Summary
Little is known about the mechanisms that control limb development. We have discovered a new gene which is active in the developing limb of the embryo. This study will provide information on how this new gene controls the development of the limb. Limb defects occur in 1 in 1,000 new-born babies. We believe the absence of our newly discovered gene may be responsible for some of these limb defects. Ultimately, this fundamental knowledge may lead to improved pre-natal diagnosis and better treament ....Little is known about the mechanisms that control limb development.

Summary
There are close to 400 inherited disorders that affect how the skeleton develops, as well as a range of injury and age-related skeletal defects. There is much interest in treating such abnormalities with artificial bone grown outside the body. In order to achieve this aim we must understand all of the processes involved in producing and maintaining bone within the body. We are using both mouse and cell culture models of skeletal development to increase our understanding of these processes.

Summary
Anomalies of the face and limbs are amongst the most common features of human birth defects, and their frequent association suggests that the same genes are involved in governing the development of the limbs and face during embryogenesis. We have used a genomics-based approach to identify genes involved in limb development based on their alteration in a mouse model which develops extra fingers and toes. Defects in this mouse result from changes in Gli3, a gene which is known to be important in b ....Anomalies of the face and limbs are amongst the most common features of human birth defects, and their frequent association suggests that the same genes are involved in governing the development of the limbs and face during embryogenesis. We have used a genomics-based approach to identify genes involved in limb development based on their alteration in a mouse model which develops extra fingers and toes. Defects in this mouse result from changes in Gli3, a gene which is known to be important in both limb and face development. Based on the organs in which our genes of interest are active, we believe that they will also play key roles in embryonic development of the limbs, face and other organs. We now plan to investigate the regulation of a subset of these genes based on analysis in mouse models of limb and face development. In addition, we have chosen to further analyse the function of a completely novel gene we have identified which our preliminary studies suggest may play a role in the normal development of the lip and palate. These studies have the potential to shed light on the processes governing how organs develop, as well as on the molecular basis of common birth defects such as polydactyly (extra fingers and toes) and cleft palate.Read moreRead less
Portable Motor Rehab Device To Improve Arm Movement After Stroke

Summary
One in six people have a stroke at some time in their life. Half the people with upper limb problems after stroke do not recover useful function. New technologies are needed to improve outcomes. This project develops the portable Arm Movement Measurement device, which measures motor control of the arm and hand for clinicians and patients, to improve rehabilitation outcomes, and for researchers to use to measure motor control in clinical studies.
