| Origin |
Ishibashi rat derived from a cross between a wild male and a Wistar female, with sib mating since 1975 at Azabu University, transferred to Kyoto University in 1978 (IS/Kyo). |
| Strain characteristics |
Malformations of the thoracicolumbar vertebrae leading to kyphoscoliosis with restricted spinal canals and compressed spinal cords. The malformations occur from the 12th. thoracic to the 6th. lumbar vertebrae. Up to 7 vertebrae are affected, and some degree of abnormality occurs in 90% of individuals. The expression levels of Hox10 and Hox11 paralogs, which regulate the formation of lumbar and sacral vertebrae, is extremely low in lumbo-sacral transitional areas of ISR compared with those of normal rats (Seki, 2008). The IS rat shows the low plasma alkaline phosphatase (ALP) activity but there is no relations between the ALP activity and the vertebral anomalies (Maekawa, 1982). (Jun 4, 2009) |
