial for regulating stem cell function,” said Dr. Dasaradhi Palakodeti, a scientist at the Bengaluru based Institute, and a co-author of the study published in the journal Development.

Regeneration is often synonymous with stem cells and most of the studies focus on understanding factors essential for ‘stemness’. “Here, for the first time we show how planarian epidermis (non- stem cell) plays a critical role in wound healing and stem cell function,” said Dhiru Bansal, first author of this paper.

However, it is still unclear how the environment surrounding stem cells regulates their function. Researchers believe stem cells are instructed by surrounding cells to make right decisions to proliferate and differentiate for regeneration, to give rise missing tissues. The team is working to understand the role of a specific protein called PABPC2 (cytoplasmic poly A binding protein) in regeneration.

“Our report about a crosstalk between stem cells and epidermis in planaria opens new possibilities that can be addressed in other systems as well,” said Jahnavi Kulkarni, one of the authors of this paper.

The study opens up a new possibility to discover the role of non-stem cells in the skin regeneration. Skin is often well-thought-out for its protective function but this new study highlights other potential roles of the skin.

The research team included Dhiru Bansal, Jahnavi Kulkarni, Kavana Nadahalli, Vairavan Lakshmanan, Srikar Krishna, Vidyanand Sasidharan, Shilpa Dilipkumar, Akash Gulyani, Srikala Raghavan and Dasaradhi Palakodeti (Institute for Stem Cell Biology and Regenerative Medicine, Bangalore); Jini Geo and Renu Pasricha (National Centre for Biological Sciences, Bangalore).

Samsung Galaxy S25 FE may skip chip upgrade, could reuse Exynos 2400e

Samsung’s next Fan Edition smartphone, the Galaxy S25 FE, is likely to feature the same Exynos 2400e processor as last year’s model, according to new leaks.

Samsung appears to be following a conservative route for its upcoming Galaxy S25 FE, with reports suggesting that the smartphone will feature the same Exynos 2400e chipset used in last year’s Galaxy S24 FE. While the tech giant has not officially confirmed the device’s launch, leaks hint that the handset—codenamed R13—is already under development.

According to internal code seen by the media, the Galaxy S25 FE carries the codename siop_r13s_s5e9945, confirming its chipset as Exynos 2400/2400e. This is the same processor seen in the Galaxy S24 FE, indicating that Samsung may skip a processor upgrade this year.

If accurate, this decision places the S25 FE behind newer premium chipsets like the Snapdragon 8 Gen 3, Snapdragon 8 Elite, and MediaTek Dimensity 9400, potentially making the device less powerful in comparison to flagship competitors in 2025.

The Galaxy S25 FE is expected to launch towards the end of Q3 or early Q4 2025, as a more affordable variant of the Galaxy S25 series. Much like its predecessor, it will likely aim to strike a balance between performance and price, appealing to cost-conscious consumers.

Last year’s Galaxy S24 FE, launched in September 2024, came at a price of Rs. 59,999 for the 8GB + 128GB model. It featured a 6.7-inch FHD+ Dynamic AMOLED display with 120Hz refresh rate, 50MP triple rear camera, 10MP selfie camera, 4700mAh battery, and support for Galaxy AI features. If Samsung follows suit, the S25 FE could retain many of these specifications, making only minor hardware or software tweaks.

The report also mentions that the Indian variant of the Galaxy M36 5G may be powered by the Exynos 1380 chipset, the same one used in the Galaxy M35 5G. This suggests Samsung might be keeping things uniform across its mid-range portfolio for 2025.
