One of the favored options for generating complex transgenic laboratory mice is through in-house breeding and management strategies. One consideration in the management of these colonies is how the animals' environment may affect reproductive success. Several aspects of the microenvironment can be controlled or manipulated, including cage type, bedding, enrichment, diet, and temperature and humidity.

- Scientists have found it really tough to see blood flow in older brains because of their thicker skulls, which makes traditional imaging hard to use.
- They are using a new method called functional ultrasound (fUS) that lets them see blood flow in real-time and clearly.
- In this study, researchers replaced the skull of older mice with a special window to get better images and discovered important details about blood vessels in the brain for ongoing research on aging.
Introduction: Cerebrovascular pathologies contribute to cognitive decline during aging, leading to vascular cognitive impairment and dementia (VCID). Levels of circulating insulin-like growth factor 1 (IGF-1), a vasoprotective hormone, decrease during aging. Decreased circulating IGF-1 in animal models leads to the development of VCID-like symptoms, but the cellular mechanisms underlying IGF-1-deficiency associated pathologies in the aged cerebrovasculature remain poorly understood.
