This study found that intraperitoneal administration of umbilical cord-derived mesenchymal stem cells exacerbated endometriosis in cynomolgus monkeys, while intravenous administration showed no significant effect on disease progression.

This study explored whether umbilical cord-derived mesenchymal stem cells (UC-MSCs) could serve as a therapeutic resource for endometriosis in seven cynomolgus monkeys. Five monkeys received UC-MSCs and two received saline, with a sequential dosing design involving intravenous UC-MSC administration for 3 months, followed by combinations of weekly intravenous and monthly intraperitoneal UC-MSCs for 3 months, and then weekly intraperitoneal UC-MSCs for 3 months, using 2 × 10^6 cells/kg for all routes; laparoscopic findings and serum CA-125 levels were assessed using the Revised American Society for Reproductive Medicine classification. Intraperitoneal UC-MSC administration led to exacerbation of endometriosis on laparoscopy, while this was not observed in controls, and intraperitoneal dosing exacerbated disease more than intravenous dosing (p = 0.02). The CA-125 level decreased with intravenous UC-MSCs in all monkeys, but the change was not significant, and the small sample size (five treated vs two controls) is an important limitation. This paper is centrally about endometriosis — it tests how UC-MSC administration route (especially intraperitoneal) affects disease severity in a nonhuman primate model.

Abstract

Purpose: This study aimed to explore whether umbilical cord-derived mesenchymal stem cells (UC-MSCs) could be used as a therapeutic resource for endometriosis. Methods: Of seven cynomolgus monkeys with endometriosis, five were administered UC-MSCs (intervention group) and two were administered saline (control group). First, intravenous US-MSC treatment was administered for three months. Second, weekly intravenous US-MSC administration combined with monthly intraperitoneal US-MSC administration was conducted for 3 months. Finally, weekly intraperitoneal US-MSC administration was conducted for 3 months. The dose of UC-MSCs was set to 2 × 106 cells/kg for all administration routes. Laparoscopic findings and serum cancer antigen 125 (CA125) levels were also evaluated. The Revised American Society for Reproductive Medicine classification was used for laparoscopic evaluation. Results: Laparoscopic findings showed exacerbation of endometriosis after intraperitoneal UC-MSC administration, although no changes were observed in the control group. Intravenous UC-MSC administration decreased the level of CA125 in all monkeys; however, the difference was not significant. Intraperitoneal UC-MSC administration significantly exacerbated endometriosis compared with intravenous administration (p = 0.02). Conclusions: This study revealed that intraperitoneal UC-MSC administration exacerbates endometriosis in a nonhuman primate model of the disease.
