B-NDGモデルによる薬物効果の評価
-
研究事例1
Raji-Fluc cells (5 x 10⁵) were injected into B-NDG mice. Antibody X was administered on specified days. (A) Representative in vivo imaging recorded at different time points to monitor tumor progression. (B) Tumor load (as indicated by luciferase activity) kinetic curves post antibody treatment. Early dosing on day 3 in addition to day 10 resulted in robust tumor growth inhibition. In contrast, a single dose at day 10 had little effect.
研究事例2
Humanized B-NDG mice engrafted with human CD34+ HSC were intravenously injected with 5 x 10⁵ Raji-Fluc cells. Five days after Raji-Fluc cells implantation, mice were treated with anti-human PD-1 antibody. (A) Images of tumor load as indicated by luciferase activity. Tumor growth was dramatically inhibited by the human PD-1 antibody at day 7. RC=Raji-Fluc + Control. PDH=Antibody X + Humanized Mice. Naive B-NDG=Untreated Group.
