Another way to directly convert fibroblasts into neurons

Adding two microRNAs to the usual genetic material of skin cells is enough to turn these cells into fully functional neurons, bypassing the stem cell stage.

Are you afraid of Alzheimer's? Chew grape seeds!

After treatment of mice with an Alzheimer's disease model with polyphenols isolated from grape seeds, the content of the beta-amyloid peptide oligomer in their brains decreased significantly.

Will the treatment of blindness lift Advanced Cell out of the financial pit?

Researchers regard the experiment with blindness as an important milestone. This is also a significant step for Advanced Cell, which is experiencing serious economic difficulties due to disputes about the ethics of using embryonic stem cells.

Editing genomes

The technology of replacing some codons in the genome with others in the future will allow us to create organisms with a genetic code that differs from the existing one and completely new properties.

The second competition for developers of medicines and medical equipment

The Bortnik Foundation announces the PHARMA 2011-2 competition for the development of technologies for the production of medicines, medical equipment and medical devices used in the diagnosis and treatment of socially significant diseases.

Mouse-mouse, here's a tooth for you!

Researchers at the University of Tokyo managed to grow full-fledged teeth with dental bones and connective fibers from mouse stem cells and successfully transplant them into the jaws of animals.

Ependymal cells are the "source of youth" of the brain

The secret of the ability of brain stem cells to turn into neurons lies in the cellular structures formed by ependymal cells that provide stem cells with the necessary support.

Transcriptome-induced phenotype remodeling

Such a difficult name was given to the method of direct reprogramming of cells without the creation of induced pluripotent stem cells and their transformation into target cells and without the use of various growth factors.

If only the human liver…

With the help of capsules with human liver tissue implanted in laboratory mice, it will be possible to study the effects of new drugs on the liver, which was previously impossible due to the different reactions of mice and humans to chemical compounds.

Nanotowars with four letters

According to the decree of the Government of the Russian Federation, nanoindustry goods and services are divided into four categories: "A", "B", "C" and "D".

Cannabinoid receptors protect the brain from aging

The absence of type 1 cannabinoid receptors (CB1) is associated with the rapid development of symptoms of brain degeneration similar to those observed in patients with senile dementia.

Glamorous innovations

The first boutique where you can buy an innovative idea has opened in Russia. The projects were presented to potential business angels by well-known figures of show business.

IPSK: problems of transition age

Induced pluripotent stem cells are one of the newest areas of biology that is rapidly gaining momentum. Like any other new science, it has now entered a difficult "teenage" period.

I just remember that the walls are with wallpaper…

Steroid hormones, the synthesis of which by hippocampal neurons is triggered by large doses of ethanol, are to blame for memory lapses the morning after drinking.

Hands off beta cells!

The introduction of the CCL22 protein gene into the beta cells of the pancreas of mice with a model of diabetes stops the autoimmune reaction and protects the subjects from type 1 diabetes.

Artificial trachea on a plastic frame

First, a Y-shaped base was created from a new plastic-like nanocomposite polymer. Two days later, the patient's stem cells were placed there, where they were grown to tracheal cells ready for transplantation.

Stem cells labeled "extra pure"

For the first time in the half-century history of stem cell research, biologists have isolated the purest population of hematopoietic cells. To catch each such cell, they had to "filter out" about two hundred thousand umbilical cord blood cells.

The mystery of longevity

Why human life expectancy has been increasing rapidly in recent decades: solving the "mystery of longevity" with the help of the hypothesis of "manifested slow aging".

Give birth to healthy children!

According to the new law, couples can use preimplantation genetic diagnostics if, due to hereditary diseases of the parents, there is a high probability of the birth of a seriously ill or dead child, as well as a miscarriage.
