Cell Line	Route of Transplantation	Age of Mice (weeks)	Time Points of Euthanasia—Days after Cell Transplantation
67NR, 4T1	ort.	6	12, 24, 33, “26”
67NR, 4T1	ort.	52	28 (4, 9, 15, 21) *
67NR, 67NR/0, 67NR/RBP4, 4T1, 4T1/0, 4T1/RBP4	ort.	16	12, 24, 33 **, “26”
67NR/iRFP and 4T1/iRFP	i.v.	16	48 h after cell transplantation

* in brackets: days of blood collection from zygomatic vein; ** 67NR/0 cell line: last time point of euthanasia 43 day; “26”—day of angiogenesis assessment; except for 67NR/0: the day when tumor reached the volume of 1000 mm³, comparable to 67NR and 67NR/RBP4 on day 26; ort.—orthotopically; i.v.—intravenously.
