Pluripotent embryonic stem cells (line BLC6), when cultivated in vitro as embryoid bodies and injected subcutaneously into syngeneic mice, form teratocarcinomas consisting of embryonal carcinoma cells and differentiated tissues of all three primary germ layers. In order to study the possible effects of the mammary-derived growth inhibitor (MDGI) on the differentiation pattern of the tumors developing in the mice, BLC6 cell-derived embryoid bodies were treated in vitro for 4 days with either MDGI or a synthetic peptide composed of the C-terminal 11 amino acids of MDGI. In those tumors, significantly more differentiated neural tissue and lesser proportions of undifferentiated embryonic carcinoma cells (ECC) were found in the MDGI- and peptide-treated groups, compared with controls. The results are discussed with respect to a possible differentiation-promoting capacity of MDGI.

D008648	Mesoderm	The middle germ layer of an embryo derived from three paired mesenchymal aggregates along the neural tube.

D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
D001755	Blastocyst	A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.

D002471	Cell Transformation, Neoplastic	Cell changes manifested by escape from control mechanisms, increased growth potential, alterations in the cell surface, karyotypic abnormalities, morphological and biochemical deviations from the norm, and other attributes conferring the ability to invade, metastasize, and kill.

D000074026	Fatty Acid Binding Protein 3	A small cytosolic fatty-acid binding protein that forms a lipid-binding beta-barrel structure and is expressed by CARDIOMYOCYTES and at lower levels in brain tissue. It is released into plasma immediately following cardiac injury and may therefore serve as a useful biomarker for the early detection of MYOCARDIAL INFARCTION.
