在Hiro Clinic，我们推荐Natural Pro FUE治疗，该治疗可以治疗口服治疗或注射治疗无效的无毛部位，并且几乎不会留下明显的疤痕。 通过从后脑勺采集发根并剃除该区域的毛发，术后管理更加容易，并且只移植所需的数量，获得自然的效果。它可以使用局部麻醉进行当日手术，以实惠的价格提供逐渐的毛发生长，并且可以在日本安全地进行。
Hair Transplantation and Gene Therapy: Future Possibilities and Research Advances
この記事の概要
Hair transplantation surgery is currently the primary method of treating thinning hair and hair loss, but recent years have seen advances in gene therapy. Gene therapy is a new treatment that works directly on the mechanisms of hair growth and hair loss. This article details the basic concepts of gene therapy, current research advances, and future possibilities.
What is gene therapy?
Basic Concepts
Gene therapy is a method to treat diseases or improve symptoms by correcting genetic abnormalities or introducing specific genes into the body. In the treatment of thinning hair and hair loss, it aims to fundamentally solve the cause of hair loss by targeting genes involved in hair growth.
Gene Therapy Methods
The main types of gene therapy include:
Gene insertion: A healthy gene is introduced into the cell and an abnormal gene is corrected.
Gene replacement: Replacing an abnormal gene with a healthy gene.
Gene repair therapy: Correcting specific parts of the abnormal gene.
The potential of gene therapy to treat thinning hair and hair loss
Targeting hair growth factors
Gene therapy can suppress genes that activate hair growth factors or cause hair loss by targeting the following factors:
FGF (Fibroblast Growth Factor): Plays a role in promoting hair growth.
VEGF (Vascular Endothelial Growth Factor): Increases blood vessels around the hair follicle and promotes nutrition to the hair.
BMP (bone morphogenetic protein): Involved in the growth and maintenance of hair follicles.
Suppression of hair loss genes
Hair loss can be prevented by suppressing the activity of genes that cause hair loss, for example by targeting the gene that produces DHT (dihydrotestosterone), a gene involved in hair loss.
Current Research and Developments
Gene Therapy Experiments
Animal testing
Animal experiments have confirmed the effect of gene therapy on hair growth. For example, in experiments using mouse models, the introduction of FGF and VEGF genes promoted hair growth.
Clinical Trials
Some gene therapies have also begun clinical trials in humans, where safety and efficacy are being evaluated and are an important step towards their future commercialization.
Research into the use of stem cells is also progressing, and technology is being developed to regenerate hair follicles from stem cells, which is expected to make it possible to regenerate hair follicles and generate new hair.
Future Possibilities
Personalized Medicine
Gene therapy will lead to personalized medicine, which provides optimal treatment based on each patient’s genetic information, making treatment more effective and with fewer side effects.
Long-term effects
Unlike conventional treatments, gene therapy is expected to have a long-term effect. Once the gene is corrected, it is possible to prevent hair loss for a long period of time.
Development of new treatments
Advances in gene therapy may lead to the development of completely new treatments in addition to current treatments, which will greatly advance the treatment of thinning hair and hair loss.
Challenges of gene therapy
Ensuring safety
The safety of gene therapy is an important issue. If gene correction is done improperly, there is a risk that it may affect other healthy genes. Therefore, research is being conducted to ensure safety.
Ethical issues
Gene therapy also raises ethical issues: to what extent gene manipulation is permissible and how it should be controlled is a matter of debate.
High medical costs
Gene therapy requires advanced technology, and as such is currently potentially very expensive. In order for it to become more widespread, it is necessary to reduce costs and establish systems such as insurance coverage.
Hiro Clinic recommends Natural Pro FUE treatment, which can be used on hairless areas where oral medication or injection therapy is ineffective, and leaves barely noticeable scars. Hair roots are harvested from the back of the head and partially shaved, making post-operative care easier, and only the required number of hairs are transplanted with a natural finish. It is a same-day procedure using local anesthesia, and provides gentle, gradual hair growth at an affordable price, making it a safe option in Japan.
