| Study Title | Exposure to Oral Contraceptives Alters Human Endometrial Stem Cells Culture Media Metabolomics |
| Study Summary | Although the effects of oral contraceptives (OCs) in the endometrium has been well established, its influence in the production and metabolism of endometrial mesenchymal stem cells (EnMSC) remains unclear. Therefore, we analyzed the effect of OCs in the EnMSC secretome by culture media quantitative metabolomics. The EnMSC were collected from menstrual shedding of five donors (OC group, n=3; control, non-OC group, n=2) and cultured for three passages. Cells characterization was performed by flow cytometry, and culture media was collected at the end of each passage for further quantitative metabolomics. The metabolites with higher discriminant power for sample classification were Alanine, PC aa C30:0, c4-OH-Pro, PC aa C32:2, PC ae C32:2, PC ae C40:2, glycine and PC ae C32:1 for the OC group, whereas PC aa C36:6, PC aa C34:4, SM OH C16:1, SM C26:0, PC aa C38:0, serine and PC aa C36:5 were representative of the non-OC group. This panel of metabolites showed 98% of sensitivity in sample classification according with respective groups. Altered concentrations of metabolites may be an effect of OC hormonal properties on EnMSC metabolism. Thus, this metabolomic approach could assist in the management of future stem cell therapies according to patients’ specific responses to hormone treatments. |

Collection:
| Collection ID: | CO001152 |
| Collection Summary: | The endometrial mesenchymal stem cells (EnMSC) were collected from menstrual shedding, isolated and cultured in vitro from donors who used or not oral contraceptives. The EnMSC were grown up until the second passage (P2) and 24h before the end of each passage (P0, P1 and P2) the culture medium was completely replaced for the collection. The samples were centrifuged at 400 × g for 5 minutes, filtered with 0,2 µm filter and stored at -80 ºC until the metabolomics analysis without any extraction method. |
| Sample Type: | Stem cells culture media |
