Fig. 2From: Effects of single and multiple transplantations of human umbilical cord mesenchymal stem cells on the recovery of ovarian function in the treatment of premature ovarian failure in miceChanges of ovary weight in the once intravenous group and the multiple intravenous groups over 60 days. a, b, c, d In the once intravenous group, ovarian volume of mice was remarkably increased at 7, 14, 21, 28 days post-induction, respectively. n = 5. f, g The multiple intravenous groups showed significantly increased of ovarian volume at 28, 60 days post-induction, respectively. n = 5. e, h The histogram represents the results of statistical analysis of ovarian weight by single and multiple injections, respectively. Organ coefficient = organ weight/weight, n = 5. i Pregnancy rate of POF mice treated with D28 and D60, 1xMSC and 3xMSC. n = 5. j Number of litters per litter of POF treated with 1xMSC. n = 5. k Number of litters per litter of POF treated with 3xMSC. n = 5. *P < 0.05; **P < 0.01. 1xMSC: Single transplantation of hUC-MSC; 3xMSC: Multiple transplantation of hUC-MSCBack to article page
