Viability of tumor cell/fibroblast co-culture with monocytes.

<p>Tumor cells were co-cultured with fibroblasts for 5 days. Freshly isolated naïve monocytes were added to tumor cell/fibroblast co-culture on day 5 and cell viability was measured every 2 days from day 5 to 11. Addition of monocytes did not influence the co-culture´s viability and tumor cell/fibroblast co-cultures with monocytes were as viable as co-cultures without monocytes for each day and tumor cell line. Represented are n = 5 independent experiments. Using an unpaired Student´s <i>t</i> test with unequal variances, no significances were observed between tumor cell/fibroblast co-cultures with and without monocytes.
