Objective:
The aim of this study was to investigate if adipose-derived stromal vascular fraction (SVF) treatment has any protective effect on ovarian function in rats with cyclophosphamide (CP) induced ovarian damage.
Design:
This was an experimental animal study.
Participants/Materials, Setting, Methods:
25 mature cycling Wistar-Albino rats were randomized into four groups (n = 5 per group). Rats in groups 1 and 2 received single dose of intraperitoneal (i.p.) 1 mL/kg sodium chloride 0.9% (NaCl). Groups 3 and 4 received single dose of 75 mg/kg i.p. CP. On seventh day, SVF was prepared from adipose tissues of 5 additional rats and groups 1 and 3 received 0.9% NaCl i.p. injections while groups 2 and 4 received 0.2 mL i.p. injections of SVF. On day 21 all rats were euthanized, and serum anti-mullerian hormone (AMH) levels, primordial, primary, secondary, antral, and atretic follicle counts, AMH positive staining follicle counts along with AMH staining intensity of the follicles were evaluated.
Results:
Among two CP induced ovarian damaged groups, SVF treated group showed significantly higher secondary and antral follicle and lower atretic follicle counts, significantly higher mean serum AMH levels, AMH positive antral follicle count and higher intensity of AMH positive follicle scores for primary, secondary, and antral follicles when compared to untreated group. Moreover, group 1 showed no significant difference for all parameters except antral follicle count and AMH positive staining intensity scores for antral follicles when compared to group 4.
Limitations:
This study was conducted on experimental rat model.
Conclusion:
Our study demonstrated a significant protective effect of SVF against CP-induced ovarian damage which reveals the apparent need for further investigation of its precise mechanisms of action as it may provide a new treatment approach for women with premature ovarian failure.
