Research summary
’Normal’ paediatric bone marrow is difficult to access as conventional bone marrow aspiration is an invasive procedure which is not performed unless there is clinical indication of abnormality. During cardiac surgery the sternum and rib cage are separated to allow access to the heart. This allows for easy non-invasive access to bone marrow. This study is requesting that a small amount of bone marrow be taken at the site of open wound by the cardiac surgeon. The samples will then we used to create a bone marrow characterisation library listing expression levels of lineage and maturation bio markers using flow cytometry in ‘normal’ paediatric haematopoiesis. This will also be referenced according to age of patient. We currently hold a small library of normal i.e. sibling donors) and larger libraries of abnormal BM characterised by malignancy, inflammatory or immunological response and have gained a great deal of knowledge and understanding from this data. However in certain conditions changes are very subtle but relevant however with only a small cohort of ‘normal’ data it is difficult to identify this with a high level of confidence. There is also very little reference scientifically to ‘normal’ paediatric haematopoiesis or associated aberrancies in non-malignant haematological conditions. Over time we would use the information gathered to aid translational use into diagnostic practice for the benefit of GOSH patients. The Flow Cytometric analysis used for this study is non-genetic testing and will be used solely to identify haematological bone marrow differentiation patterns.
