From page 115...
... Bone marrow -- The soft, living tissue that fills most bone cavities and contains hematopoietic stem cells, from which all red and white blood cells evolve. The bone marrow also contains mesenchymal stem cells from which a number of cell types arise, including chondrocytes, which produce cartilage, and fibro blasts, which produce connective tissue.

... cells -- Cells found in a specific part of the embryo or fetus called the gonadal ridge that normally develop into mature gametes. The germ cells differentiate into the gametes (oocytes or sperm)

... Feeder cell layer -- Cells that are used in culture to maintain pluripotent stem cells. Feeder cells usually consist of mouse embryonic fibroblasts.

From page 118...
... -- A growth factor necessary for maintaining mouse embryonic stem cells in a proliferative, undifferentiated state. Mesenchymal stem cells -- Stem cells found in bone marrow and elsewhere from which a number of cell types can arise, including chondrocytes, which produce cartilage, and fibroblasts, which produce connective tissue.

From page 119...
... -- A procedure applied to IVF embryos to determine which ones carry deleterious mutations predisposing to hereditary diseases. Primary germ layers -- The three initial embryonic germ layers -- endoderm, meso derm, and ectoderm -- from which all other somatic tissue types develop.

... Produced experimentally in animals by inject ing pluripotent stem cells to determine the stem cells' abilities to differentiate into various types of tissues. Tissue culture -- Growth of tissue in vitro on an artificial medium for experimental research.
