Model Description

Derived from the Okamoto-Aoki Strain
Males exhibit average systolic blood pressures greater than 200 mmHg by 3-4 months of age
The SHR is generally used for studies in hypertension and cardiovascular research
Based on historical usage, the SHR has outbred nomenclature NTac:SHR. However, genetic testing has shown that this colony is homozygous at all alleles tested (inbred). Taconic maintains the SHR through random breeding in a closed colony.

Origin:

The Spontaneously Hypertensive outbred model was developed by NIH in 1966 from Wistar Kyoto outbred stock from Okamoto, Kyoto School of Medicine. Taconic received stock at F35 from the NIH Animal Genetic Resource in 1972. The rats were derived by embryo transfer in 1984.
