Human stem cells become more active in space — and that’s not a good thing

Human stem cells become more active in space — and that’s not a good thing

Human stem cells get worn out and age much faster in space, a new study has found, which is a problem for anyone hoping to take a long trip through our solar system. Scientists used artificial intelligence (AI) to track changes to stem cells delivered by SpaceX resupply missions to the International Space Station (ISS). Up in space, the stem …

In Space, Your Own Stem Cells Can’t Sleep And Then Become Zombies

In Space, Your Own Stem Cells Can’t Sleep And Then Become Zombies

It’s hard being in space. You’re isolated from friends and loved ones, your mitochondria get damaged, you get dumber, and you might just get stranded for months at a time (and get under $1,500 for it). Oh, and according to a study just published, your critically important stem cells become insomniacs, which causes you …

Human stem cells age more rapidly in space, study finds

Human stem cells age more rapidly in space, study finds

While scientists are still working to understand the effects an extended trip to space can have on the human body, research in recent years has suggested that astronauts may experience some pretty dramatic changes on both the physiological and psychological levels. In the latest study led by a team at University of California San Diego, researchers found signs of accelerated …

Space travel may accelerate the aging of stem cells by as much as 10 fold, study says

Space travel may accelerate the aging of stem cells by as much as 10 fold, study says

Traveling to space is brutal on the body. Spaceflight can cause astronauts’ bones to lose density, their brain and eye nerves to swell, and their genes to change expression. Research suggests spending time in space is akin to fast-tracked aging. NASA’s pioneering study of the identical twin astronauts Mark and Scott Kelly tracked signals of aging in both men while …

Stem cells age faster in space, study reveals

Facebook Tweet Email Link Spaceflight makes certain human stem cells age faster, a new study has found, furthering scientists’ understanding of the potential effects of space exploration on the human body. Stem cells are found throughout the body, and they can make more of themselves or turn into other specialized cells — including blood, brain or bone cells — for …

Haematopoietic stem cell number is not solely defined by niche availability

Haematopoietic stem cell number is not solely defined by niche availability

Mice B6.Cg-Gt(ROSA)26Sortm14(CAG-tdTomato)/Hze/J (iTdTomato) (007914), C57BL/6J (CD45.2) (000664) and B6.SJL-Ptprca Pepcb/BoyJ (CD45.1) (002014) mice were purchased from The Jackson Laboratory. Nestin–GFP mice48 were bred in our facility. Cdh5-creER, Cdh2-creER, Cxcl12fl/fl, Kitlfl/fl, Tpo−/− and Tg(Alb-Tpo) mice were provided by R. H. Adams, L. Li, T. Nagasawa, S. J. Morrison, F. J. de Sauvage and W. S. Alexander, respectively. Unless indicated otherwise, 8–10-week-old …

Stem Cell Transplants Without Toxic Chemo or Radiation

Stem Cell Transplants Without Toxic Chemo or Radiation

A Stanford Medicine team has developed a novel antibody-based approach that prepares patients for stem cell transplants without relying on toxic chemotherapy or radiation. Credit: Stock A Phase 1 clinical trial has shown that an antibody developed at Stanford Medicine can prepare patients for stem cell transplantation while avoiding toxic side effects. A phase 1 clinical trial has demonstrated that …

Japan says researchers can make human embryos from stem cells

Japan says researchers can make human embryos from stem cells

Japanese regulators just quietly gave researchers there a historic OK to generate human embryos from stem cells in the lab — no ovaries or testes needed. Scientists in Japan and around the world are quickly working toward making viable human eggs and sperm from stem cells, a process called in vitro gametogenesis, or IVG. Those stem cell-derived sperm and eggs …

Kim Kardashian Stem Cell Treatment Post Draws Ire

Kim Kardashian Stem Cell Treatment Post Draws Ire Kim Kardashian is under fire after promoting an expensive stem cell treatment. In an Aug. 8 Instagram post, Kim talked about traveling to Mexico to receive stem cell therapy to treat “debilitating pain” caused by a shoulder injury from lifting weights two years ago. According to her, she’d “tried everything to find …
