ELISA measurement of growth factors in tissue homogenates A small part of frozen tissue (approximately 3x3x3 mm) was homogenized in PBS with protease inhibitor (Complete Mini Protease Inhibitor Cocktail Tablets; Roche, Basel, Switzerland). After 2 min centrifugation with 14 000g at 4°C the supernatant (without topping fat layer) was used for ELISA measurement. FGF-2, PDGF-AA, VEGF-D and CXCL12 were determined with Quantikine ELISAs (R&D Systems; Abingdon, United Kingdom), VEGF-A and ANG1 were measured using DuoSet ELISA Kits (R&D Systems) according to the manufacturer’s instructions. The amounts of the respective factors were calculated in relation to the amount of total protein in the homogenates as measured by a protein quantification assay (BCA Protein Assay Kit; Pierce, Rockford, USA).

Breast cancer tissue was obtained from the middle ring of the tumor in a macroscopically vital looking area of the tumor by the pathologist directly after surgical removal of the tumor. Additionally, tumor adjacent tissue (distance to tumor 1-2 cm) was collected.

Expression of angiogenic, antiangiogenic and lymphangiogenic growth factors and chemokines in primary breast cancer The mRNA expression of angiogenic, antiangiogenic and lymphangiogenic growth factors and chemokines was quantified by Real Time RT-PCR in breast cancer tissues, tumor adjacent tissues and healthy breast tissues and normalized to the mean expression of four different housekeeping genes. Relative expression was calculated with the ΔΔCt method. The horizontal line indicates the median of each group. * p < 0.05, ** p < 0.01 and *** p < 0.001.
