Treatment of Androgenetic Alopecia with Autologous CD200 Positive Cell Suspension

The document discusses a case study where a 22-year-old patient with grade III androgenetic alopecia was treated with a cell suspension of occipital follicular units. The treatment involved the extraction of 25 hair follicles, which were then treated with trypsin to separate the cells. The resulting cell suspension, which contained CD200 positive progenitor cells, was then injected into the patient's scalp. After 8 weeks, the patient showed an increase in hair density of 21 hairs/cm2. The study concluded that this method, which repurposes a traditional method used for vitiligo treatment, could potentially be a viable treatment for androgenetic alopecia. However, further studies are needed to confirm this.
