Hair follicle stem cells (green) mobilize and expand (white) to help repair the skin’s barrier by differentiating into epidermal lineages (red). Credit: Robin Chemers Neustein Laboratory of Mammalian Cell Biology and Development at The Rockefeller UniversityWhen a child falls off her bike and scrapes her knee, skin stem cells rush to the rescue, growing new epidermis to cover the wound. However, only a portion of these stem cells, which eventually repair the damage, are typically assigned the task of replenishing the…

DOI: 10.1057/s41599-024-02797-w An Institute for Systems Biology (ISB)-led study has unveiled important insights and actionable protocols into providing equitable STEM (Science, Technology, Engineering, and Mathematics) experiences for high school students from historically marginalized communities.…

Scientists say they are closer than ever to reviving the woolly mammoth (via The Washington Post). Colossal Biosciences has been working on its project to revive the mammoth. The company shared its hopes to resurrect the mammoth within four years back at the start of 2023, and now it has created important stem cells that are vital for the project to work as planned.Being closer than ever to reviving a long-extinct species does not mean there aren’t still tons of steps to complete. In fact, the creation of these…

Colossal Biosciences, which calls itself “the world’s first de-extinction company,” has created stem cells it thinks will hasten the company’s marquee goal of resurrecting the woolly mammoth. The team’s research describing the accomplishment will be hosted on the preprint server bioRxiv.What Drew John Boyega Back Into Sci-Fi? | io9 InterviewThe cells are induced pluripotent stem cells (iPSC), a type of cell that can be reprogrammed to develop into any other type of cell. The cells are especially useful in bioengineering,…

Research into stem cells has paid off as 68-year-old Paul Edmonds remains effectively cured of both HIV and leukemia following treatment that included a breakthrough stem cell transplant in 2019. Now, five years after the treatment, Edmonds continues to live his life free of HIV and leukemia.This makes Edmonds one of only five people in the world who have achieved full remission of HIV. Further, his 31 years of living with the virus also means he had it the longest out of the five in remission. It’s a striking…

The United States will rekindle the US-India Alliance for Women’s Economic Empowerment to empower women and girls in India to pursue science, technology, engineering and mathematics (STEM) and foster gender-based inclusion through securing resources for women’s STEM employment and entrepreneurship from public and private sectors, Patricia A Lacina, deputy chief of mission, US embassy in India said on Tuesday.“The US Department of State, together with USAID (United States Agency for International Development), is pleased…

Researchers have identified growth regulators that trigger the proliferation of dormant leukemic stem cells in a specific type of acute myeloid leukemia, suggesting a possible approach to prevent relapse by using repurposed drugs. Credit: SciTechDaily.comThe discovery of two growth regulators involved in acute myeloid leukemia relapse offers hope for targeted therapies to prevent recurrence, emphasizing the need for further research to extend these findings to other leukemia subtypes.The mystery of why myeloid leukemias…
