Alternatives: "a minimal amount of" or "a slight dose of".

Next, we performed an allotransplantation of a marginal dose of WT islets in recipient Erα−/− mice followed by treatment with vehicle or PPT.
A marginal dose of 1,000 islet equivalents (IEQ) of human islets were transplanted under the kidney capsule of recipient mice.
To explore this hypothesis, we used an insulin-deficient model with xenotransplantation of a marginal dose of human islets in nude mice rendered diabetic with streptozotocin.
Here, we used an insulin-deficient mouse model with xenotransplantation of a marginal dose of human islets to test the hypothesis that oestrogens improve islet engraftment during PIT.
In these mice, we performed either sham transplantation or xenotransplantation of a marginal dose of human islets (1,000 IEQ) under the renal capsule (PIT).
