Abstract__ Background Pluripotent embryonal carcinomas are good potential models to study in vitro the mechanisms that control differentiation during embryogenesis. The NT2 D1 cell line is a well known system of ectodermal differentiation. Retinoic acid RA induces a dorsal pattern of differentiation essentially neurons and bone morphogenetic protein BMP or hexamethylenebisacetamide HMBA induces a more ventral epidermal pattern of differentiation. However whether these human cells could give rise to mesoderm derivatives as their counterpart in mouse remained elusive. We analyzed the morphological characteristics and transcriptional activation of genes pertinent in cardiac muscle and endothelium differentiation during the growth of NT2 D1 cells in an inductive angiomyogenic medium with or without Bone Morphogenetic Protein 2 BMP2 . Results Our experiments showed
