Researchers develop better ways to culture living heart cells on the International Space Station

Posted by in categories: biotech/medical, cryonics, life extension

As part of preparing for an experiment aboard the International Space Station, researchers explored new ways to culture living heart cells for microgravity research. They found that cryopreservation, a process of storing cells at-80°C, makes it easier to transport these cells to the orbiting lab, providing more flexibility in launch and operations schedules. The process could benefit other biological research in space and on Earth.

The investigation, MVP Cell-03, cultured heart precursor on the station to study how microgravity affects the number of cells produced and how many of them survive. These precursor cells have potential for use in disease modeling, drug development, and , such as using cultured to replenish those damaged or lost due to cardiac disease.

Previous studies suggest that culturing such cells in simulated microgravity increases the efficiency of their production. But using live cell cultures in space presents some unique challenges. The MVP Cell-03 experiment, for example, must be conducted within a specific timeframe, when the cells are at just the right stage. Flight changes and crew availability could lead to delays that affect the research.

New method preserves viable fruit fly embryos in liquid nitrogen

Posted by in categories: biological, cryonics, food, genetics, life extension

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species. However, until now, the practical cryopreservation of the fruit fly (Drosophila melanogaster)—which is crucial to genetics research and critical to scientific breakthroughs benefiting human health—has not been available.

“To keep alive the ever-increasing number of with unique genotypes that aid in these breakthroughs, some 160000 different flies, laboratories and stock centers engage in the costly and frequent transfer of adults to fresh food, risking contamination and ,” said Li Zhan, a postdoctoral associate with the University of Minnesota College of Science and Engineering and the Center for Advanced Technologies for the Preservation of Biological Systems (ATP-Bio).

In new research published in Nature Communications, a University of Minnesota team has developed a first-of-its-kind method that cryopreserves fruit fly embryos so they can be successfully recovered and developed into adult insects. This method optimizes embryo permeabilization and age, cryoprotectant agent composition, different phases of nitrogen (liquid vs. slush), and post-cryopreservation embryo culture methods.

Scientists Are Planning to Build Noah’s Ark on the Moon

Posted by in categories: asteroid/comet impacts, cryonics, existential risks, life extension

Earth is destined for disaster. This is a good insurance policy.


In 2013, a cataclysmic meteor the size of a six-story building broke apart above Chelyabinsk, Russia, and the resulting blast was stronger than a nuclear explosion. In 2068, astronomers believe a potentially hazardous “God of Chaos” asteroid could slam into Earth. Both events suggest humans—and every other animal and plant on Earth—are much more susceptible to total annihilation than we think.

Scientists produce the first in-vitro embryos from vitrified African lion oocytes

Posted by in categories: biological, cryonics, existential risks, life extension

A team of scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) inGermany, Givskud Zoo–Zootopia in Denmark and the University of Milan in Italy succeeded in producing the very first African lionin-vitroembryos after the vitrification of immature oocytes. For this specific method of cryopreservation, oocytes are collected directly after an animal is castrated or deceased and immediately frozen at-196°C in liquid nitrogen. This technique allows the storage of oocytes of valuable animals for an unlimited time, so that they can be used to produce offspring with the help of assisted reproduction techniques. The aim is to further improve and apply these methods to save highly endangered species such as the Asiatic lion from extinction. The current research on African lions as a model species is an important step in this direction. The results are reported in the scientific journal Cryobiology.

Lion oocytes are presumed to be very sensitive to chilling due to their high lipid content, resulting in poor revival following slow cooling. Vitrification can circumvent this problem, as the cells are frozen at ultra-fast speeds in solutions with a very high concentration of cryoprotective agents. This method prevents the formation of ice crystals in the cells, which could destroy them, and enables them to remain intact for an unlimited time to allow their use later on.

For the present research, the scientists collected oocytes from four African lionesses from Givskud Zoo—Zootopia after the animals had been euthanised for the purpose of population management. Half of the oocytes (60) were vitrified instantly. After six days of storage in liquid nitrogen, the vitrified oocytes were thawed and subjected toin-vitromaturation in an incubator at 39°C for a total of 32–34 hours. The other half (59) were used as control group and directly subjected toin-vitromaturation without a step of vitrification. Mature oocytes of both groups were then fertilized with frozen-thawed sperm from African lion males. “We could demonstrate a high proportion of surviving and matured oocytes in the group of vitrified oocytes. Almost 50% of them had matured, a proportion similar to that in the control group,” says Jennifer Zahmel, scientist at the Department of Reproduction Biology at the Leibniz-IZW.
