Clinical trial shows ability of stem cell-based topical solution to regrow hair
Androgenetic alopecia (AGA) - commonly known as male-pattern baldness (female-pattern baldness in women) -- is a condition caused by genetic, hormonal and environmental factors. It affects an estimated 50 percent of all men and almost as many women older than 50. While it is not a life-threatening condition, AGA can lower a person's self-esteem and psychological well-being. There are a few FDA-approved medications to treat hair loss, but the most effective can have side effects such as loss of libido and erectile dysfunction. Therefore, the search continues for a safer, effective treatment.
Adipose tissue-derived stem cells (ADSCs) secrete several growth hormones that help cells develop and proliferate. According to laboratory and experimental studies, growth factors such as hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF) and platelet-derived growth factor (PDGF) increase the size of the hair follicle during hair development.
"Recent studies have shown that ADSCs promote hair growth in both men and women with alopecia. However, no randomized, placebo-controlled trial in humans has explored the effects and safety of ADSC constituent extract (ADSC-CE) in AGA. We aimed to assess the efficacy and tolerability of ADSC-CE in middle-aged patients with AGA in our study, hypothesizing that it is an effective and safe treatment agent," said Sang Yeoup Lee, M.D., Ph.D., of the Family Medicine Clinic and Research Institute of Convergence of Biomedical Science and Technology, Pusan National University Yangsan Hospital in South Korea. He led the group of researchers, which also included colleagues from Pusan National University School of Medicine, Pusan National University Yangsan Hospital and T-Stem Co., Ltd.
Journals Clinical Studies and Medicine also have relevant research content, reports in Clinical Studies and Medicine is a peer-reviewed open access journal publishes original research and review article covering all aspects of clinical studies and clinical trials such as the design of clinical studies, the methodology of clinical studies, the management and policy in clinical studies.
The primary aim of journal is to promote the development in clinical studies, short communications and commentaries on the current development of the clinical studies are welcomed.
PiscoMed Publishing started off with a focus in advancing medical research, however with the advancement of all areas of science, technology and medicines, PiscoMed have decided to venture into all areas of research, publishing quality journals that will support the scholarly and professional community across the globe.
