Induced pluripotent stem cells on the way to the clinic

Judging by the speed with which the field of cellular technologies is developing, the clinical application of induced pluripotent cells for the treatment of many diseases, transplantation of tissues and organs, as well as rejuvenation of the body is looming on the horizon.

Two in one: a cure for stress and baldness

The study of the effect on the digestive tract of a drug that blocks the action of one of the "stress hormones" showed an unexpected side effect: astressin-B cured mice from baldness.

The recipe for prolonging life: become a dwarf!

Dwarfism in Laron syndrome is caused by a violation of the synthesis of insulin–like growth factor, an increased concentration of which leads to "diseases of aging" - cancer, diabetes, circulatory disorders. Drugs that suppress the synthesis of IGF exist. Do you want to try it?

Let's wait to be afraid of nanoparticles

Nanotoxicology is developing intensively. Maybe it will take another five years until there are statistics on the impact of nanoparticles on health. In any case, it is impossible to be afraid in advance of what may not be dangerous.

Smart Implants

Thanks to nanotechnology, the possibility of creating "smart" implants that can automatically respond to changes in the body by releasing antibacterial or anti-inflammatory drugs, growth factors, etc. is approaching.

Theories of aging

The mechanisms of aging are combined into a single biochemical pathway

The discovery of the biochemical pathway of aging, linking mechanisms previously considered independent, provides a deeper understanding of the aging process and may show new targets for the prevention of aging and slowing down age-related changes.

Biologists have found problems in pretending cells

Induced pluripotent stem cells retain a genetic memory of their origin. This problem has been solved in mouse iPSCs, but reprogrammed human cells are not yet amenable to attempts to make them forget what they were before.

Genetic instability of human pluripotent cells

Human pluripotent cells, both embryonic and induced, are prone to the accumulation of genetic disorders. Researchers have not been able to determine at what point subchromosomal disorders appear in cells

"Valentines" from a test tube

To understand the mechanism of a rare hereditary heart disease, experts turned skin cells into heart muscle cells, studied the disorders in their work and ... cured the disease. However, so far – the cells have "in vitro".

Personal medicine: the way to the horizon

The ideal variant of personalized medicine, which the authors of the Human Genome project dreamed of 15 years ago, so far works well only in presentations, research projects and grant applications.

Cell reprogramming: the next successes

Methods of creating induced pluripotent stem cells are becoming increasingly safe. What is even more interesting, the process of reprogramming cells can be carried out directly, bypassing the "embryonic" stage.
