Growth and melanogenic activity of B16 melanoma cells cultured with collagen gel.

腫瘍間質と腫瘍細胞との相互作用をin vitroで研究する目的の第一歩として, B16メラノーマ細胞をI型コラーゲン·ゲル上およびゲル内で培養し, その形態, 増殖, チロジナーゼ活性, メラニン産生量について検討し, 通常のプラスチック上で培養した場合と比較した。ゲル内での細胞の形態は, プラスチック上に比べて, より細長く樹枝状となつた。増殖は, ゲル上およびゲル内ともに著明に抑制され, 培養7日後の細胞数は, プラスチック上と比較して, それぞれ約15%と10%となつた。チロジナーゼ活性は, ゲル上およびゲル内では促進され, プラスチック上での場合に比べて約3倍に増加した。それにともなつて, メラニン合成量もゲル上およびゲル内では, 約2倍にまで増加した。したがつて, 今回の結果よりコラーゲンとメラノーマ細胞との相互作用の存在が示唆された。
