Genetically modified astronauts

Six rodents participated in the experiment on the ISS – three transgenic mice and three control mice. Rodents with increased pleiotrophin production lost 3% of bone tissue in 91 days, while the spine of ordinary mice lost 41.5% of its mass.

An almost universal vaccine for cancer treatment?

The new treatment method affects a molecule characteristic of 90% of cancer cell types. With its help, scientists hope to create a universal vaccine that will allow the immune system to independently defeat the main types of cancer.

Save on genome sequencing

Genome sequencing is the best tool for predicting "family" diseases; studying the personal genome helps to choose individual therapy more accurately. But for healthy people, gene analysis is practically useless.

Stem cells in the treatment of neurodegenerative diseases (6)

The development of methods for the treatment of multiple sclerosis using stem cells goes in two main directions: the suppression of an autoimmune reaction that destroys the myelin sheaths of nerve fibers and the transplantation of myelin-producing nerve progenitor cells.

Stem cells in the treatment of neurodegenerative diseases (4)

For Parkinson's disease – the second most common neurodegenerative disease – there is only symptomatic treatment. A number of experiments have shown the ability of stem cells to significantly increase the number of preserved dopaminergic neurons.
