Are CD1 mice outbred?
Are CD1 mice outbred?
CD-1 IGS mice are outbred mice derived from a group of outbred Swiss mice developed at the Anti-Cancer Center in Lausanne, Switzerland. They were imported to the US in 1926 and to Charles River in 1959. The CD-1 IGS mice are generally used for genetics, toxicology, pharmacology, and aging research.
Are CD1 mice aggressive?
Male CD1 mice are described as aggressive and territorial24,40, even when housed in sibling groups26. Nevertheless, we observed a relatively low level of aggression in our mice. Our standard housing conditions might therefore have already reduced aggressive behaviors in our study mice.
Are CD 1 mice inbred?
Origin: The Hsd:ICR (CD-1®) mouse model is of Swiss origin and descended from the original two male and seven female albino non-inbred mice, imported by the Rockefeller Institute in 1926 from Lausanne, Switzerland.
What is the difference between inbred and outbred mice?
Genetically, there are two major classes of laboratory mice: inbred and outbred. Inbred mice are genetically homogeneous and there is very little variation or heterogeneity within a pure inbred strain. Outbred mice are bred specifically to maximize genetic diversity and heterozygosity within a population.
Are male mice more aggressive than female mice?
Aggression and sexual behaviour are controlled by the same brain cells in male mice – but not in females. Similar to humans, male mice are, on the whole, more aggressive than females. Because of this, most research into aggression has overlooked females, says Dayu Lin at New York University.
Should male mice live alone?
Current beliefs are that mice are highly social and therefore require social housing in groups to achieve the highest standards of welfare. However, the evidence for this is quite varied and surprisingly limited. In fact, some studies in wild mice suggest that males may prefer not to live with other males.
How long do BALB c mice live?
Survival analysis shows quite higher longevity (median age: about 29 months) in this population when compared with other BALB/c strains.
What does C stand for in mice?
MICE is an acronym for the Meetings, Incentives, Conventions and Exhibitions tourism segment. This is therefore a business-oriented segment, involving obligatory (or non-discretionary) travel.
What is the reproduction cycle of mice?
House Mouse Reproduction Cycle. Mice become sexually mature and able to mate in as little as 5 weeks. Generally, sexual maturity is reached in 5 to 8 weeks. Female mice reproduce up to 8 times in their lifespan, with litters averaging 4 to 7 pups.
What is the species of a laboratory mouse?
Laboratory mouse. The laboratory mouse is a small mammal of the order Rodentia which is bred and used for scientific research. Laboratory mice are usually of the species Mus musculus. They are the most commonly used mammalian research model and are used for research in genetics, psychology, medicine and other scientific disciplines.
What is a CD mouse?
CD-1® Mouse. Nomenclature: Crl:CD1(ICR) Origin: The original group of Swiss mice that served as progenitors of this stock consisted of two male and seven female albino mice derived from a non-inbred stock in the laboratory of Dr. de Coulon, Centre Anticancereux Romand, Lausanne, Switzerland.
Are CD1 mice outbred? CD-1 IGS mice are outbred mice derived from a group of outbred Swiss mice developed at the Anti-Cancer Center in Lausanne, Switzerland.
