According to the official website of the Singapore Science and Technology Research Institute on the 21st, the research team of the Institute of Genomics and the Institute of Molecular Cell Biology of the bureau successfully programmed mouse skin cells to obtain blood cells and immune cells, and reconstructed human blood cells from human skin cells. An ultimate goal is an important first step.
One of the main challenges of regenerative medicine is to create new blood and immune cells on demand for patients. Previous researchers have reported that hematopoietic cells are regenerated from mouse skin cells, but the resulting blood cells can only survive for two weeks after being reinfused into mice. The blood cells obtained in the latest study published in Nature Newsletter can remain active in mice for several months and will receive immune cells for immunocompromised patients and other patients who require transfusion therapy. Fresh blood provides a strong guarantee.
In this study, the Singapore team used a “cocktail†approach to mix four factors that convert mouse skin cells into different types of blood cells. They extracted these four factors that maintain normal activity from the blood of the mice, introduced them into the skin cells, artificially reprogrammed the skin cells, and artificially “rewritten†the skin cells to accept the functions of blood cells, making these skin cells directly Has the characteristics of blood cells. Cheng Hui, the first author of the paper, said: "The introduction of these four factors, skin cells and blood cells have almost no difference."
Substitute tea refers to the use of edible plant leaves, flowers, fruits (fruit), roots, etc., using the way of drinking tea (by brewing, boiling, etc.) is a kind of products commonly known.
Substitute tea is divided into leaf, flower, fruit and rhizome; The way of drinking the same as tea is generally composed of one or more items in the two categories of "medicine and food homology" and "can be used for health care" in the food classification stipulated by the Ministry of Health. Tea products made from the roots, stems, leaves or fruits of these plants.
The way of drinking the same as tea, generally by the ministry of Health provisions of food classification of medicine and food homologous category, can be used for health care category, two types of goods in the single or multiple items, with the roots, stems, leaves or fruits of these plants made of tea products.
Substitute tea has certain effect and auxiliary effect for some special groups, belonging to the health conditioning products.
