Science Explains The Link Between Stress And Gray Hair

Added: 10.07.2020 23:24 | 5 views | 0 comments

Gray hair is often related to: stress, genetics, chemical hair dyes and hair products, thyroid disorder, vitamin deficiencies, autoimmune disease, smoking. Our hair color is determined by cells called melanocytes, since they produce the pigment melanin. There are melanocyte stem cells living inside the hair follicle, which create new melanocytes. But, as we get older, these ...]

New clues from fruit flies about the critical role of sex hormones in stem cell control

Added: 09.07.2020 14:25 | 27 views | 0 comments

In one of the first studies addressing the role of sex hormones' impact on stem cells in the gut, scientists outline new insights showing how a steroidal sex hormone, ecdysone, drastically alters the way intestinal stem cells behave, ultimately affecting the overarching structure and function of this critical organ.

COPD as a lung stem cell disease

Added: 09.07.2020 4:20 | 8 views | 0 comments

Two stem cell researchers have found an abundance of abnormal stem cells in the lungs of patients who suffer from Chronic Obstructive Pulmonary Disease (COPD), a leading cause of death worldwide. The team, who used single cell cloning of lung stem cells to make their discovery, is now targeting the cells for new therapeutics.

Epigenetics: What the embryo can teach us about cell reprogramming

Added: 07.07.2020 16:20 | 19 views | 0 comments

Cell reprogramming provides an outstanding opportunity for the artificial generation of stem cells for regenerative medicine approaches in the clinic. As current cell reprogramming methods are low in efficiency, researchers around the globe aim to learn lessons from the early embryo which might lead them to a more efficient and faster generation of high-quality, fully reprogrammed stem cells.

Order from noise: How randomness and collective dynamics define a stem cell

Added: 06.07.2020 21:20 | 16 views | 0 comments

Without stem cells, human life would not exist. Due to them, a lump of cells becomes an organ, and a fertilized egg develops into a baby. But what actually makes a stem cell? Are these a stable population of specially gifted cells? Scientists discovered that instead, stem cells might emerge due to the collective behavior of cells within the organs.

Hairy, lab-grown human skin cell model could advance hair loss research

Added: 06.07.2020 1:31 | 10 views | 0 comments

A new, hair-sprouting dollop of human skin created in the lab might one day help prevent hair loss. An article describes the hairy creation as the first hair-baring human skin organoid made with pluripotent stem cells, or the master cells present during early stages of embryonic development that later turn into specific cell types.

First treatment for pain using human stem cells a success

Added: 05.07.2020 20:20 | 8 views | 0 comments

Researchers have used human stem cells to make pain-killing neurons that provide lasting relief in mice, without side effects, in a single treatment. The next step is to perform extensive safety tests in rodents and pigs, and then move to human patients suffering chronic pain within the next five years.
