Biobridge Foundation, Regenerative Medicine News
Androgenetic alopecia (AGA) is a common chronic hair loss disorder. It affects up to 80% Caucasian men and 40% women. Although AGA is highly prevalent, approved therapeutic options are limited, with potential adverse effects. Platelet-rich plasma (PRP) is an emerging treatment for AGA. The regenerative potential of PRP depends on the growth factors (GF) released by platelets. GF appear to act in the bulge area, activating the proliferative phase of the hair. Therefore, PRP is a potential treatment of AGA.
Although there were several systemic reviews and meta-analyses on the application of PRP in the treatment of AGA1,2 , the work presented below, stands out because it focuses on female patients.
This newsletter contains recent publications and information on research and treatments using PRP or BMC concentrate.

Latest publication: Study – Female Androgenetic Alopecia
Platelet-Rich Plasma in Female Androgenetic Alopecia: A Comprehensive Systematic Review and Meta-Analysis
In this work, Zhou et al.3 summarize different treatment regimes in female androgenetic alopecia (AGA), and quantitively analyze the efficacy of PRP in this disease.
They evaluated 636 studies and 12 trials from six databases (MEDLINE, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, LILACS, and CNKI ). Meta-analysis was conducted with enrolled observational studies and randomized controlled trials separately.
A total of 42 studies (including 6 studies using Regen Lab technology4-9) including 776 female participants, covering 16 randomized controlled trials and 26 observational trials, were included for these systematic review and meta-analysis . PRP showed positive efficacy in treating female AGA in hair density compared to the control groups with odds ratio (OR) 1.61 [95% CI 0.52–2.70] and compared to baseline with OR 1.11 [95% CI 0.86–1.37].
This work demonstrated an effective response and safety for the application of PRP in the treatment of female AGA. Especially for those patients with negative response to the topical use of minoxidil, PRP offers an alternative treatment option.
The authors only used hair density as an endpoint to perform meta-analysis for the diversity of endpoint settings among the enrolled studies, while hair density is the most used one. This result is in accordance with previous systemic review.
Taken together, these results confirm the efficacy of PRP in the treatment of female AGA.

New Medical Devices Regulation
The new Medical Devices Regulation (2017/745/EU), applicable since May 2021 in EU, will replace the existing Medical Devices Directives (93/42/EEC).
This regulation provides a framework for the manufacture, modification, and use of devices when equivalent devices are not commercially available (Article 5 of the Medical Device Regulation). In these situations, health care facilities will be required to have appropriate quality management systems in place, to document the manufacturing process, design, and performance data of the devices, including their intended purpose, and to monitor experience gained from the clinical use of these devices.
In the case of marketed devices, the manufacturer is responsible for the quality and safety of the product.
Regen Lab actively pursues patent protection and regulatory approval of its products so that physicians have peace of mind that they can offer continuous, consistent, safe and effective treatment for their patients without the fear of being restricted in their practice.
