Multicellular spheroids which promote cell-cell and cell-matrix interactions were prepared in culture with mouse B16 melanoma cells (pigmented or non pigmented) alone or mixed with mouse 3T3 fibroblasts. Their volume and proliferation or necrosis rate were evaluated. As measured by dot blot immunoassay, laminin was mainly produced by fibroblasts rather than by melanoma cells. High levels of laminin B1 chain mRNA were detected only in spheroids composed of 3T3 fibroblasts. The levels of 67 kD laminin binding protein mRNA were high in all cell populations studied here.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012333 RNA, Messenger RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
