This new web site provides information to assist research workers in developing their skills in the administration of substances to laboratory animals. Initially we have provided material dealing with rats and mice, since they are the animals most widely used in research. Further material will be added to expand the range of techniques and species.
CIEA NOG mouse, a new immune deficient mouse from Taconic
Numerous "humanized" mouse models have been developed over the past twenty years. Components of the human immune system can be reconstituted in a mouse after transplantation of fetal thymus and liver (thy/liv) or fetal thymus, liver and bone marrow (BLT). These models are technically complex, requiring a source of fetal tissue and sophisticated surgical techniques.
Now, a breakthrough new mouse model permits engraftment of human cells via simple tail vein injection. Just inject hematopoetic stem cells (derived from human cord blood or other sources), and the CIEA NOG mouse® will engraft and differentiate those cells to form a functioning human immune system in a mouse. Never before has it been so easy to work with a mouse with a humanized immune system.
So put away your scalpel and pick up a syringe!
How will you use the CIEA NOG mouse®? This groundbreaking model has been validated for studies in oncology, infectious disease, xenotransplantation of normal human tissue and more.

Animal ordering information
Routine laboratory animal handling has profound effects on their anxiety and stress responses, but little is known about the impact of handling method. We found that picking up mice by the tail induced aversion and high anxiety, whereas use of tunnels or open hand led to voluntary approach, low anxiety and acceptance of physical restraint. Using the latter methods, one can minimize a widespread source of anxiety in laboratory mice.

Facial expression is widely used as a measure of pain in infants; whether nonhuman animals display such pain expressions has never been systematically assessed. We developed the mouse grimace scale (MGS), a standardized behavioral coding system with high accuracy and reliability; assays involving noxious stimuli of moderate duration are accompanied by facial expressions of pain. This measure of spontaneously emitted pain may provide insight into the subjective pain experience of mice.
