To isolate candidate genes concerned with bovine adipocyte differentiation, we have constructed a subtraction cDNA library from a clonal bovine intramuscular preadipocyte (BIP) cell line. We have isolated a set of cDNA clones whose respective mRNA levels are upregulated during the differentiation of BIP cells. The sequence of one subtracted cDNA fragment was highly homologous to that of mouse type XVIII collagen. Northern blot analysis and reverse transcriptase polymerase chain reaction (RT-PCR) showed that collagen XVIII gene expression increased during adipocyte differentiation. The collagen XVIII gene was also highly expressed in fat tissue. Although its function is unclear, these expression patterns indicate that type XVIII collagen may be associated with adipocyte differentiation in cattle.

We have attempted a fine characterization of the angiogenic response induced by multiple myeloma endothelial cells (MMEC) by using the chick embryo chorioallantoic membrane (CAM) assay and by reverse transcriptase-polymerase chain reaction (RT-PCR). Results showed that in the CAM assay MMEC induced an angiogenic response comparable to that of a well-known angiogenic cytokine, namely fibroblast growth factor-2 (FGF-2), while RT-PCR demonstrated that the expression of endostatin mRNA detected in MM treated CAM was significantly lower respect to control CAM. These data suggest that angiogenic switch in MM may involve loss of an endogenous angiogenesis inhibitor, such as endostatin.

In this study we purposed an alternative method to study the angiogenic and invasive potential of neuroblastoma cell suspensions implanted on the chick embryo chorioallantoic membrane (CAM) surface. Neuroblastoma cells were seeded in Matrigel and thereafter the suspension was pipetted onto the CAM surface at day 8 of incubation inside a silicon ring previously loaded onto the CAM surface. Four days after implantation, the silicon ring was removed and the angiogenic and invasive response were studied morphologically at macroscopic and microscopic levels and by reverse transcriptase-polymerase chain reaction (RT-PCR) by using human and chicken primers for several angiogenic cytokines, namely vascular endothelial growth factor-A (VEGF-A), fibroblast growth factor-2 (FGF-2), angiopoietin-1 (ANG-1), hypoxia inducible factor-2alpha (HIF-2alpha), and for an endogenous angiostatic molecule, namely endostatin. Results showed that: (1) Neuroblastoma cells induced an angiogenic response in the CAM assay comparable to that induced by FGF-2; (2) neuroblastoma cells are packed inside Matrigel or are recognizable in the CAM mesenchyme; (3) Angiogenic activity of neuroblastoma cells is associated to an high expression of the transcripts of human VEGF-A, FGF-2, ANG-1 and HIF-2alpha and to a low expression in the transcript of a human endostatin while in the control specimens there is no expression of both angiogenic and angiostatic molecules; and (4) the expression of the transcripts of the same chicken angiogenesis stimulators and inhibitor is unmodified in treated and control specimens. Overall, these data indicate that neuroblastoma cells growth on the chick CAM express characteristics of the human disease. This experimental model could be employed for further research on human tumor progression and anti-angiogenic molecules screening.
