Fig. 4From: Effects of mesenchymal stem cells on solid tumor metastasis in experimental cancer models: a systematic review and meta-analysisForest plots of meta-analysis for the association between MSC administration and the number tumor metastasis in animal models. A total of 35 comparisons with 489 animals were involved. It found the administration of MSCs increased the number of tumor metastases in experimental cancer models (SMD 1.23, 95% CI 0.43–2.03, I2 = 89%)Back to article page
