Could MicroRNA Lead The Way In Hair Regrowth?

Introducing MicroRNA 

Identifying a microRNA appearing to modulate the growth of hair is new research in animals. 

Suggesting that microRNA may be the future of hair regrowth treatments is early research. 

Being more effective and less invasive than the current options is the study which appears in the journal Science Advances laying the groundwork for future hair regrowth treatments. 

Commonly associated with getting older is hair loss. As well as environmental and genetic factors, it can also be due to hormonal changes. 

Minoxidil and finasteride are the key treatments for hair loss. Neither is particularly effective and both require frequent reapplication while the Food and Drug Association have approved both treatments. 

Noting the following are the authors of the present study: not for hair loss treatment but serendipity, both are designed. 

Scientists are exploring alternative ways to stimulate hair regrowth as a consequence. To move from a resting state to an active state, research typically focuses on encouraging the hair follicles that are the parts of the skin that grow hair. 

More research has attempted to stimulate hair follicle cells in the laboratory rather than transplanting hair follicles which can be costly and rely on a ready supply of donors. Directly to the area of the scalp that is balding, scientists then apply these cells. 

The hair follicle cells require culturing in the right conditions however research has shown that for this to be effective in stimulating growth.

Involving a 3D sphere are these conditions. 

To shift the hair follicle from a passive to an active state, the hair follicles need to communicate with other cells. Rather than a flat 2D environment, they do this best in a 3D environment. 

3D cultured cells

The researchers began by corroborating this previous research in the present study. Thereby when it comes to treating mice with 2D cultured follicle cells, those 3D cultured follicle cells were in a keratin scaffold and minoxidil, as they did this. 

Transplanted onto the areas of baldness were more effective than either the 2D cultured follicle cells or minoxidil, as with previous research they found that were the 3D cultured follicle cells. Recovering 90% of their hair, after 15 days were the mice that underwent treatment with the 3D cultured follicle cells.  

Here it is noted that the spheroid then mimics the hair microenvironment as also the keratin scaffold acts as an anchor thereby to keep them at the site where they are needed, the 3D cells in a keratin scaffold performed best according to Dr. Ke Cheng, who is the professor in the Department of Molecular Biomedical Sciences at the College of Veterinary Medicine, North Carolina State University, Raleigh, as also the leader of the research. 

They looked at the exosomes, specifically exosomal microRNAs from that microenvironment as they were also interested in how dermal papillae cells regulate the follicle growth process. 

Helping regulate hair follicle activity are dermal papillae. Helping regulate the way genes send communications, microRNAs are molecules. Known as exosomes, they are found in small sacs. 

Looking at the exosomes of both the 2D and 3D cultured cell follicles are the researchers. The microRNA miR-218-5p was encouraging the gene communication that signals hair growth as they noticed it in the 3D cultured cell follicles. 

Whereas inhibiting it stopped the hair follicle from functioning, they confirmed this when they found that increasing the microRNA increased hair follicle activity. 

Future treatments?

The process of transplantation is laborious and costly as the team’s findings are potentially valuable as while the implantation of 3D cultured cell follicles is effective in stimulating hair follicle activity. 

As Dr. Cheng then says, whereas you have to grow, expand, preserve, and inject those cells into the area, cell therapy with the 3D cells could be an effective treatment for baldness. Can be utilised in small molecule-based drugs is MicroRNAs on the other hand. You could create a cream or lotion that has a similar effect with many fewer problems potentially.

To promote hair growth, future studies will focus on using just this microRNA. 

Concluding The Article Here. 

The future does hold promise when it comes to microRNAs. So, you need to know all about it before venturing out to get the treatment. Here is what most of them promise to provide. A head full of hair without any side effects as it varies from hair transplantation. This helps you to grow the hair back in full force. 

While we start researching the various aspects of this therapy, we insist you keep watching the scene closely. There is more to come and so don’t be disheartened. We are here to promote more. Keep watching and believe help is round the corner.
