Evaluation of the therapeutic effect of very small stem cells from peripheral blood on the treatment of Premature Ovarian Failure: A pilot study

Objective: Premature ovary failure (POF) is a severe health condition with multiple negative outcomes, which deteriorate a patient's life.The current study aimed to evaluate the therapeutic effect of mesenchymal stem cells (MSCs) derived from peripheral blood in the treatment of women with the POF background.Methods: The current study was a pilot study carriedout on women younger than 40 with premature ovarian failure.Study participants underwent 4-months cell therapy using Mesenchymal stem cells extracted from peripheral bloods.Serum level of Follicle-stimulating hormone (FSH), Estradiol (E2), Anti-mullerian hormone (AMH), and Antral follicle count (AFC) were the main investigated outcomes that were assessed at baseline, month two and month four of the very small stem cell intervention.Results: Average serum level of FSH was 45.0 (12.1) mIU/mL at baseline and continually decreased during the study and reached 33.2 (12.4) mIU/mL in the fourth month.The average AMH level was 0.10 ng/mL prior to the intervention and increased to 0.13 ng/mL in the 2nd month and 0.15 ng/mL in the fourth month.The level E2 was 85.7 (23.6) pg/ml on average at baseline, while the average E2 reduced to 77.2 (25.6) pg/ml in the fourth month.Average number of AFC was 2.0 (0.8) at baseline.We observed a gradual increase in the second month (Mean AFC=2.2) and after four months it increased to 3.1 (1.8) as the highest menstrual restoration and pregnancy was observed in 10% of our study participants.Conclusions: MSCs could significantly improve hormone secretion in women with POF.Implantation of MSCs in women with POF background was associated with an increase in AMH and AFC, while it downed the serum level of E2 and FSH.MSCs could also lead to menstrual restoration and pregnancy in women with POF.
