GH has diverse direct effects including the induction of lipolysis in adipocytes and mineralisation in bone. Interestingly, pluripotent mesenchymal stem cells can be isolated and cultured from adult bone marrow and induced to differentiate in vitro to both adipocytes and osteoblasts. GHR activation can be coupled to JAK2/STAT5 and the ERK (MAPK) pathway. We have therefore studied the evolution of GHR-associated cell signalling in adult rat BMSC’s during differentia...
