Another pluripotent stem cells from skin cells

Instead of a viral vector, scientists used plasmids to inject "embryonic" genes into fibroblasts, with the help of which they managed to successfully transform ordinary skin cells into pluripotent stem cells.

Erythropoietin against infarction

A single intravenous injection of the hormone erythropoietin (EPO) immediately after inarct can minimize the process of apoptosis and thereby limit damage to cardiac tissues.

A safe method for early diagnosis of Down syndrome and other trisomies

The new diagnostic method is based on determining the number of fragments of fetal chromosomes in the mother's blood. In addition to Down syndrome, researchers were able to accurately identify cases of trisomy of the 18th chromosome (Edwards syndrome) and trisomy of the 13th chromosome (Patau syndrome).

Excess calories disrupts the brain

Excessive intake of calories into the body, even if it does not lead to an increase in body weight, disrupts the work of the hypothalamus, which plays a major role in maintaining energy balance.

Progenitor cells forming adipose tissue have been identified

One of the tested populations, whose cells express the CD24 cell surface marker, formed fat deposits in experimental animals. This population usually makes up no more than 0.08% of all non-fat cells contained in normal adipose tissue.

A new achievement in bacterial training

The authors plan to "train" bacteria to recognize chemical processes associated with danger in the body. Such a "live indicator" can be configured so that the synthesis of a signal protein begins in response to the appearance in the body of molecules characteristic of the undesirable effects of drugs or indicating the presence of malignant tumors.

The mechanism providing metastasis of melanoma is identified

Deciphering the mechanism of triggering a signaling cascade that increases the mobility and invasiveness of tumor cells opens up another potential molecular target for the treatment of melanoma, and possibly other types of cancer, including breast and stomach cancer.

The immune system sometimes plays on the side of the tumor

Until now, experts believed that the complement system ensures the elimination of tumor cells. However, in some cases, depending on the type of tumor and the specific environment in which it develops, the complement system, on the contrary, stimulates the growth of tumors.

A new approach to the gene therapy of type 1 diabetes

Some of the endocrine cells of the gastrointestinal tract are potentially ideal target cells for gene therapy of diabetes, and the introduction of the insulin gene through the intestine is absolutely non-invasive and avoids many disadvantages of existing approaches.

The production of olfactory receptors is a step towards an "artificial" nose

MTI scientists have developed a method for mass production of olfactory receptors in the laboratory. This achievement is not only a step towards the creation of an "artificial nose" that can help solve many problems, but also brings scientists closer to deciphering the mechanisms of smell.
