Laboratory hair to fight baldness

The juicy bald market arouses envy. Some hope to take advantage of advances in reprogramming cells or growing organoids in the lab to regrow lost hair.

Biologists from several start-ups are currently working on creating new cells capable of re-growth of hair, using recent advances in genetic engineering to tackle the age-old problem of baldness.

Researchers tell us that they are using these techniques to grow human hair cells in the lab and even on animals. Young dNovo sent us a photo of a mouse wearing a beautiful tuft of hair, and the results, according to the company, of a human hair stem cell transplant.

The founder of the startup, Ernesto Logan, is a Stanford-trained biologist. He claims that his company can produce the building blocks of hair follicles by “Reschedule” Genetically normal cells, such as blood or fat cells. Although there is still work to be done, Ernesto Logan hopes that one day this technology will replace The root cause of hair loss.

We are born with a certain supply of healthy hair follicles throughout our lives, but aging, cancer, changing testosterone levels, genetic bad luck and even Covid-19 can all cause existing stem cells to die. Poetry. The disappearance of these stem cells is indicative of our hair.

Transfer of cells from one state to another

Ernesto Logan claims that by altering the patterns of active genes in a cell, it can be converted directly into a hair-forming stem cell. In biology, we “Let’s now estimate that the cells correspond to a ‘condition’ Instead of a fixed identity, he explains, And we can move cells from one state to another.”.

The ability to regenerate hair is just one aspect of broader research aimed at overcoming the symptoms of aging through reprogramming technology. in August , MIT Technology Review reported a secretive company, Altos Labs, that intends to study whether reprogramming could allow individuals to rejuvenate. Another startup, Conception, is trying to extend fertility by converting blood cells into human eggs.

A major scientific breakthrough occurred in the early 2000s, when Japanese researchers found a simple formula for converting any type of tissue into pluripotent stem cells.
