TLDR The device applies substances directly to body tissues, improving cell transplant and treatment processes.

The document from 11 years ago described a device designed for applying a medium to human tissue or an animal body. The device featured a carrier with a micro-cavity to hold the medium in direct contact with the target area. It could be used on various body parts, including the eye, skin, internal organs, and notably, the scalp for hair follicle regeneration. The device allowed for the transplantation of modified or non-epithelial cells to the ocular surface and other superficial tissues. It also facilitated the controlled, dosable application of substances to improve cell engraftment, proliferation, and differentiation. The device made the transplantation process simpler, faster, and more precise by eliminating the need for cell culture on a lens or other media and enabling control over the location and quantity of cells applied.

community How Does Exosome Therapy Work for Hair Loss?

in Research/Science 5 upvotes 1 year ago

Exosome hair therapy involves injecting stem cell-derived exosomes into the scalp to boost hair follicle regeneration and repair. Exosomes, which are not stem cells but products of them, contain bioactive chemicals and specific growth factors that promote new blood vessel formation, increase cell proliferation, reduce inflammation, and improve tissue repair, all crucial for hair health.

community SCUBE3 and GT20029 could be the closet thing to a cure: Hair Follicle Regeneration and Protection Against DHT

in Research/Science 15 upvotes 1 year ago

SCUBE3 and GT20029 are potential treatments for hair loss, with SCUBE3 stimulating hair growth and GT20029 protecting against DHT. A combined approach using SCUBE3, finasteride or dutasteride, and later GT20029 could provide a comprehensive treatment for androgenetic alopecia.

community Polydopamine Synergizes with Quercetin Nanosystem to Reshape the Perifollicular Microenvironment for Accelerating Hair Regrowth in Androgenetic Alopecia.

in Research/Science 13 upvotes 7 months ago

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

community HairClone: Good info from their site

in Technology 10 upvotes 2 years ago

HairClone aims to rejuvenate miniaturizing hair follicles through follicle banking and cell expansion, with treatments potentially available in the UK by 2022. The process involves extracting, storing, and cloning hair follicles, but full regenerative treatments will take many years to develop.

community Verteporfin and Microneedling

in Treatments 6 months ago

Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.
