Background: Infants born small for gestational age (SGA) usually show catch-up growth during the first few years of post-natal life. However, some infants remain small and little is known about the factors governing their growth failure. GH and IGF1 receptor mutations only account for a minority of cases. We have now initiated an in vitro assessment of signalling molecules downstream of these receptors and evaluation of cell growth characteristics.<p class="abstext"...

Background: Infants born small for gestational age (SGA) usually show catch up growth within the first few years of life. However in the UK ~1500 SGA children each year remain small, with no clear endocrine cause with rare genetic syndromes accounting for only a minority of cases. In order to define growth factor activation in these children we have initiated an assessment of cell growth and signalling in response to GH and IGF1 in fibroblast cell lines....
