Under the investigated conditions, only subcutaneous cell injection allowed for reproducible engraftment of MPC LUC/GZ cells in NMRI-nude mice, whereas intravenous cell injection led to inefficient engraftment and non-reproducible metastatic scatter. Hands-off healing. Female mice are injected interperitoneally (IP) with pregnant mare serum (PMS) between 1:00 and 4:00 PM of Day 1. Devices were loaded with 1200 rat islets in culture medium or in alginate. Xenografting is accomplished by subcutaneous injection of tumor cell line cells (typically 1,000,000 cells per animal, single flank injection in 50% Matrigel solution). Although widely used as a means of administering substances, particularly injectable anaesthetics, this is an inherently unreliable technique, since inadvertent injection of some material into the gut, abdominal fat and subcutaneous tissues is a relatively frequent occurrence. Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia. This technique, however, has limitations in that it does not take into account the impact of the microenvironment of the mammary gland on cancer growth. ii. 8 Immunization Animals received two injections (two weeks apart) of aluminum hydroxide, squalene, aluminum hydroxide and squalene or PBS.
