FIG. 9.

Growth of subcutaneous B16 tumors in EIIIA- and EIIIB-null mice. B16 F₀ tumor cells were injected subcutaneously into EIIIA-null or EIIIB-null or heterozygous mice at 8 weeks of age. Tumors were collected after 14 (EIIIA) or 17 (EIIIB) days. Medians (solid horizontal lines) and means (double lines) (EIIIB) are indicated. P values were calculated by the two-tailed Student's t test. Histological sections also showed no visible differences in tumors grown in null and heterozygous animals (data not shown).
